JFIF is a minimal or "low end" representation. -We recommend the use of TIFF/JPEG (TIFF revision 6.0 as modified by TIFF -Technical Note #2) for "high end" applications that need to record a lot of -additional data about an image. TIFF/JPEG is fairly new and not yet widely -supported, unfortunately. +Furthermore, the ISO committee pretends to be "responsible for the popular +JPEG" in their public reports which is not true because they don't respond to +actual requirements for the maintenance of the original JPEG specification. -The upcoming JPEG Part 3 standard defines a file format called SPIFF. -SPIFF is interoperable with JFIF, in the sense that most JFIF decoders should -be able to read the most common variant of SPIFF. SPIFF has some technical -advantages over JFIF, but its major claim to fame is simply that it is an -official standard rather than an informal one. At this point it is unclear -whether SPIFF will supersede JFIF or whether JFIF will remain the de-facto -standard.

Defining the symbol DONT_USE_EXTERN_C in the +configuration prevents this. (DP 202_jpeglib.h_c++.dpatch) + + +Version 6b 27-Mar-1998 +----------------------- + +jpegtran has new features for lossless image transformations (rotation +and flipping) as well as "lossless" reduction to grayscale. + +jpegtran now copies comments by default; it has a -copy switch to enable +copying all APPn blocks as well, or to suppress comments. (Formerly it +always suppressed comments and APPn blocks.) jpegtran now also preserves +JFIF version and resolution information. + +New decompressor library feature: COM and APPn markers found in the input +file can be saved in memory for later use by the application. (Before, +you had to code this up yourself with a custom marker processor.) + +There is an unused field "void * client_data" now in compress and decompress +parameter structs; this may be useful in some applications. + +JFIF version number information is now saved by the decoder and accepted by +the encoder. jpegtran uses this to copy the source file's version number, +to ensure "jpegtran -copy all" won't create bogus files that contain JFXX +extensions but claim to be version 1.01. Applications that generate their +own JFXX extension markers also (finally) have a supported way to cause the +encoder to emit JFIF version number 1.02. + +djpeg's trace mode reports JFIF 1.02 thumbnail images as such, rather +than as unknown APP0 markers. + +In -verbose mode, djpeg and rdjpgcom will try to print the contents of +APP12 markers as text. Some digital cameras store useful text information +in APP12 markers. + +Handling of truncated data streams is more robust: blocks beyond the one in +which the error occurs will be output as uniform gray, or left unchanged +if decoding a progressive JPEG. The appearance no longer depends on the +Huffman tables being used. + +Huffman tables are checked for validity much more carefully than before. + +To avoid the Unisys LZW patent, djpeg's GIF output capability has been +changed to produce "uncompressed GIFs", and cjpeg's GIF input capability +has been removed altogether. We're not happy about it either, but there +seems to be no good alternative. + +The configure script now supports building libjpeg as a shared library +on many flavors of Unix (all the ones that GNU libtool knows how to +build shared libraries for). Use "./configure --enable-shared" to +try this out. + +New jconfig file and makefiles for Microsoft Visual C++ and Developer Studio. +Also, a jconfig file and a build script for Metrowerks CodeWarrior +on Apple Macintosh. makefile.dj has been updated for DJGPP v2, and there +are miscellaneous other minor improvements in the makefiles. + +jmemmac.c now knows how to create temporary files following Mac System 7 +conventions. + +djpeg's -map switch is now able to read raw-format PPM files reliably. + +cjpeg -progressive -restart no longer generates any unnecessary DRI markers. + +Multiple calls to jpeg_simple_progression for a single JPEG object +no longer leak memory. + + +Version 6a 7-Feb-96 +-------------------- + +Library initialization sequence modified to detect version mismatches +and struct field packing mismatches between library and calling application. +This change requires applications to be recompiled, but does not require +any application source code change. + +All routine declarations changed to the style "GLOBAL(type) name ...", +that is, GLOBAL, LOCAL, METHODDEF, EXTERN are now macros taking the +routine's return type as an argument. This makes it possible to add +Microsoft-style linkage keywords to all the routines by changing just +these macros. Note that any application code that was using these macros +will have to be changed. + +DCT coefficient quantization tables are now stored in normal array order +rather than zigzag order. Application code that calls jpeg_add_quant_table, +or otherwise manipulates quantization tables directly, will need to be +changed. If you need to make such code work with either older or newer +versions of the library, a test like "#if JPEG_LIB_VERSION >= 61" is +recommended. + +djpeg's trace capability now dumps DQT tables in natural order, not zigzag +order. This allows the trace output to be made into a "-qtables" file +more easily. + +New system-dependent memory manager module for use on Apple Macintosh. + +Fix bug in cjpeg's -smooth option: last one or two scanlines would be +duplicates of the prior line unless the image height mod 16 was 1 or 2. + +Repair minor problems in VMS, BCC, MC6 makefiles. + +New configure script based on latest GNU Autoconf. + +Correct the list of include files needed by MetroWerks C for ccommand(). + +Numerous small documentation updates. + + +Version 6 2-Aug-95 +------------------- + +Progressive JPEG support: library can read and write full progressive JPEG +files. A "buffered image" mode supports incremental decoding for on-the-fly +display of progressive images. Simply recompiling an existing IJG-v5-based +decoder with v6 should allow it to read progressive files, though of course +without any special progressive display. + +New "jpegtran" application performs lossless transcoding between different +JPEG formats; primarily, it can be used to convert baseline to progressive +JPEG and vice versa. In support of jpegtran, the library now allows lossless +reading and writing of JPEG files as DCT coefficient arrays. This ability +may be of use in other applications. + +Notes for programmers: +* We changed jpeg_start_decompress() to be able to suspend; this makes all +decoding modes available to suspending-input applications. However, +existing applications that use suspending input will need to be changed +to check the return value from jpeg_start_decompress(). You don't need to +do anything if you don't use a suspending data source. +* We changed the interface to the virtual array routines: access_virt_array +routines now take a count of the number of rows to access this time. The +last parameter to request_virt_array routines is now interpreted as the +maximum number of rows that may be accessed at once, but not necessarily +the height of every access. + + +Version 5b 15-Mar-95 +--------------------- + +Correct bugs with grayscale images having v_samp_factor > 1. + +jpeg_write_raw_data() now supports output suspension. + +Correct bugs in "configure" script for case of compiling in +a directory other than the one containing the source files. + +Repair bug in jquant1.c: sometimes didn't use as many colors as it could. + +Borland C makefile and jconfig file work under either MS-DOS or OS/2. + +Miscellaneous improvements to documentation. + + +Version 5a 7-Dec-94 +-------------------- + +Changed color conversion roundoff behavior so that grayscale values are +represented exactly. (This causes test image files to change.) + +Make ordered dither use 16x16 instead of 4x4 pattern for a small quality +improvement. + +New configure script based on latest GNU Autoconf. +Fix configure script to handle CFLAGS correctly. +Rename *.auto files to *.cfg, so that configure script still works if +file names have been truncated for DOS. + +Fix bug in rdbmp.c: didn't allow for extra data between header and image. + +Modify rdppm.c/wrppm.c to handle 2-byte raw PPM/PGM formats for 12-bit data. + +Fix several bugs in rdrle.c. + +NEED_SHORT_EXTERNAL_NAMES option was broken. + +Revise jerror.h/jerror.c for more flexibility in message table. + +Repair oversight in jmemname.c NO_MKTEMP case: file could be there +but unreadable. + + +Version 5 24-Sep-94 +-------------------- + +Version 5 represents a nearly complete redesign and rewrite of the IJG +software. Major user-visible changes include: + * Automatic configuration simplifies installation for most Unix systems. + * A range of speed vs. image quality tradeoffs are supported. + This includes resizing of an image during decompression: scaling down + by a factor of 1/2, 1/4, or 1/8 is handled very efficiently. + * New programs rdjpgcom and wrjpgcom allow insertion and extraction + of text comments in a JPEG file. + +The application programmer's interface to the library has changed completely. +Notable improvements include: + * We have eliminated the use of callback routines for handling the + uncompressed image data. The application now sees the library as a + set of routines that it calls to read or write image data on a + scanline-by-scanline basis. + * The application image data is represented in a conventional interleaved- + pixel format, rather than as a separate array for each color channel. + This can save a copying step in many programs. + * The handling of compressed data has been cleaned up: the application can + supply routines to source or sink the compressed data.

It will thus be much the - * fastest option for images larger than main memory. - * - * The other routines require a set of destination virtual arrays, so they - * need twice as much memory as jpegtran normally does. The destination - * arrays are always written in normal scan order (top to bottom) because - * the virtual array manager expects this. The source arrays will be scanned - * in the corresponding order, which means multiple passes through the source - * arrays for most of the transforms. That could result in much thrashing - * if the image is larger than main memory. - * - * If cropping or trimming is involved, the destination arrays may be smaller - * than the source arrays. Note it is not possible to do horizontal flip - * in-place when a nonzero Y crop offset is specified, since we'd have to move - * data from one block row to another but the virtual array manager doesn't - * guarantee we can touch more than one row at a time.

Both the source and destination virtual arrays are allocated from the - * source JPEG object, and therefore should be manipulated by calling the - * source's memory manager. - * 2. The destination's component count should be used. It may be smaller - * than the source's when forcing to grayscale. - * 3. Likewise the destination's sampling factors should be used. When - * forcing to grayscale the destination's sampling factors will be all 1, - * and we may as well take that as the effective iMCU size. - * 4. When "trim" is in effect, the destination's dimensions will be the - * trimmed values but the source's will be untrimmed. - * 5. When "crop" is in effect, the destination's dimensions will be the - * cropped values but the source's will be uncropped. Each transform - * routine is responsible for picking up source data starting at the - * correct X and Y offset for the crop region. (The X and Y offsets - * passed to the transform routines are measured in iMCU blocks of the - * destination.) - * 6.

The right and bottom - * image edges are padded out to the next iMCU boundary with junk data; but - * no padding is possible at the top and left edges. If we were to flip - * the whole image including the pad data, then pad garbage would become - * visible at the top and/or left, and real pixels would disappear into the - * pad margins --- perhaps permanently, since encoders & decoders may not - * bother to preserve DCT blocks that appear to be completely outside the - * nominal image area. So, we have to exclude any partial iMCUs from the - * basic transformation. - * - * Transpose is the only transformation that can handle partial iMCUs at the - * right and bottom edges completely cleanly. flip_h can flip partial iMCUs - * at the bottom, but leaves any partial iMCUs at the right edge untouched. - * Similarly flip_v leaves any partial iMCUs at the bottom edge untouched. - * The other transforms are defined as combinations of these basic transforms - * and process edge blocks in a way that preserves the equivalence. - * - * The "trim" option causes untransformable partial iMCUs to be dropped; - * this is not strictly lossless, but it usually gives the best-looking - * result for odd-size images. Note that when this option is active, - * the expected mathematical equivalences between the transforms may not hold. - * (For example, -rot 270 -trim trims only the bottom edge, but -rot 90 -trim - * followed by -rot 180 -trim trims both edges.) - * - * We also offer a lossless-crop option, which discards data outside a given - * image region but losslessly preserves what is inside. Like the rotate and - * flip transforms, lossless crop is restricted by the JPEG format: the upper - * left corner of the selected region must fall on an iMCU boundary. If this - * does not hold for the given crop parameters, we silently move the upper left - * corner up and/or left to make it so, simultaneously increasing the region - * dimensions to keep the lower right crop corner unchanged. (Thus, the - * output image covers at least the requested region, but may cover more.) - * - * If both crop and a rotate/flip transform are requested, the crop is applied - * last --- that is, the crop region is specified in terms of the destination - * image. - * - * We also offer a "force to grayscale" option, which simply discards the - * chrominance channels of a YCbCr image.

It also adds fused + * multiply-accumulate instructions that work on the NEON registers. + * + * NOTE: Similarly, "VFPv4" might either reference VFPv4-D16 or VFPv4-D32 + * depending on context. + * + * The following information was determined by scanning the binutils-2.22 + * sources: + * + * Basic VFP instruction subsets: + * + * #define FPU_VFP_EXT_V1xD 0x08000000 // Base VFP instruction set. + * #define FPU_VFP_EXT_V1 0x04000000 // Double-precision insns. + * #define FPU_VFP_EXT_V2 0x02000000 // ARM10E VFPr1. + * #define FPU_VFP_EXT_V3xD 0x01000000 // VFPv3 single-precision. + * #define FPU_VFP_EXT_V3 0x00800000 // VFPv3 double-precision. + * #define FPU_NEON_EXT_V1 0x00400000 // Neon (SIMD) insns. + * #define FPU_VFP_EXT_D32 0x00200000 // Registers D16-D31. + * #define FPU_VFP_EXT_FP16 0x00100000 // Half-precision extensions. + * #define FPU_NEON_EXT_FMA 0x00080000 // Neon fused multiply-add + * #define FPU_VFP_EXT_FMA 0x00040000 // VFP fused multiply-add + * + * FPU types (excluding NEON) + * + * FPU_VFP_V1xD (EXT_V1xD) + * | + * +--------------------------+ + * | | + * FPU_VFP_V1 (+EXT_V1) FPU_VFP_V3xD (+EXT_V2+EXT_V3xD) + * | | + * | | + * FPU_VFP_V2 (+EXT_V2) FPU_VFP_V4_SP_D16 (+EXT_FP16+EXT_FMA) + * | + * FPU_VFP_V3D16 (+EXT_Vx3D+EXT_V3) + * | + * +--------------------------+ + * | | + * FPU_VFP_V3 (+EXT_D32) FPU_VFP_V4D16 (+EXT_FP16+EXT_FMA) + * | | + * | FPU_VFP_V4 (+EXT_D32) + * | + * FPU_VFP_HARD (+EXT_FMA+NEON_EXT_FMA) + * + * VFP architectures: + * + * ARCH_VFP_V1xD (EXT_V1xD) + * | + * +------------------+ + * | | + * | ARCH_VFP_V3xD (+EXT_V2+EXT_V3xD) + * | | + * | ARCH_VFP_V3xD_FP16 (+EXT_FP16) + * | | + * | ARCH_VFP_V4_SP_D16 (+EXT_FMA) + * | + * ARCH_VFP_V1 (+EXT_V1) + * | + * ARCH_VFP_V2 (+EXT_V2) + * | + * ARCH_VFP_V3D16 (+EXT_V3xD+EXT_V3) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V3D16_FP16 (+EXT_FP16) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V4_D16 (+EXT_FP16+EXT_FMA) + * | | + * | ARCH_VFP_V4 (+EXT_D32) + * | | + * | ARCH_NEON_VFP_V4 (+EXT_NEON+EXT_NEON_FMA) + * | + * ARCH_VFP_V3 (+EXT_D32) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V3_FP16 (+EXT_FP16) + * | + * ARCH_VFP_V3_PLUS_NEON_V1 (+EXT_NEON) + * | + * ARCH_NEON_FP16 (+EXT_FP16) + * + * -fpu= values and their correspondance with FPU architectures above: + * + * {"vfp", FPU_ARCH_VFP_V2}, + * {"vfp9", FPU_ARCH_VFP_V2}, + * {"vfp3", FPU_ARCH_VFP_V3}, // For backwards compatbility. + * {"vfp10", FPU_ARCH_VFP_V2}, + * {"vfp10-r0", FPU_ARCH_VFP_V1}, + * {"vfpxd", FPU_ARCH_VFP_V1xD}, + * {"vfpv2", FPU_ARCH_VFP_V2}, + * {"vfpv3", FPU_ARCH_VFP_V3}, + * {"vfpv3-fp16", FPU_ARCH_VFP_V3_FP16}, + * {"vfpv3-d16", FPU_ARCH_VFP_V3D16}, + * {"vfpv3-d16-fp16", FPU_ARCH_VFP_V3D16_FP16}, + * {"vfpv3xd", FPU_ARCH_VFP_V3xD}, + * {"vfpv3xd-fp16", FPU_ARCH_VFP_V3xD_FP16}, + * {"neon", FPU_ARCH_VFP_V3_PLUS_NEON_V1}, + * {"neon-fp16", FPU_ARCH_NEON_FP16}, + * {"vfpv4", FPU_ARCH_VFP_V4}, + * {"vfpv4-d16", FPU_ARCH_VFP_V4D16}, + * {"fpv4-sp-d16", FPU_ARCH_VFP_V4_SP_D16}, + * {"neon-vfpv4", FPU_ARCH_NEON_VFP_V4}, + * + * + * Simplified diagram that only includes FPUs supported by Android: + * Only ARCH_VFP_V3D16 is actually mandated by the armeabi-v7a ABI, + * all others are optional and must be probed at runtime. + * + * ARCH_VFP_V3D16 (EXT_V1xD+EXT_V1+EXT_V2+EXT_V3xD+EXT_V3) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V3D16_FP16 (+EXT_FP16) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V4_D16 (+EXT_FP16+EXT_FMA) + * | | + * | ARCH_VFP_V4 (+EXT_D32) + * | | + * | ARCH_NEON_VFP_V4 (+EXT_NEON+EXT_NEON_FMA) + * | + * ARCH_VFP_V3 (+EXT_D32) + * | + * +-------------------+ + * | | + * | ARCH_VFP_V3_FP16 (+EXT_FP16) + * | + * ARCH_VFP_V3_PLUS_NEON_V1 (+EXT_NEON) + * | + * ARCH_NEON_FP16 (+EXT_FP16) + * + */ diff --git a/3rdparty/libwebp/cpu-features/cpu-features.h b/3rdparty/libwebp/cpu-features/cpu-features.h new file mode 100644 index 000000000..f8553e88d --- /dev/null +++ b/3rdparty/libwebp/cpu-features/cpu-features.h @@ -0,0 +1,195 @@ +/* + * Copyright (C) 2010 The Android Open Source Project + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * * Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in + * the documentation and/or other materials provided with the + * distribution. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS + * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT + * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS + * FOR A PARTICULAR PURPOSE ARE DISCLAIMED.

The good news is that C++ if fully compatible with C so no compatibility issues can arise from making the change. Therefore, OpenCV with its 2.0 version introduced a new C++ interface that by taking advantage of these offers a new way of doing things. A way, in which you do not need to fiddle with memory management; making your code concise (less to write, to achieve more). The only main downside of the C++ interface is that many embedded development systems at the moment support only C.

While doing this is still a possibility, most of the OpenCV functions will allocate its output data manually.

In other words we use at all times only as much memory as we need to perform the task. -*Mat* is basically a class having two data parts: the matrix header (containing information such as the size of the matrix, the method used for storing, at which address is the matrix stored and so on) and a pointer to the matrix containing the pixel values (may take any dimensionality depending on the method chosen for storing) . The matrix header size is constant. However, the size of the matrix itself may vary from image to image and usually is larger by order of magnitudes. Therefore, when you're passing on images in your program and at some point you need to create a copy of the image the big price you will need to build is for the matrix itself rather than its header. OpenCV is an image processing library. It contains a large collection of image processing functions. To solve a computational challenge most of the time you will end up using multiple functions of the library. Due to this passing on images to functions is a common practice. We should not forget that we are talking about image processing algorithms, which tend to be quite computational heavy. The last thing we want to do is to further decrease the speed of your program by making unnecessary copies of potentially *large* images. +*Mat* is basically a class with two data parts: the matrix header (containing information such as the size of the matrix, the method used for storing, at which address is the matrix stored, and so on) and a pointer to the matrix containing the pixel values (taking any dimensionality depending on the method chosen for storing) .

However, if the performance numbers of an OpenCV implementation for the CPU do not satisfy you and you happen to have an NVidia CUDA GPU device in your system all is not lost. You may try to port or write your algorithm for the video card. This tutorial will give a good grasp on how to approach coding by using the GPU module of OpenCV. As a prerequisite you should already know how to handle the core, highgui and imgproc modules.

The full source code is quite long (due to the controlling of the application via the command line arguments and performance measurement). Therefore, to avoid cluttering up these sections with those you'll find here only the functions itself.

One for the CPU and two for the GPU. The reason I made two for the GPU is too illustrate that often simple porting your CPU to GPU will actually make it slower. If you want some performance gain you will need to remember a few rules, whose I'm going to detail later on. The development of the GPU module was made so that it resembles as much as possible its CPU counterpart. This is to make porting easy. The first thing you need to do before writing any code is to link the GPU module to your project, and include the header file for the module. All the functions and data structures of the GPU are in a *gpu* sub namespace of the *cv* namespace. You may add this to the default one via the *use namespace* keyword, or mark it everywhere explicitly via the cv:: to avoid confusion. I'll do the later. .. code-block:: cpp #include // GPU structures and methods GPU stands for **g**\ raphics **p**\ rocessing **u**\ nit. It was originally build to render graphical scenes. These scenes somehow build on a lot of data. Nevertheless, these aren't all dependent one from another in a sequential way and as it is possible a parallel processing of them. Due to this a GPU will contain multiple smaller processing units. These aren't the state of the art processors and on a one on one test with a CPU it will fall behind. However, its strength lies in its numbers. In the last years there has been an increasing trend to harvest these massive parallel powers of the GPU in non-graphical scene rendering too. This gave birth to the general-purpose computation on graphics processing units (GPGPU). The GPU has its own memory. When you read data from the hard drive with OpenCV into a *Mat* object that takes place in your systems memory. The CPU works somehow directly on this (via its cache), however the GPU cannot. He has too transferred the information he will use for calculations from the system memory to its own. This is done via an upload process and takes time. In the end the result will have to be downloaded back to your system memory for your CPU to see it and use it. Porting small functions to GPU is not recommended as the upload/download time will be larger than the amount you gain by a parallel execution. *Mat* objects are stored **only** in the system memory (or the CPU cache). For getting an OpenCV matrix to the GPU you'll need to use its GPU counterpart :gpudatastructure:`GpuMat `. It works similar to the *Mat* with a 2D only limitation and no reference returning for its functions (cannot mix GPU references with CPU ones). To upload a *Mat* object to the *GPU* you need to call the *upload* function after creating an instance of the class. To download you may use simple assignment to a *Mat* object or use the *download* function. .. code-block:: cpp Mat I1; // Main memory item - read image into with imread for example gpu::GpuMat gI; // GPU matrix - for now empty gI1.upload(I1); // Upload a data from the system memory to the GPU memory I1 = gI1; // Download, gI1.download(I1) will work too Once you have your data up in the GPU memory you may call GPU enabled functions of OpenCV. Most of the functions keep the same name just as on the CPU, with the difference that they only accept *GpuMat* inputs. A full list of these you will find in the documentation: `online here `_ or the OpenCV reference manual that comes with the source code. Another thing to keep in mind is that not for all channel numbers you can make efficient algorithms on the GPU. Generally, I found that the input images for the GPU images need to be either one or four channel ones and one of the char or float type for the item sizes. No double support on the GPU, sorry. Passing other types of objects for some functions will result in an exception thrown, and an error message on the error output. The documentation details in most of the places the types accepted for the inputs. If you have three channel images as an input you can do two things: either adds a new channel (and use char elements) or split up the image and call the function for each image. The first one isn't really recommended as you waste memory. For some functions, where the position of the elements (neighbor items) doesn't matter quick solution is to just reshape it into a single channel image. This is the case for the PSNR implementation where for the *absdiff* method the value of the neighbors is not important. However, for the *GaussianBlur* this isn't an option and such need to use the split method for the SSIM. With this knowledge you can already make a GPU viable code (like mine GPU one) and run it. You'll be surprised to see that it might turn out slower than your CPU implementation. Optimization ============ The reason for this is that you're throwing out on the window the price for memory allocation and data transfer. And on the GPU this is damn high. Another possibility for optimization is to introduce asynchronous OpenCV GPU calls too with the help of the :gpudatastructure:`gpu::Stream `. 1. Memory allocation on the GPU is considerable. Therefore, if it’s possible allocate new memory as few times as possible. If you create a function what you intend to call multiple times it is a good idea to allocate any local parameters for the function only once, during the first call. To do this you create a data structure containing all the local variables you will use. For instance in case of the PSNR these are: .. code-block:: cpp struct BufferPSNR // Optimized GPU versions { // Data allocations are very expensive on GPU. Use a buffer to solve: allocate once reuse later. gpu::GpuMat gI1, gI2, gs, t1,t2; gpu::GpuMat buf; }; Then create an instance of this in the main program: .. code-block:: cpp BufferPSNR bufferPSNR; And finally pass this to the function each time you call it: .. code-block:: cpp double getPSNR_GPU_optimized(const Mat& I1, const Mat& I2, BufferPSNR& b) Now you access these local parameters as: *b.gI1*, *b.buf* and so on. The GpuMat will only reallocate itself on a new call if the new matrix size is different from the previous one. #. Avoid unnecessary function data transfers. Any small data transfer will be significant one once you go to the GPU. Therefore, if possible make all calculations in-place (in other words do not create new memory objects - for reasons explained at the previous point). For example, although expressing arithmetical operations may be easier to express in one line formulas, it will be slower. In case of the SSIM at one point I need to calculate: .. code-block:: cpp b.t1 = 2 * b.mu1_mu2 + C1; Although the upper call will succeed observe that there is a hidden data transfer present. Before it makes the addition it needs to store somewhere the multiplication. Therefore, it will create a local matrix in the background, add to that the *C1* value and finally assign that to *t1*. To avoid this we use the gpu functions, instead of the arithmetic operators: .. code-block:: cpp gpu::multiply(b.mu1_mu2, 2, b.t1); //b.t1 = 2 * b.mu1_mu2 + C1; gpu::add(b.t1, C1, b.t1); #. Use asynchronous calls (the :gpudatastructure:`gpu::Stream `). By default whenever you call a gpu function it will wait for the call to finish and return with the result afterwards. However, it is possible to make asynchronous calls, meaning it will call for the operation execution, make the costly data allocations for the algorithm and return back right away. Now you can call another function if you wish to do so. For the MSSIM this is a small optimization point. In our default implementation we split up the image into channels and call then for each channel the gpu functions. A small degree of parallelization is possible with the stream. By using a stream we can make the data allocation, upload operations while the GPU is already executing a given method. For example we need to upload two images. We queue these one after another and call already the function that processes it. The functions will wait for the upload to finish, however while that happens makes the output buffer allocations for the function to be executed next. .. code-block:: cpp gpu::Stream stream; stream.enqueueConvert(b.gI1, b.t1, CV_32F); // Upload gpu::split(b.t1, b.vI1, stream); // Methods (pass the stream as final parameter). gpu::multiply(b.vI1[i], b.vI1[i], b.I1_2, stream); // I1^2 Result and conclusion ===================== On an Intel P8700 laptop CPU paired with a low end NVidia GT220M here are the performance numbers: .. code-block:: cpp Time of PSNR CPU (averaged for 10 runs): 41.4122 milliseconds.

    \ No newline at end of file +.. _gpuBasicsSimilarity: Similarity check (PNSR and SSIM) on the GPU ******************************************* Goal ==== In the :ref:`videoInputPSNRMSSIM` tutorial I already presented the PSNR and SSIM methods for checking the similarity between the two images. And as you could see there performing these takes quite some time, especially in the case of the SSIM. However, if the performance numbers of an OpenCV implementation for the CPU do not satisfy you and you happen to have an NVidia CUDA GPU device in your system all is not lost. You may try to port or write your algorithm for the video card. This tutorial will give a good grasp on how to approach coding by using the GPU module of OpenCV. As a prerequisite you should already know how to handle the core, highgui and imgproc modules. So, our goals are: .. container:: enumeratevisibleitemswithsquare + What's different compared to the CPU? + Create the GPU code for the PSNR and SSIM + Optimize the code for maximal performance The source code =============== You may also find the source code and these video file in the :file:`samples/cpp/tutorial_code/gpu/gpu-basics-similarity/gpu-basics-similarity` folder of the OpenCV source library or :download:`download it from here <../../../../samples/cpp/tutorial_code/gpu/gpu-basics-similarity/gpu-basics-similarity.cpp>`. The full source code is quite long (due to the controlling of the application via the command line arguments and performance measurement). Therefore, to avoid cluttering up these sections with those you'll find here only the functions itself. The PSNR returns a float number, that if the two inputs are similar between 30 and 50 (higher is better). .. literalinclude:: ../../../../samples/cpp/tutorial_code/gpu/gpu-basics-similarity/gpu-basics-similarity.cpp :language: cpp :linenos: :tab-width: 4 :lines: 165-210, 18-23, 210-235 The SSIM returns the MSSIM of the images. This is too a float number between zero and one (higher is better), however we have one for each channel. Therefore, we return a *Scalar* OpenCV data structure: .. literalinclude:: ../../../../samples/cpp/tutorial_code/gpu/gpu-basics-similarity/gpu-basics-similarity.cpp :language: cpp :linenos: :tab-width: 4 :lines: 235-355, 26-42, 357- How to do it? - The GPU ======================= Now as you can see we have three types of functions for each operation. One for the CPU and two for the GPU. The reason I made two for the GPU is too illustrate that often simple porting your CPU to GPU will actually make it slower. If you want some performance gain you will need to remember a few rules, whose I'm going to detail later on. The development of the GPU module was made so that it resembles as much as possible its CPU counterpart. This is to make porting easy. The first thing you need to do before writing any code is to link the GPU module to your project, and include the header file for the module. All the functions and data structures of the GPU are in a *gpu* sub namespace of the *cv* namespace. You may add this to the default one via the *use namespace* keyword, or mark it everywhere explicitly via the cv:: to avoid confusion. I'll do the later. .. code-block:: cpp #include // GPU structures and methods GPU stands for **g**\ raphics **p**\ rocessing **u**\ nit. It was originally build to render graphical scenes. These scenes somehow build on a lot of data. Nevertheless, these aren't all dependent one from another in a sequential way and as it is possible a parallel processing of them. Due to this a GPU will contain multiple smaller processing units. These aren't the state of the art processors and on a one on one test with a CPU it will fall behind. However, its strength lies in its numbers. In the last years there has been an increasing trend to harvest these massive parallel powers of the GPU in non-graphical scene rendering too. This gave birth to the general-purpose computation on graphics processing units (GPGPU). The GPU has its own memory. When you read data from the hard drive with OpenCV into a *Mat* object that takes place in your systems memory. The CPU works somehow directly on this (via its cache), however the GPU cannot. He has too transferred the information he will use for calculations from the system memory to its own. This is done via an upload process and takes time. In the end the result will have to be downloaded back to your system memory for your CPU to see it and use it. Porting small functions to GPU is not recommended as the upload/download time will be larger than the amount you gain by a parallel execution. Mat objects are stored only in the system memory (or the CPU cache). For getting an OpenCV matrix to the GPU you'll need to use its GPU counterpart :gpudatastructure:`GpuMat `. It works similar to the Mat with a 2D only limitation and no reference returning for its functions (cannot mix GPU references with CPU ones). To upload a Mat object to the GPU you need to call the upload function after creating an instance of the class. To download you may use simple assignment to a Mat object or use the download function. .. code-block:: cpp Mat I1; // Main memory item - read image into with imread for example gpu::GpuMat gI; // GPU matrix - for now empty gI1.upload(I1); // Upload a data from the system memory to the GPU memory I1 = gI1; // Download, gI1.download(I1) will work too Once you have your data up in the GPU memory you may call GPU enabled functions of OpenCV. Most of the functions keep the same name just as on the CPU, with the difference that they only accept *GpuMat* inputs. A full list of these you will find in the documentation: `online here `_ or the OpenCV reference manual that comes with the source code. Another thing to keep in mind is that not for all channel numbers you can make efficient algorithms on the GPU. Generally, I found that the input images for the GPU images need to be either one or four channel ones and one of the char or float type for the item sizes. No double support on the GPU, sorry. Passing other types of objects for some functions will result in an exception thrown, and an error message on the error output. The documentation details in most of the places the types accepted for the inputs. If you have three channel images as an input you can do two things: either adds a new channel (and use char elements) or split up the image and call the function for each image. The first one isn't really recommended as you waste memory. For some functions, where the position of the elements (neighbor items) doesn't matter quick solution is to just reshape it into a single channel image.

For example, a valid command line would look like: .. code-block:: bash video-write.exe video/Megamind.avi R Y The source code =============== You may also find the source code and these video file in the :file:`samples/cpp/tutorial_code/highgui/video-write/` folder of the OpenCV source library or :download:`download it from here <../../../../samples/cpp/tutorial_code/HighGUI/video-write/video-write.cpp>`. .. literalinclude:: ../../../../samples/cpp/tutorial_code/HighGUI/video-write/video-write.cpp :language: cpp :linenos: :tab-width: 4 :lines: 1-8, 21-22, 24-97 The structure of a video ======================== For start, you should have an idea of just how a video file looks. Every video file in itself is a container. The type of the container is expressed in the files extension (for example *avi*, *mov* or *mkv*). This contains multiple elements like: video feeds, audio feeds or other tracks (like for example subtitles). How these feeds are stored is determined by the codec used for each one of them. In case of the audio tracks commonly used codecs are *mp3* or *aac*. For the video files the list is somehow longer and includes names such as *XVID*, *DIVX*, *H264* or *LAGS* (*Lagarith Lossless Codec*). The full list of codecs you may use on a system depends on just what one you have installed. .. image:: images/videoFileStructure.png :alt: The Structure of the video :align: center As you can see things can get really complicated with videos. However, OpenCV is mainly a computer vision library, not a video stream, codec and write one. Therefore, the developers tried to keep this part as simple as possible. Due to this OpenCV for video containers supports only the *avi* extension, its first version. A direct limitation of this is that you cannot save a video file larger than 2 GB. Furthermore you can only create and expand a single video track inside the container. No audio or other track editing support here. Nevertheless, any video codec present on your system might work. If you encounter some of these limitations you will need to look into more specialized video writing libraries such as *FFMpeg* or codecs as *HuffYUV*, *CorePNG* and *LCL*. As an alternative, create the video track with OpenCV and expand it with sound tracks or convert it to other formats by using video manipulation programs such as *VirtualDub* or *AviSynth*. The *VideoWriter* class ======================= The content written here builds on the assumption you already read the :ref:`videoInputPSNRMSSIM` tutorial and you know how to read video files. To create a video file you just need to create an instance of the :huivideo:`VideoWriter ` class. You can specify its properties either via parameters in the constructor or later on via the :huivideo:`open ` function. Either way, the parameters are the same: 1. The name of the output that contains the container type in its extension. At the moment only *avi* is supported. We construct this from the input file, add to this the name of the channel to use, and finish it off with the container extension. .. code-block:: cpp const string source = argv[1]; // the source file name string::size_type pAt = source.find_last_of('.'); // Find extension point const string NAME = source.substr(0, pAt) + argv[2][0] + ".avi"; // Form the new name with container #. The codec to use for the video track. Now all the video codecs have a unique short name of maximum four characters. Hence, the *XVID*, *DIVX* or *H264* names. This is called a four character code. You may also ask this from an input video by using its *get* function. Because the *get* function is a general function it always returns double values. A double value is stored on 64 bits. Four characters are four bytes, meaning 32 bits. These four characters are coded in the lower 32 bits of the *double*. A simple way to throw away the upper 32 bits would be to just convert this value to *int*: .. code-block:: cpp VideoCapture inputVideo(source); // Open input int ex = static_cast(inputVideo.get(CV_CAP_PROP_FOURCC)); // Get Codec Type- Int form OpenCV internally works with this integer type and expect this as its second parameter. Now to convert from the integer form to string we may use two methods: a bitwise operator and a union method. The first one extracting from an int the characters looks like (an "and" operation, some shifting and adding a 0 at the end to close the string): .. code-block:: cpp char EXT[] = {ex & 0XFF , (ex & 0XFF00) >> 8,(ex & 0XFF0000) >> 16,(ex & 0XFF000000) >> 24, 0}; You can do the same thing with the *union* as: .. code-block:: cpp union { int v; char c[5];} uEx ; uEx.v = ex; // From Int to char via union uEx.c[4]='\0'; The advantage of this is that the conversion is done automatically after assigning, while for the bitwise operator you need to do the operations whenever you change the codec type. In case you know the codecs four character code beforehand, you can use the *CV_FOURCC* macro to build the integer: .. code-block::cpp CV_FOURCC('P','I','M,'1') // this is an MPEG1 codec from the characters to integer If you pass for this argument minus one than a window will pop up at runtime that contains all the codec installed on your system and ask you to select the one to use: .. image:: images/videoCompressSelect.png :alt: Select the codec type to use :align: center #. The frame per second for the output video. Again, here I keep the input videos frame per second by using the *get* function. #. The size of the frames for the output video. Here too I keep the input videos frame size per second by using the *get* function. #. The final argument is an optional one. By default is true and says that the output will be a colorful one (so for write you will send three channel images). To create a gray scale video pass a false parameter here. Here it is, how I use it in the sample: .. code-block:: cpp VideoWriter outputVideo; Size S = Size((int) inputVideo.get(CV_CAP_PROP_FRAME_WIDTH), //Acquire input size (int) inputVideo.get(CV_CAP_PROP_FRAME_HEIGHT)); outputVideo.open(NAME , ex, inputVideo.get(CV_CAP_PROP_FPS),S, true); Afterwards, you use the :huivideo:`isOpened() ` function to find out if the open operation succeeded or not. The video file automatically closes when the *VideoWriter* object is destroyed. After you open the object with success you can send the frames of the video in a sequential order by using the :huivideo:`write` function of the class. Alternatively, you can use its overloaded operator << : .. code-block:: cpp outputVideo.write(res); //or outputVideo << res; Extracting a color channel from an RGB image means to set to zero the RGB values of the other channels. You can either do this with image scanning operations or by using the split and merge operations. You first split the channels up into different images, set the other channels to zero images of the same size and type and finally merge them back: .. code-block:: cpp split(src, spl); // process - extract only the correct channel for( int i =0; i < 3; ++i) if (i != channel) spl[i] = Mat::zeros(S, spl[0].type()); merge(spl, res); Put all this together and you'll get the upper source code, whose runtime result will show something around the idea: .. image:: images/resultOutputWideoWrite.png :alt: A sample output :align: center You may observe a runtime instance of this on the `YouTube here `_. .. raw:: html

By the first steps we create blank activity and default view layout. The simplest +OpenCV-centric application must implement OpenCV initialization, create its own view to show +preview from camera and implements ``CvViewFrameListener2`` interface to get frames from camera and +process it. - protected Bitmap processFrame(VideoCapture capture) { - Mat mRgba = new Mat(); - capture.retrieve(mRgba, Highgui.CV_CAP_ANDROID_COLOR_FRAME_RGBA); - //process mRgba - Bitmap bmp = Bitmap.createBitmap(mRgba.cols(), mRgba.rows(), Bitmap.Config.ARGB_8888); - try { - Utils.matToBitmap(mRgba, bmp); - } catch(Exception e) { - Log.e("processFrame", "Utils.matToBitmap() throws an exception: " + e.getMessage()); - bmp.recycle(); - bmp = null; - } - return bmp; - } +First of all we create our application view using xml layout. Our layout consists of the only +one full screen component of class ``org.opencv.android.JavaCameraView``. This class is +implemented inside OpenCV library. It is inherited from ``CameraBridgeViewBase``, that extends +``SurfaceView`` and uses standard Android camera API. Alternatively you can use +``org.opencv.android.NativeCameraView`` class, that implements the same interface, but uses +``VideoCapture`` class as camera access back-end. ``opencv:show_fps="true"`` and +``opencv:camera_id="any"`` options enable FPS message and allow to use any camera on device. +Application tries to use back camera first. + +After creating layout we need to implement ``Activity`` class. OpenCV initialization process has +been already discussed above. In this sample we use asynchronous initialization. Implementation of +``CvCameraViewListener`` interface allows you to add processing steps after frame grabbing from +camera and before its rendering on screen. The most important function is ``onCameraFrame``. It is +callback function and it is called on retrieving frame from camera.

Luckily, OpenCV is an *open source project*. This means that in theory anyone has access to the full source code and may extend it. While making a robust and practical library (like OpenCV) is great, the success of a library also depends on how user friendly it is. To improve on this aspect, the OpenCV team has already been listening to user feedback from its :opencv_group:`Yahoo user group <>` and by making samples you can find in the source directories sample folder. The addition of the tutorials (in both online and PDF format) is an extension of these efforts. Goal ==== .. _reST: http://docutils.sourceforge.net/rst.html .. |reST| replace:: reStructuredText .. |Sphinx| replace:: Sphinx .. _Sphinx: http://sphinx.pocoo.org/ The tutorials are just as an important part of the library as the implementation of those crafty data structures and algorithms you can find in OpenCV. Therefore, the source codes for the tutorials are part of the library. And yes, I meant source codes. The reason for this formulation is that the tutorials are written by using the |Sphinx|_ documentation generation system. This is based on the popular python documentation system called |reST|_ (reST). ReStructuredText is a really neat language that by using a few simple conventions (indentation, directives) and emulating old school e-mail writing techniques (text only) tries to offer a simple way to create and edit documents. Sphinx extends this with some new features and creates the resulting document in both HTML (for web) and PDF (for offline usage) format. Usually, an OpenCV tutorial has the following parts: 1. A source code demonstration of an OpenCV feature: a. One or more CPP, Python, Java or other type of files depending for what OpenCV offers support and for what language you make the tutorial. #. Occasionaly, input resource files required for running your tutorials application. #. A table of content entry (so people may easily find the tutorial): a. Adding your stuff to the tutorials table of content (**reST** file). #. Add an image file near the TOC entry. #. The content of the tutorial itself: a. The **reST** text of the tutorial #. Images following the idea that "*A picture is worth a thousand words*". #. For more complex demonstrations you may create a video. As you can see you will need at least some basic knowledge of the *reST* system in order to complete the task at hand with success. However, don't worry *reST* (and *Sphinx*) was made with simplicity in mind. It is easy to grasp its basics. I found that the `OpenAlea documentations introduction on this subject `_ (or the `Thomas Cokelaer one `_ ) should enough for this. If for some directive or feature you need a more in-depth description look it up in the official |reST|_ help files or at the |Sphinx|_ documentation. In our world achieving some tasks is possible in multiple ways. However, some of the roads to take may have obvious or hidden advantages over others. Then again, in some other cases it may come down to just simple user preference. Here, I'll present how I decided to write the tutorials, based on my personal experience. If for some of them you know a better solution and you can back it up feel free to use that. I've nothing against it, as long as it gets the job done in an elegant fashion. Now the best would be if you could make the integration yourself. For this you need first to have the source code. I recommend following the guides for your operating system on acquiring OpenCV sources. For Linux users look :ref:`here ` and for :ref:`Windows here `. You must also install python and sphinx with its dependencies in order to be able to build the documentation. Once you have downloaded the repository to your hard drive you can take a look in the OpenCV directory to make sure you have both the samples and doc folder present. Anyone may download the trunk source files from :file:`git://code.opencv.org/opencv.git` . Nevertheless, not everyone has upload (commit/submit) rights. This is to protect the integrity of the library. If you plan doing more than one tutorial, and would like to have an account with commit user rights you should first register an account at http://code.opencv.org/ and then contact dr. Gary Bradski at -delete-bradski@-delete-willowgarage.com. Otherwise, you can just send the resulting files to us via the :opencv_group:`Yahoo user group <>` or to me at -delete-bernat@-delete-primeranks.net and I'll add it. If you have questions, suggestions or constructive critics I will gladly listen to them. If you send it to the OpenCV group please tag its subject with a **[Tutorial]** entry. Format the Source Code ====================== Before I start this let it be clear: the main goal is to have a working sample code. However, for your tutorial to be of a top notch quality you should follow a few guide lines I am going to present here. In case you have an application by using the older interface (with *IplImage*, *CVMat*, *cvLoadImage* and such) consider migrating it to the new C++ interface. The tutorials are intended to be an up to date help for our users. And as of OpenCV 2 the OpenCV emphasis on using the less error prone and clearer C++ interface. Therefore, if possible please convert your code to the C++ interface. For this it may help to read the :ref:`InteroperabilityWithOpenCV1` tutorial. However, once you have an OpenCV 2 working code, then you should make your source code snippet as easy to read as possible. Here're a couple of advices for this: .. container:: enumeratevisibleitemswithsquare + Add a standard output with the description of what your program does. Keep it short and yet, descriptive. This output is at the start of the program. In my example files this usually takes the form of a *help* function containing the output. This way both the source file viewer and application runner can see what all is about in your sample. Here's an instance of this: .. code-block:: cpp void help() { cout << "--------------------------------------------------------------------------" << endl << "This program shows how to write video files. You can extract the R or G or B color channel " << " of the input video. You can choose to use the source codec (Y) or select a custom one. (N)"<< endl << "Usage:" << endl << "./video-write inputvideoName [ R | G | B] [Y | N]" << endl << "--------------------------------------------------------------------------" << endl << endl; } // ... int main(int argc, char *argv[], char *window_name) { help(); // here comes the actual source code } Additionally, finalize the description with a short usage guide. This way the user will know how to call your programs, what leads us to the next point. + Prefer command line argument controlling instead of hard coded one. If your program has some variables that may be changed use command line arguments for this. The tutorials, can be a simple try-out ground for the user. If you offer command line controlling for the input image (for example), then you offer the possibility for the user to try it out with his/her own images, without the need to mess in the source code. In the upper example you can see that the input image, channel and codec selection may all be changed from the command line. Just compile the program and run it with your own input arguments. + Be as verbose as possible. There is no shame in filling the source code with comments. This way the more advanced user may figure out what's happening right from the sample code. This advice goes for the output console too. Specify to the user what's happening. Never leave the user hanging there and thinking on: "Is this program now crashing or just doing some computationally intensive task?." So, if you do a training task that may take some time, make sure you print out a message about this before starting and after finishing it. + Throw out unnecessary stuff from your source code. This is a warning to not take the previous point too seriously. Balance is the key. If it's something that can be done in a fewer lines or simpler than that's the way you should do it. Nevertheless, if for some reason you have such sections notify the user why you have chosen to do so. Keep the amount of information as low as possible, while still getting the job done in an elegant way. + Put your sample file into the :file:`opencv/samples/cpp/tutorial_code/sectionName` folder. If you write a tutorial for other languages than cpp, then change that part of the path. Before completing this you need to decide that to what section (module) does your tutorial goes. Think about on what module relies most heavily your code and that is the one to use. If the answer to this question is more than one modules then the *general* section is the one to use. For finding the *opencv* directory open up your file system and navigate where you downloaded our repository. + If the input resources are hard to acquire for the end user consider adding a few of them to the :file:`opencv/samples/cpp/tutorial_code/images`. Make sure that who reads your code can try it out! Add the TOC entry ================= For this you will need to know some |reST|_. There is no going around this. |reST|_ files have **rst** extensions. However, these are simple text files. Use any text editor you like. Finding a text editor that offers syntax highlighting for |reST|_ was quite a challenge at the time of writing this tutorial. In my experience, `Intype `_ is a solid option on Windows, although there is still place for improvement. Adding your source code to a table of content is important for multiple reasons. First and foremost this will allow for the user base to find your tutorial from our websites tutorial table of content. Secondly, if you omit this *Sphinx* will throw a warning that your tutorial file isn't part of any TOC tree entry. And there is nothing more than the developer team hates than an ever increasing warning/error list for their builds. *Sphinx* also uses this to build up the previous-back-up buttons on the website. Finally, omitting this step will lead to that your tutorial will **not** be added to the PDF version of the tutorials. Navigate to the :file:`opencv/doc/tutorials/section/table_of_content_section` folder (where the section is the module to which you're adding the tutorial). Open the *table_of_content_section* file. Now this may have two forms. If no prior tutorials are present in this section that there is a template message about this and has the following form: .. code-block:: rst .. _Table-Of-Content-Section: Section title ----------------------------------------------------------- Description about the section. .. include:: ../../definitions/noContent.rst .. raw:: latex \pagebreak The first line is a reference to the section title in the reST system. The section title will be a link and you may refer to it via the ``:ref:`` directive. The *include* directive imports the template text from the definitions directories *noContent.rst* file. *Sphinx* does not creates the PDF from scratch. It does this by first creating a latex file. Then creates the PDF from the latex file. With the *raw* directive you can directly add to this output commands. Its unique argument is for what kind of output to add the content of the directive. For the PDFs it may happen that multiple sections will overlap on a single page. To avoid this at the end of the TOC we add a *pagebreak* latex command, that hints to the LATEX system that the next line should be on a new page. If you have one of this, try to transform it to the following form: .. include:: ../../definitions/tocDefinitions.rst .. code-block:: rst .. _Table-Of-Content-Section: Section title ----------------------------------------------------------- .. include:: ../../definitions/tocDefinitions.rst + .. tabularcolumns:: m{100pt} m{300pt} .. cssclass:: toctableopencv =============== ====================================================== |MatBasicIma| **Title:** :ref:`matTheBasicImageContainer` *Compatibility:* > OpenCV 2.0 *Author:* |Author_BernatG| You will learn how to store images in the memory and how to print out their content to the console. =============== ===================================================== .. |MatBasicIma| image:: images/matTheBasicImageStructure.jpg :height: 90pt :width: 90pt .. raw:: latex \pagebreak .. toctree:: :hidden: ../mat - the basic image container/mat - the basic image container If this is already present just add a new section of the content between the include and the raw directives (excluding those lines). Here you'll see a new include directive. This should be present only once in a TOC tree and the reST file contains the definitions of all the authors contributing to the OpenCV tutorials. We are a multicultural community and some of our name may contain some funky characters. However, reST **only supports** ANSI characters. Luckily we can specify Unicode characters with the *unicode* directive. Doing this for all of your tutorials is a troublesome procedure. Therefore, the tocDefinitions file contains the definition of your author name. Add it here once and afterwards just use the replace construction. For example here's the definition for my name: .. code-block:: rst .. |Author_BernatG| unicode:: Bern U+00E1 t U+0020 G U+00E1 bor The ``|Author_BernatG|`` is the text definitions alias. I can use later this to add the definition, like I've done in the TOCs *Author* part. After the ``::`` and a space you start the definition. If you want to add an UNICODE character (non-ASCI) leave an empty space and specify it in the format U+(UNICODE code). To find the UNICODE code of a character I recommend using the `FileFormat `_ websites service. Spaces are trimmed from the definition, therefore we add a space by its UNICODE character (U+0020). Until the *raw* directive what you can see is a TOC tree entry. Here's how a TOC entry will look like: + .. tabularcolumns:: m{100pt} m{300pt} .. cssclass:: toctableopencv =============== ====================================================== |MatBasicIma| **Title:** :ref:`matTheBasicImageContainer` *Compatibility:* > OpenCV 2.0 *Author:* |Author_BernatG| You will learn how to store images in the memory and how to print out their content to the console. =============== ====================================================== .. |MatBasicIma| image:: images/matTheBasicImageStructure.jpg :height: 90pt :width: 90pt As you can see we have an image to the left and a description box to the right. To create two boxes we use a table with two columns and a single row. In the left column is the image and in the right one the description. However, the image directive is way too long to fit in a column. Therefore, we need to use the substitution definition system. We add this definition after the TOC tree. All images for the TOC tree are to be put in the images folder near its |reST|_ file. We use the point measurement system because we are also creating PDFs. PDFs are printable documents, where there is no such thing that pixels (px), just points (pt). And while generally space is no problem for web pages (we have monitors with **huge** resolutions) the size of the paper (A4 or letter) is constant and will be for a long time in the future. Therefore, size constrains come in play more like for the PDF, than the generated HTML code. Now your images should be as small as possible, while still offering the intended information for the user. Remember that the tutorial will become part of the OpenCV source code. If you add large images (that manifest in form of large image size) it will just increase the size of the repository pointlessly. If someone wants to download it later, its download time will be that much longer. Not to mention the larger PDF size for the tutorials and the longer load time for the web pages. In terms of pixels a TOC image should not be larger than 120 X 120 pixels. Resize your images if they are larger! .. note:: If you add a larger image and specify a smaller image size, *Sphinx* will not resize that. At build time will add the full size image and the resize will be done by your browser after the image is loaded. A 120 X 120 image is somewhere below 10KB. If you add a 110KB image, you have just pointlessly added a 100KB extra data to transfer over the internet for every user! Generally speaking you shouldn't need to specify your images size (excluding the TOC entries). If no such is found *Sphinx* will use the size of the image itself (so no resize occurs). Then again if for some reason you decide to specify a size that should be the **width** of the image rather than its height. The reason for this again goes back to the PDFs. On a PDF page the height is larger than the width. In the PDF the images will not be resized. If you specify a size that does not fit in the page, then what does not fits in **will be cut off**. When creating your images for your tutorial you should try to keep the image widths below 500 pixels, and calculate with around 400 point page width when specifying image widths. The image format depends on the content of the image. If you have some complex scene (many random like colors) then use *jpg*. Otherwise, prefer using *png*. They are even some tools out there that optimize the size of *PNG* images, such as `PNGGauntlet `_. Use them to make your images as small as possible in size. Now on the right side column of the table we add the information about the tutorial: .. container:: enumeratevisibleitemswithsquare + In the first line it is the title of the tutorial. However, there is no need to specify it explicitly. We use the reference system. We'll start up our tutorial with a reference specification, just like in case of this TOC entry with its `` .. _Table-Of-Content-Section:`` . If after this you have a title (pointed out by the following line of -), then Sphinx will replace the ``:ref:`Table-Of-Content-Section``` directive with the tile of the section in reference form (creates a link in web page). Here's how the definition looks in my case: .. code-block:: rst .. _matTheBasicImageContainer: Mat - The Basic Image Container ******************************* Note, that according to the |reST|_ rules the * should be as long as your title. + Compatibility. What version of OpenCV is required to run your sample code. + Author. Use the substitution markup of |reST|_. + A short sentence describing the essence of your tutorial. Now before each TOC entry you need to add the three lines of: .. code-block:: cpp + .. tabularcolumns:: m{100pt} m{300pt} .. cssclass:: toctableopencv The plus sign (+) is to enumerate tutorials by using bullet points. So for every TOC entry we have a corresponding bullet point represented by the +. Sphinx is highly indenting sensitive. Indentation is used to express from which point until to which point does a construction last. Un-indentation means end of that construction. So to keep all the bullet points to the same group the following TOC entries (until the next +) should be indented by two spaces. Here, I should also mention that **always** prefer using spaces instead of tabs. Working with only spaces makes possible that if we both use monotype fonts we will see the same thing. Tab size is text editor dependent and as should be avoided. *Sphinx* translates all tabs into 8 spaces before interpreting it. It turns out that the automatic formatting of both the HTML and PDF(LATEX) system messes up our tables. Therefore, we need to help them out a little. For the PDF generation we add the ``.. tabularcolumns:: m{100pt} m{300pt}`` directive. This means that the first column should be 100 points wide and middle aligned. For the HTML look we simply name the following table of a *toctableopencv* class type. Then, we can modify the look of the table by modifying the CSS of our web page. The CSS definitions go into the :file:`opencv/doc/_themes/blue/static/default.css_t` file. .. code-block:: css .toctableopencv { width: 100% ; table-layout: fixed; } .toctableopencv colgroup col:first-child { width: 100pt !important; max-width: 100pt !important; min-width: 100pt !important; } .toctableopencv colgroup col:nth-child(2) { width: 100% !important; } However, you should not need to modify this. Just add these three lines (plus keep the two space indentation) for all TOC entries you add. At the end of the TOC file you'll find: .. code-block:: rst .. raw:: latex \pagebreak .. toctree:: :hidden: ../mat - the basic image container/mat - the basic image container The page break entry comes for separating sections and should be only one in a TOC tree |reST|_ file. Finally, at the end of the TOC tree we need to add our tutorial to the *Sphinx* TOC tree system. *Sphinx* will generate from this the previous-next-up information for the HTML file and add items to the PDF according to the order here. By default this TOC tree directive generates a simple table of contents. However, we already created a fancy looking one so we no longer need this basic one. Therefore, we add the *hidden* option to do not show it. The path is of a relative type. We step back in the file system and then go into the :file:`mat - the basic image container` directory for the :file:`mat - the basic image container.rst` file. Putting out the *rst* extension for the file is optional. Write the tutorial ================== Create a folder with the name of your tutorial. Preferably, use small letters only. Then create a text file in this folder with *rst* extension and the same name. If you have images for the tutorial create an :file:`images` folder and add your images there. When creating your images follow the guidelines described in the previous part! Now here's our recommendation for the structure of the tutorial (although, remember that this is not carved in the stone; if you have a better idea, use it!): .. container:: enumeratevisibleitemswithsquare + Create the reference point and the title. .. code-block:: rst .. _matTheBasicImageContainer: Mat - The Basic Image Container ******************************* You start the tutorial by specifying a reference point by the ``.. _matTheBasicImageContainer:`` and then its title. The name of the reference point should be a unique one over the whole documentation. Therefore, do not use general names like *tutorial1*. Use the * character to underline the title for its full width. The subtitles of the tutorial should be underlined with = charachter. + Goals. You start your tutorial by specifying what you will present. You can also enumerate the sub jobs to be done. For this you can use a bullet point construction. There is a single configuration file for both the reference manual and the tutorial documentation. In the reference manuals at the argument enumeration we do not want any kind of bullet point style enumeration. Therefore, by default all the bullet points at this level are set to do not show the dot before the entries in the HTML. You can override this by putting the bullet point in a container. I've defined a square type bullet point view under the name *enumeratevisibleitemswithsquare*. The CSS style definition for this is again in the :file:`opencv\doc\_themes\blue\static\default.css_t` file. Here's a quick example of using it: .. code-block:: rst .. container:: enumeratevisibleitemswithsquare + Create the reference point and the title. + Second entry + Third entry Note that you need the keep the indentation of the container directive. Directive indentations are always three (3) spaces. Here you may even give usage tips for your sample code. + Source code. Present your samples code to the user. It's a good idea to offer a quick download link for the HTML page by using the *download* directive and pointing out where the user may find your source code in the file system by using the *file* directive: .. code-block:: rst Text :file:`samples/cpp/tutorial_code/highgui/video-write/` folder of the OpenCV source library or :download:`text to appear in the webpage <../../../../samples/cpp/tutorial_code/HighGUI/video-write/video-write.cpp>`. For the download link the path is a relative one, hence the multiple back stepping operations (..). Then you can add the source code either by using the *code block* directive or the *literal include* one. In case of the code block you will need to actually add all the source code text into your |reST|_ text and also apply the required indentation: .. code-block:: rst .. code-block:: cpp int i = 0; l = ++j; The only argument of the directive is the language used (here CPP). Then you add the source code into its content (meaning one empty line after the directive) by keeping the indentation of the directive (3 spaces). With the *literal include* directive you do not need to add the source code of the sample. You just specify the sample and *Sphinx* will load it for you, during build time. Here's an example usage: .. code-block:: rst .. literalinclude:: ../../../../samples/cpp/tutorial_code/HighGUI/video-write/video-write.cpp :language: cpp :linenos: :tab-width: 4 :lines: 1-8, 21-22, 24- After the directive you specify a relative path to the file from what to import. It has four options: the language to use, if you add the ``:linenos:`` the line numbers will be shown, you can specify the tab size with the ``:tab-width:`` and you do not need to load the whole file, you can show just the important lines. Use the *lines* option to do not show redundant information (such as the *help* function). Here basically you specify ranges, if the second range line number is missing than that means that until the end of the file. The ranges specified here do no need to be in an ascending order, you may even reorganize the structure of how you want to show your sample inside the tutorial. + The tutorial. Well here goes the explanation for why and what have you used. Try to be short, clear, concise and yet a thorough one. There's no magic formula. Look into a few already made tutorials and start out from there. Try to mix sample OpenCV code with your explanations. If with words is hard to describe something do not hesitate to add in a reasonable size image, to overcome this issue. When you present OpenCV functionality it's a good idea to give a link to the used OpenCV data structure or function. Because the OpenCV tutorials and reference manual are in separate PDF files it is not possible to make this link work for the PDF format. Therefore, we use here only web page links to the **opencv.itseez.com** website. The OpenCV functions and data structures may be used for multiple tasks. Nevertheless, we want to avoid that every users creates its own reference to a commonly used function. So for this we use the global link collection of *Sphinx*. This is defined in the file:`opencv/doc/conf.py` configuration file. Open it and go all the way down to the last entry: .. code-block:: py # ---- External links for tutorials ----------------- extlinks = { 'huivideo' : ('http://opencv.itseez.com/modules/highgui/doc/reading_and_writing_images_and_video.html#%s', None) } In short here we defined a new **huivideo** directive that refers to an external webpage link. Its usage is: .. code-block:: rst A sample function of the highgui modules image write and read page is the :huivideo:`imread() function `. Which turns to: A sample function of the highgui modules image write and read page is the :huivideo:`imread() function `. The argument you give between the <> will be put in place of the ``%s`` in the upper definition, and as the link will anchor to the correct function. To find out the anchor of a given function just open up a web page, search for the function and click on it. In the address bar it should appear like: ``http://opencv.itseez.com/modules/highgui/doc/reading_and_writing_images_and_video.html#imread`` . Look here for the name of the directives for each page of the OpenCV reference manual. If none present for one of them feel free to add one for it. For formulas you can add LATEX code that will translate in the web pages into images. You do this by using the *math* directive. A usage tip: .. code-block:: latex .. math:: MSE = \frac{1}{c*i*j} \sum{(I_1-I_2)^2} That after build turns into: .. math:: MSE = \frac{1}{c*i*j} \sum{(I_1-I_2)^2} You can even use it inline as ``:math:` MSE = \frac{1}{c*i*j} \sum{(I_1-I_2)^2}``` that turns into :math:`MSE = \frac{1}{c*i*j} \sum{(I_1-I_2)^2}`. If you use some crazy LATEX library extension you need to add those to the ones to use at build time. Look into the file:`opencv/doc/conf.py` configuration file for more information on this. + Results. Well, here depending on your program show one of more of the following: - Console outputs by using the code block directive. - Output images. - Runtime videos, visualization. For this use your favorite screens capture software. `Camtasia Studio `_ certainly is one of the better choices, however their prices are out of this world. `CamStudio `_ is a free alternative, but less powerful. If you do a video you can upload it to YouTube and then use the raw directive with HTML option to embed it into the generated web page: .. code-block:: rst You may observe a runtime instance of this on the `YouTube here `_. .. raw:: html
    This results in the text and video: You may observe a runtime instance of this on the `YouTube here `_. .. raw:: html
    When these aren't self-explanatory make sure to throw in a few guiding lines about what and why we can see. + Build the documentation and check for errors or warnings. In the CMake make sure you check or pass the option for building documentation. Then simply build the **docs** project for the PDF file and the **docs_html** project for the web page. Read the output of the build and check for errors/warnings for what you have added. This is also the time to observe and correct any kind of *not so good looking* parts. Remember to keep clean our build logs. + Read again your tutorial and check for both programming and spelling errors. If found any, please correct them. Take home the pride and joy of a job well done! =============================================== Once you are done contact me or dr. Gary Bradski with the tutorial. We may submit the tutorial ourselves to the trunk branch of our repository or ask you to do so. Now, to see your work **live** you may need to wait some time. The PDFs are updated usually at the launch of a new OpenCV version. The web pages are a little more diverse. They are automatically rebuilt in each evening. However, the **opencv.itseez.com** website contains only the most recent **stable branch** of OpenCV. Currently this is 2.3. When we add something new (like a tutorial) that first goes to the **trunk branch** of our repository. A build of this you may find on the **opencv.itseez.com/trunk** website. Although, we try to make a build every night occasionally we might freeze any of the branches to fix upcoming issues.

Of course, delete the -delete- parts of that e-mail address. \ No newline at end of file +.. _howToWriteTutorial: How to write a tutorial for OpenCV? *********************************** Okay, so assume you have just finished a project of yours implementing something based on OpenCV and you want to present/share it with the community. Luckily, OpenCV is an *open source project*. This means that in theory anyone has access to the full source code and may extend it. While making a robust and practical library (like OpenCV) is great, the success of a library also depends on how user friendly it is. To improve on this aspect, the OpenCV team has already been listening to user feedback from its :opencv_group:`Yahoo user group <>` and by making samples you can find in the source directories sample folder. The addition of the tutorials (in both online and PDF format) is an extension of these efforts. Goal ==== .. _reST: http://docutils.sourceforge.net/rst.html .. |reST| replace:: reStructuredText .. |Sphinx| replace:: Sphinx .. _Sphinx: http://sphinx.pocoo.org/ The tutorials are just as an important part of the library as the implementation of those crafty data structures and algorithms you can find in OpenCV. Therefore, the source codes for the tutorials are part of the library. And yes, I meant source codes. The reason for this formulation is that the tutorials are written by using the |Sphinx|_ documentation generation system. This is based on the popular python documentation system called |reST|_ (reST). ReStructuredText is a really neat language that by using a few simple conventions (indentation, directives) and emulating old school e-mail writing techniques (text only) tries to offer a simple way to create and edit documents. Sphinx extends this with some new features and creates the resulting document in both HTML (for web) and PDF (for offline usage) format. Usually, an OpenCV tutorial has the following parts: 1. A source code demonstration of an OpenCV feature: a. One or more CPP, Python, Java or other type of files depending for what OpenCV offers support and for what language you make the tutorial. #. Occasionaly, input resource files required for running your tutorials application. #. A table of content entry (so people may easily find the tutorial): a. Adding your stuff to the tutorials table of content (**reST** file). #. Add an image file near the TOC entry. #. The content of the tutorial itself: a. The **reST** text of the tutorial #. Images following the idea that "*A picture is worth a thousand words*". #. For more complex demonstrations you may create a video. As you can see you will need at least some basic knowledge of the *reST* system in order to complete the task at hand with success. However, don't worry *reST* (and *Sphinx*) was made with simplicity in mind. It is easy to grasp its basics. I found that the `OpenAlea documentations introduction on this subject `_ (or the `Thomas Cokelaer one `_ ) should enough for this. If for some directive or feature you need a more in-depth description look it up in the official |reST|_ help files or at the |Sphinx|_ documentation. In our world achieving some tasks is possible in multiple ways. However, some of the roads to take may have obvious or hidden advantages over others. Then again, in some other cases it may come down to just simple user preference. Here, I'll present how I decided to write the tutorials, based on my personal experience. If for some of them you know a better solution and you can back it up feel free to use that. I've nothing against it, as long as it gets the job done in an elegant fashion. Now the best would be if you could make the integration yourself. For this you need first to have the source code. I recommend following the guides for your operating system on acquiring OpenCV sources. For Linux users look :ref:`here ` and for :ref:`Windows here `. You must also install python and sphinx with its dependencies in order to be able to build the documentation. Once you have downloaded the repository to your hard drive you can take a look in the OpenCV directory to make sure you have both the samples and doc folder present. Anyone may download the trunk source files from :file:`git://code.opencv.org/opencv.git` . Nevertheless, not everyone has upload (commit/submit) rights. This is to protect the integrity of the library. If you plan doing more than one tutorial, and would like to have an account with commit user rights you should first register an account at http://code.opencv.org/ and then contact dr. Gary Bradski at -delete-bradski@-delete-willowgarage.com. Otherwise, you can just send the resulting files to us via the :opencv_group:`Yahoo user group <>` or to me at -delete-bernat@-delete-primeranks.net and I'll add it. If you have questions, suggestions or constructive critics I will gladly listen to them. If you send it to the OpenCV group please tag its subject with a **[Tutorial]** entry. Format the Source Code ====================== Before I start this let it be clear: the main goal is to have a working sample code. However, for your tutorial to be of a top notch quality you should follow a few guide lines I am going to present here. In case you have an application by using the older interface (with *IplImage*, *CVMat*, *cvLoadImage* and such) consider migrating it to the new C++ interface. The tutorials are intended to be an up to date help for our users. And as of OpenCV 2 the OpenCV emphasis on using the less error prone and clearer C++ interface. Therefore, if possible please convert your code to the C++ interface. For this it may help to read the :ref:`InteroperabilityWithOpenCV1` tutorial. However, once you have an OpenCV 2 working code, then you should make your source code snippet as easy to read as possible. Here're a couple of advices for this: .. container:: enumeratevisibleitemswithsquare + Add a standard output with the description of what your program does. Keep it short and yet, descriptive. This output is at the start of the program. In my example files this usually takes the form of a *help* function containing the output. This way both the source file viewer and application runner can see what all is about in your sample. Here's an instance of this: .. code-block:: cpp void help() { cout << "--------------------------------------------------------------------------" << endl << "This program shows how to write video files. You can extract the R or G or B color channel " << " of the input video. You can choose to use the source codec (Y) or select a custom one. (N)"<< endl << "Usage:" << endl << "./video-write inputvideoName [ R | G | B] [Y | N]" << endl << "--------------------------------------------------------------------------" << endl << endl; } // ... int main(int argc, char *argv[], char *window_name) { help(); // here comes the actual source code } Additionally, finalize the description with a short usage guide. This way the user will know how to call your programs, what leads us to the next point. + Prefer command line argument controlling instead of hard coded one. If your program has some variables that may be changed use command line arguments for this. The tutorials, can be a simple try-out ground for the user. If you offer command line controlling for the input image (for example), then you offer the possibility for the user to try it out with his/her own images, without the need to mess in the source code. In the upper example you can see that the input image, channel and codec selection may all be changed from the command line. Just compile the program and run it with your own input arguments. + Be as verbose as possible. There is no shame in filling the source code with comments. This way the more advanced user may figure out what's happening right from the sample code. This advice goes for the output console too. Specify to the user what's happening. Never leave the user hanging there and thinking on: "Is this program now crashing or just doing some computationally intensive task?." So, if you do a training task that may take some time, make sure you print out a message about this before starting and after finishing it. + Throw out unnecessary stuff from your source code. This is a warning to not take the previous point too seriously. Balance is the key. If it's something that can be done in a fewer lines or simpler than that's the way you should do it. Nevertheless, if for some reason you have such sections notify the user why you have chosen to do so. Keep the amount of information as low as possible, while still getting the job done in an elegant way. + Put your sample file into the :file:`opencv/samples/cpp/tutorial_code/sectionName` folder. If you write a tutorial for other languages than cpp, then change that part of the path. Before completing this you need to decide that to what section (module) does your tutorial goes. Think about on what module relies most heavily your code and that is the one to use. If the answer to this question is more than one modules then the *general* section is the one to use. For finding the *opencv* directory open up your file system and navigate where you downloaded our repository. + If the input resources are hard to acquire for the end user consider adding a few of them to the :file:`opencv/samples/cpp/tutorial_code/images`. Make sure that who reads your code can try it out! Add the TOC entry ================= For this you will need to know some |reST|_. There is no going around this. |reST|_ files have **rst** extensions. However, these are simple text files. Use any text editor you like. Finding a text editor that offers syntax highlighting for |reST|_ was quite a challenge at the time of writing this tutorial. In my experience, `Intype `_ is a solid option on Windows, although there is still place for improvement. Adding your source code to a table of content is important for multiple reasons. First and foremost this will allow for the user base to find your tutorial from our websites tutorial table of content. Secondly, if you omit this *Sphinx* will throw a warning that your tutorial file isn't part of any TOC tree entry. And there is nothing more than the developer team hates than an ever increasing warning/error list for their builds. *Sphinx* also uses this to build up the previous-back-up buttons on the website. Finally, omitting this step will lead to that your tutorial will **not** be added to the PDF version of the tutorials. Navigate to the :file:`opencv/doc/tutorials/section/table_of_content_section` folder (where the section is the module to which you're adding the tutorial). Open the *table_of_content_section* file. Now this may have two forms. If no prior tutorials are present in this section that there is a template message about this and has the following form: .. code-block:: rst .. _Table-Of-Content-Section: Section title ----------------------------------------------------------- Description about the section. .. include:: ../../definitions/noContent.rst .. raw:: latex \pagebreak The first line is a reference to the section title in the reST system. The section title will be a link and you may refer to it via the ``:ref:`` directive. The *include* directive imports the template text from the definitions directories *noContent.rst* file. *Sphinx* does not creates the PDF from scratch. It does this by first creating a latex file. Then creates the PDF from the latex file. With the *raw* directive you can directly add to this output commands. Its unique argument is for what kind of output to add the content of the directive. For the PDFs it may happen that multiple sections will overlap on a single page. To avoid this at the end of the TOC we add a *pagebreak* latex command, that hints to the LATEX system that the next line should be on a new page. If you have one of this, try to transform it to the following form: .. include:: ../../definitions/tocDefinitions.rst .. code-block:: rst .. _Table-Of-Content-Section: Section title ----------------------------------------------------------- .. include:: ../../definitions/tocDefinitions.rst + .. tabularcolumns:: m{100pt} m{300pt} .. cssclass:: toctableopencv =============== ====================================================== |MatBasicIma| **Title:** :ref:`matTheBasicImageContainer` *Compatibility:* > OpenCV 2.0 *Author:* |Author_BernatG| You will learn how to store images in the memory and how to print out their content to the console. =============== ===================================================== .. |MatBasicIma| image:: images/matTheBasicImageStructure.jpg :height: 90pt :width: 90pt .. raw:: latex \pagebreak .. toctree:: :hidden: ../mat - the basic image container/mat - the basic image container If this is already present just add a new section of the content between the include and the raw directives (excluding those lines). Here you'll see a new include directive. This should be present only once in a TOC tree and the reST file contains the definitions of all the authors contributing to the OpenCV tutorials. We are a multicultural community and some of our name may contain some funky characters. However, reST **only supports** ANSI characters. Luckily we can specify Unicode characters with the *unicode* directive. Doing this for all of your tutorials is a troublesome procedure. Therefore, the tocDefinitions file contains the definition of your author name. Add it here once and afterwards just use the replace construction. For example here's the definition for my name: .. code-block:: rst .. |Author_BernatG| unicode:: Bern U+00E1 t U+0020 G U+00E1 bor The ``|Author_BernatG|`` is the text definitions alias. I can use later this to add the definition, like I've done in the TOCs *Author* part. After the ``::`` and a space you start the definition. If you want to add an UNICODE character (non-ASCI) leave an empty space and specify it in the format U+(UNICODE code). To find the UNICODE code of a character I recommend using the `FileFormat `_ websites service. Spaces are trimmed from the definition, therefore we add a space by its UNICODE character (U+0020). Until the *raw* directive what you can see is a TOC tree entry. Here's how a TOC entry will look like: + .. tabularcolumns:: m{100pt} m{300pt} .. cssclass:: toctableopencv =============== ====================================================== |MatBasicIma| **Title:** :ref:`matTheBasicImageContainer` *Compatibility:* > OpenCV 2.0 *Author:* |Author_BernatG| You will learn how to store images in the memory and how to print out their content to the console. =============== ====================================================== .. |MatBasicIma| image:: images/matTheBasicImageStructure.jpg :height: 90pt :width: 90pt As you can see we have an image to the left and a description box to the right. To create two boxes we use a table with two columns and a single row. In the left column is the image and in the right one the description. However, the image directive is way too long to fit in a column. Therefore, we need to use the substitution definition system. We add this definition after the TOC tree. All images for the TOC tree are to be put in the images folder near its |reST|_ file. We use the point measurement system because we are also creating PDFs. PDFs are printable documents, where there is no such thing that pixels (px), just points (pt). And while generally space is no problem for web pages (we have monitors with **huge** resolutions) the size of the paper (A4 or letter) is constant and will be for a long time in the future. Therefore, size constrains come in play more like for the PDF, than the generated HTML code. Now your images should be as small as possible, while still offering the intended information for the user. Remember that the tutorial will become part of the OpenCV source code. If you add large images (that manifest in form of large image size) it will just increase the size of the repository pointlessly. If someone wants to download it later, its download time will be that much longer. Not to mention the larger PDF size for the tutorials and the longer load time for the web pages. In terms of pixels a TOC image should not be larger than 120 X 120 pixels. Resize your images if they are larger! .. note:: If you add a larger image and specify a smaller image size, *Sphinx* will not resize that. At build time will add the full size image and the resize will be done by your browser after the image is loaded. A 120 X 120 image is somewhere below 10KB. If you add a 110KB image, you have just pointlessly added a 100KB extra data to transfer over the internet for every user! Generally speaking you shouldn't need to specify your images size (excluding the TOC entries). If no such is found *Sphinx* will use the size of the image itself (so no resize occurs). Then again if for some reason you decide to specify a size that should be the **width** of the image rather than its height. The reason for this again goes back to the PDFs. On a PDF page the height is larger than the width. In the PDF the images will not be resized. If you specify a size that does not fit in the page, then what does not fits in **will be cut off**. When creating your images for your tutorial you should try to keep the image widths below 500 pixels, and calculate with around 400 point page width when specifying image widths. The image format depends on the content of the image. If you have some complex scene (many random like colors) then use *jpg*. Otherwise, prefer using *png*. They are even some tools out there that optimize the size of *PNG* images, such as `PNGGauntlet `_. Use them to make your images as small as possible in size. Now on the right side column of the table we add the information about the tutorial: .. container:: enumeratevisibleitemswithsquare + In the first line it is the title of the tutorial. However, there is no need to specify it explicitly. We use the reference system. We'll start up our tutorial with a reference specification, just like in case of this TOC entry with its `` .. _Table-Of-Content-Section:`` . If after this you have a title (pointed out by the following line of -), then Sphinx will replace the ``:ref:`Table-Of-Content-Section``` directive with the tile of the section in reference form (creates a link in web page). Here's how the definition looks in my case: .. code-block:: rst .. _matTheBasicImageContainer: Mat - The Basic Image Container ******************************* Note, that according to the |reST|_ rules the * should be as long as your title. + Compatibility. What version of OpenCV is required to run your sample code. + Author. Use the substitution markup of |reST|_. + A short sentence describing the essence of your tutorial. Now before each TOC entry you need to add the three lines of: .. code-block:: cpp + .. tabularcolumns:: m{100pt} m{300pt} .. cssclass:: toctableopencv The plus sign (+) is to enumerate tutorials by using bullet points. So for every TOC entry we have a corresponding bullet point represented by the +. Sphinx is highly indenting sensitive. Indentation is used to express from which point until to which point does a construction last. Un-indentation means end of that construction. So to keep all the bullet points to the same group the following TOC entries (until the next +) should be indented by two spaces. Here, I should also mention that **always** prefer using spaces instead of tabs. Working with only spaces makes possible that if we both use monotype fonts we will see the same thing. Tab size is text editor dependent and as should be avoided. *Sphinx* translates all tabs into 8 spaces before interpreting it. It turns out that the automatic formatting of both the HTML and PDF(LATEX) system messes up our tables. Therefore, we need to help them out a little. For the PDF generation we add the ``.. tabularcolumns:: m{100pt} m{300pt}`` directive. This means that the first column should be 100 points wide and middle aligned. For the HTML look we simply name the following table of a *toctableopencv* class type. Then, we can modify the look of the table by modifying the CSS of our web page. The CSS definitions go into the :file:`opencv/doc/_themes/blue/static/default.css_t` file. .. code-block:: css .toctableopencv { width: 100% ; table-layout: fixed; } .toctableopencv colgroup col:first-child { width: 100pt !important; max-width: 100pt !important; min-width: 100pt !important; } .toctableopencv colgroup col:nth-child(2) { width: 100% !important; } However, you should not need to modify this. Just add these three lines (plus keep the two space indentation) for all TOC entries you add. At the end of the TOC file you'll find: .. code-block:: rst .. raw:: latex \pagebreak .. toctree:: :hidden: ../mat - the basic image container/mat - the basic image container The page break entry comes for separating sections and should be only one in a TOC tree |reST|_ file. Finally, at the end of the TOC tree we need to add our tutorial to the *Sphinx* TOC tree system. *Sphinx* will generate from this the previous-next-up information for the HTML file and add items to the PDF according to the order here. By default this TOC tree directive generates a simple table of contents. However, we already created a fancy looking one so we no longer need this basic one. Therefore, we add the *hidden* option to do not show it. The path is of a relative type. We step back in the file system and then go into the :file:`mat - the basic image container` directory for the :file:`mat - the basic image container.rst` file. Putting out the *rst* extension for the file is optional. Write the tutorial ================== Create a folder with the name of your tutorial. Preferably, use small letters only. Then create a text file in this folder with *rst* extension and the same name. If you have images for the tutorial create an :file:`images` folder and add your images there. When creating your images follow the guidelines described in the previous part! Now here's our recommendation for the structure of the tutorial (although, remember that this is not carved in the stone; if you have a better idea, use it!): .. container:: enumeratevisibleitemswithsquare + Create the reference point and the title. .. code-block:: rst .. _matTheBasicImageContainer: Mat - The Basic Image Container ******************************* You start the tutorial by specifying a reference point by the ``.. _matTheBasicImageContainer:`` and then its title. The name of the reference point should be a unique one over the whole documentation. Therefore, do not use general names like *tutorial1*. Use the * character to underline the title for its full width. The subtitles of the tutorial should be underlined with = charachter. + Goals. You start your tutorial by specifying what you will present. You can also enumerate the sub jobs to be done. For this you can use a bullet point construction. There is a single configuration file for both the reference manual and the tutorial documentation. In the reference manuals at the argument enumeration we do not want any kind of bullet point style enumeration. Therefore, by default all the bullet points at this level are set to do not show the dot before the entries in the HTML. You can override this by putting the bullet point in a container. I've defined a square type bullet point view under the name *enumeratevisibleitemswithsquare*. The CSS style definition for this is again in the :file:`opencv\doc\_themes\blue\static\default.css_t` file. Here's a quick example of using it: .. code-block:: rst .. container:: enumeratevisibleitemswithsquare + Create the reference point and the title. + Second entry + Third entry Note that you need the keep the indentation of the container directive. Directive indentations are always three (3) spaces. Here you may even give usage tips for your sample code. + Source code. Present your samples code to the user. It's a good idea to offer a quick download link for the HTML page by using the *download* directive and pointing out where the user may find your source code in the file system by using the *file* directive: .. code-block:: rst Text :file:`samples/cpp/tutorial_code/highgui/video-write/` folder of the OpenCV source library or :download:`text to appear in the webpage <../../../../samples/cpp/tutorial_code/HighGUI/video-write/video-write.cpp>`. For the download link the path is a relative one, hence the multiple back stepping operations (..). Then you can add the source code either by using the *code block* directive or the *literal include* one. In case of the code block you will need to actually add all the source code text into your |reST|_ text and also apply the required indentation: .. code-block:: rst .. code-block:: cpp int i = 0; l = ++j; The only argument of the directive is the language used (here CPP). Then you add the source code into its content (meaning one empty line after the directive) by keeping the indentation of the directive (3 spaces). With the *literal include* directive you do not need to add the source code of the sample. You just specify the sample and *Sphinx* will load it for you, during build time. Here's an example usage: .. code-block:: rst .. literalinclude:: ../../../../samples/cpp/tutorial_code/HighGUI/video-write/video-write.cpp :language: cpp :linenos: :tab-width: 4 :lines: 1-8, 21-22, 24- After the directive you specify a relative path to the file from what to import. It has four options: the language to use, if you add the ``:linenos:`` the line numbers will be shown, you can specify the tab size with the ``:tab-width:`` and you do not need to load the whole file, you can show just the important lines. Use the *lines* option to do not show redundant information (such as the *help* function). Here basically you specify ranges, if the second range line number is missing than that means that until the end of the file. The ranges specified here do no need to be in an ascending order, you may even reorganize the structure of how you want to show your sample inside the tutorial. + The tutorial. Well here goes the explanation for why and what have you used. Try to be short, clear, concise and yet a thorough one. There's no magic formula. Look into a few already made tutorials and start out from there. Try to mix sample OpenCV code with your explanations. If with words is hard to describe something do not hesitate to add in a reasonable size image, to overcome this issue. When you present OpenCV functionality it's a good idea to give a link to the used OpenCV data structure or function. Because the OpenCV tutorials and reference manual are in separate PDF files it is not possible to make this link work for the PDF format. Therefore, we use here only web page links to the **opencv.itseez.com** website. The OpenCV functions and data structures may be used for multiple tasks. Nevertheless, we want to avoid that every users creates its own reference to a commonly used function. So for this we use the global link collection of *Sphinx*. This is defined in the file:`opencv/doc/conf.py` configuration file. Open it and go all the way down to the last entry: .. code-block:: py # ---- External links for tutorials ----------------- extlinks = { 'hgvideo' : ('http://opencv.itseez.com/modules/highgui/doc/reading_and_writing_images_and_video.html#%s', None) } In short here we defined a new **hgvideo** directive that refers to an external webpage link. Its usage is: .. code-block:: rst A sample function of the highgui modules image write and read page is the :hgvideo:`imread() function `. Which turns to: A sample function of the highgui modules image write and read page is the :hgvideo:`imread() function `. The argument you give between the <> will be put in place of the ``%s`` in the upper definition, and as the link will anchor to the correct function. To find out the anchor of a given function just open up a web page, search for the function and click on it. In the address bar it should appear like: ``http://opencv.itseez.com/modules/highgui/doc/reading_and_writing_images_and_video.html#imread`` . Look here for the name of the directives for each page of the OpenCV reference manual. If none present for one of them feel free to add one for it. For formulas you can add LATEX code that will translate in the web pages into images. You do this by using the *math* directive. A usage tip: .. code-block:: latex .. math:: MSE = \frac{1}{c*i*j} \sum{(I_1-I_2)^2} That after build turns into: .. math:: MSE = \frac{1}{c*i*j} \sum{(I_1-I_2)^2} You can even use it inline as ``:math:` MSE = \frac{1}{c*i*j} \sum{(I_1-I_2)^2}``` that turns into :math:`MSE = \frac{1}{c*i*j} \sum{(I_1-I_2)^2}`. If you use some crazy LATEX library extension you need to add those to the ones to use at build time. Look into the file:`opencv/doc/conf.py` configuration file for more information on this. + Results. Well, here depending on your program show one of more of the following: - Console outputs by using the code block directive. - Output images. - Runtime videos, visualization. For this use your favorite screens capture software. `Camtasia Studio `_ certainly is one of the better choices, however their prices are out of this world. `CamStudio `_ is a free alternative, but less powerful. If you do a video you can upload it to YouTube and then use the raw directive with HTML option to embed it into the generated web page: .. code-block:: rst You may observe a runtime instance of this on the `YouTube here `_. .. raw:: html
    This results in the text and video: You may observe a runtime instance of this on the `YouTube here `_. .. raw:: html
    When these aren't self-explanatory make sure to throw in a few guiding lines about what and why we can see. + Build the documentation and check for errors or warnings. In the CMake make sure you check or pass the option for building documentation. Then simply build the **docs** project for the PDF file and the **docs_html** project for the web page. Read the output of the build and check for errors/warnings for what you have added. This is also the time to observe and correct any kind of *not so good looking* parts. Remember to keep clean our build logs. + Read again your tutorial and check for both programming and spelling errors. If found any, please correct them. Take home the pride and joy of a job well done! =============================================== Once you are done contact me or dr. Gary Bradski with the tutorial. We may submit the tutorial ourselves to the trunk branch of our repository or ask you to do so. Now, to see your work **live** you may need to wait some time. The PDFs are updated usually at the launch of a new OpenCV version. The web pages are a little more diverse. They are automatically rebuilt in each evening. However, the **opencv.itseez.com** website contains only the most recent **stable branch** of OpenCV. Currently this is 2.3. When we add something new (like a tutorial) that first goes to the **trunk branch** of our repository. A build of this you may find on the **opencv.itseez.com/trunk** website. Although, we try to make a build every night occasionally we might freeze any of the branches to fix upcoming issues.

When the breakpoint is hit, the program is paused and Visual Studio displays a yellow instruction pointer at the breakpoint: + +.. image:: images/breakpoint.png + +Now you can inspect the state of you program. For example, you can bring up the *Locals* window (:menuselection:`Debug --> Windows --> Locals`), which will show the names and values of the variables in the current scope: + +.. image:: images/vs_locals.png + +Note that the built-in *Locals* window will display text only. This is where the Image Watch plug-in comes in. Image Watch is like another *Locals* window, but with an image viewer built into it. To bring up Image Watch, select :menuselection:`View --> Other Windows --> Image Watch`. Like Visual Studio's *Locals* window, Image Watch can dock to the Visual Studio IDE. Also, Visual Studio will remember whether you had Image Watch open, and where it was located between debugging sessions. This means you only have to do this once--the next time you start debugging, Image Watch will be back where you left it. Here's what the docked Image Watch window looks like at our breakpoint: + +.. image:: images/toolwindow.jpg + :height: 320pt + +The radio button at the top left (*Locals/Watch*) selects what is shown in the *Image List* below: *Locals* lists all OpenCV image objects in the current scope (this list is automatically populated). *Watch* shows image expressions that have been pinned for continuous inspection (not described here, see `Image Watch documentation `_ for details). The image list shows basic information such as width, height, number of channels, and, if available, a thumbnail. In our example, the image list contains our two local image variables, *input* and *edges*. + +If an image has a thumbnail, left-clicking on that image will select it for detailed viewing in the *Image Viewer* on the right. The viewer lets you pan (drag mouse) and zoom (mouse wheel). It also displays the pixel coordinate and value at the current mouse position. + +.. image:: images/viewer.jpg + :height: 160pt + +Note that the second image in the list, *edges*, is shown as "invalid". This indicates that some data members of this image object have corrupt or invalid values (for example, a negative image width). This is expected at this point in the program, since the C++ constructor for *edges* has not run yet, and so its members have undefined values (in debug mode they are usually filled with "0xCD" bytes). + +From here you can single-step through your code (:menuselection:`Debug->Step Over`, or press *F10*) and watch the pixels change: if you step once, over the *Mat edges;* statement, the *edges* image will change from "invalid" to "empty", which means that it is now in a valid state (default constructed), even though it has not been initialized yet (using *cv::Mat::create()*, for example). If you make one more step over the *cv::Canny()* call, you will see a thumbnail of the edge image appear in the image list. + +Now assume you want to do a visual sanity check of the *cv::Canny()* implementation. Bring the *edges* image into the viewer by selecting it in the *Image List* and zoom into a region with a clearly defined edge: + +.. image:: images/edges_zoom.png + :height: 160pt + +Right-click on the *Image Viewer* to bring up the view context menu and enable :menuselection:`Link Views` (a check box next to the menu item indicates whether the option is enabled). + +.. image:: images/viewer_context_menu.png + :height: 120pt + +The :menuselection:`Link Views` feature keeps the view region fixed when flipping between images of the same size.

OpenCV is released under a BSD license so it is used in academic projects and commercial products alike. OpenCV 2.4 now comes with the very new :ocv:class:`FaceRecognizer` class for face recognition, so you can start experimenting with face recognition right away. This document is the guide I've wished for, when I was working myself into face recognition. It shows you how to perform face recognition with :ocv:class:`FaceRecognizer` in OpenCV (with full source code listings) and gives you an introduction into the algorithms behind. I'll also show how to create the visualizations you can find in many publications, because a lot of people asked for. diff --git a/modules/contrib/doc/facerec/src/CMakeLists.txt b/modules/contrib/doc/facerec/src/CMakeLists.txt index 10720048c..e56762ea4 100644 --- a/modules/contrib/doc/facerec/src/CMakeLists.txt +++ b/modules/contrib/doc/facerec/src/CMakeLists.txt @@ -6,7 +6,7 @@ project(facerec_cpp_samples) #SET(OpenCV_DIR /path/to/your/opencv/installation) #

- The n-dimensional matrix class. - - The class represents an n-dimensional dense numerical array that can act as - a matrix, image, optical flow map, 3-focal tensor etc. - It is very similar to CvMat and CvMatND types from earlier versions of OpenCV, - and similarly to those types, the matrix can be multi-channel. It also fully supports ROI mechanism. - - There are many different ways to create cv::Mat object. Here are the some popular ones: -
      -
    • using cv::Mat::create(nrows, ncols, type) method or - the similar constructor cv::Mat::Mat(nrows, ncols, type[, fill_value]) constructor. - A new matrix of the specified size and specifed type will be allocated. - "type" has the same meaning as in cvCreateMat function, - e.g. CV_8UC1 means 8-bit single-channel matrix, CV_32FC2 means 2-channel (i.e. complex) - floating-point matrix etc: - - \code - // make 7x7 complex matrix filled with 1+3j. - cv::Mat M(7,7,CV_32FC2,Scalar(1,3)); - // and now turn M to 100x60 15-channel 8-bit matrix. - // The old content will be deallocated - M.create(100,60,CV_8UC(15)); - \endcode - - As noted in the introduction of this chapter, Mat::create() - will only allocate a new matrix when the current matrix dimensionality - or type are different from the specified. - -
    • by using a copy constructor or assignment operator, where on the right side it can - be a matrix or expression, see below. Again, as noted in the introduction, - matrix assignment is O(1) operation because it only copies the header - and increases the reference counter. cv::Mat::clone() method can be used to get a full - (a.k.a. deep) copy of the matrix when you need it. - -
    • by constructing a header for a part of another matrix. It can be a single row, single column, - several rows, several columns, rectangular region in the matrix (called a minor in algebra) or - a diagonal. Such operations are also O(1), because the new header will reference the same data. - You can actually modify a part of the matrix using this feature, e.g. - - \code - // add 5-th row, multiplied by 3 to the 3rd row - M.row(3) = M.row(3) + M.row(5)*3; - - // now copy 7-th column to the 1-st column - // M.col(1) = M.col(7); // this will not work - Mat M1 = M.col(1); - M.col(7).copyTo(M1); - - // create new 320x240 image - cv::Mat img(Size(320,240),CV_8UC3); - // select a roi - cv::Mat roi(img, Rect(10,10,100,100)); - // fill the ROI with (0,255,0) (which is green in RGB space); - // the original 320x240 image will be modified - roi = Scalar(0,255,0); - \endcode - - Thanks to the additional cv::Mat::datastart and cv::Mat::dataend members, it is possible to - compute the relative sub-matrix position in the main "container" matrix using cv::Mat::locateROI(): - - \code - Mat A = Mat::eye(10, 10, CV_32S); - // extracts A columns, 1 (inclusive) to 3 (exclusive). - Mat B = A(Range::all(), Range(1, 3)); - // extracts B rows, 5 (inclusive) to 9 (exclusive). - // that is, C ~ A(Range(5, 9), Range(1, 3)) - Mat C = B(Range(5, 9), Range::all()); - Size size; Point ofs; - C.locateROI(size, ofs); - // size will be (width=10,height=10) and the ofs will be (x=1, y=5) - \endcode - - As in the case of whole matrices, if you need a deep copy, use cv::Mat::clone() method - of the extracted sub-matrices. - -
    • by making a header for user-allocated-data. It can be useful for -
        -
      1. processing "foreign" data using OpenCV (e.g. when you implement - a DirectShow filter or a processing module for gstreamer etc.), e.g. - - \code - void process_video_frame(const unsigned char* pixels, - int width, int height, int step) - { - cv::Mat img(height, width, CV_8UC3, pixels, step); - cv::GaussianBlur(img, img, cv::Size(7,7), 1.5, 1.5); - } - \endcode - -
      2. for quick initialization of small matrices and/or super-fast element access - - \code - double m[3][3] = {{a, b, c}, {d, e, f}, {g, h, i}}; - cv::Mat M = cv::Mat(3, 3, CV_64F, m).inv(); - \endcode -
      - - partial yet very common cases of this "user-allocated data" case are conversions - from CvMat and IplImage to cv::Mat. For this purpose there are special constructors - taking pointers to CvMat or IplImage and the optional - flag indicating whether to copy the data or not. - - Backward conversion from cv::Mat to CvMat or IplImage is provided via cast operators - cv::Mat::operator CvMat() an cv::Mat::operator IplImage(). - The operators do not copy the data. - - - \code - IplImage* img = cvLoadImage("greatwave.jpg", 1); - Mat mtx(img); // convert IplImage* -> cv::Mat - CvMat oldmat = mtx; // convert cv::Mat -> CvMat - CV_Assert(oldmat.cols == img->width && oldmat.rows == img->height && - oldmat.data.ptr == (uchar*)img->imageData && oldmat.step == img->widthStep); - \endcode - -
    • by using MATLAB-style matrix initializers, cv::Mat::zeros(), cv::Mat::ones(), cv::Mat::eye(), e.g.: - - \code - // create a double-precision identity martix and add it to M. - M += Mat::eye(M.rows, M.cols, CV_64F); - \endcode - -
    • by using comma-separated initializer: - - \code - // create 3x3 double-precision identity matrix - Mat M = (Mat_(3,3) << 1, 0, 0, 0, 1, 0, 0, 0, 1); - \endcode - - here we first call constructor of cv::Mat_ class (that we describe further) with the proper matrix, - and then we just put "<<" operator followed by comma-separated values that can be constants, - variables, expressions etc. Also, note the extra parentheses that are needed to avoid compiler errors. - -
    - - Once matrix is created, it will be automatically managed by using reference-counting mechanism - (unless the matrix header is built on top of user-allocated data, - in which case you should handle the data by yourself). - The matrix data will be deallocated when no one points to it; - if you want to release the data pointed by a matrix header before the matrix destructor is called, - use cv::Mat::release(). - - The next important thing to learn about the matrix class is element access. Here is how the matrix is stored. - The elements are stored in row-major order (row by row). The cv::Mat::data member points to the first element of the first row, - cv::Mat::rows contains the number of matrix rows and cv::Mat::cols - the number of matrix columns. There is yet another member, - cv::Mat::step that is used to actually compute address of a matrix element. cv::Mat::step is needed because the matrix can be - a part of another matrix or because there can some padding space in the end of each row for a proper alignment. - - \image html roi.png - - Given these parameters, address of the matrix element M_{ij} is computed as following: - - addr(M_{ij})=M.data + M.step*i + j*M.elemSize() - - if you know the matrix element type, e.g. it is float, then you can use cv::Mat::at() method: - - addr(M_{ij})=&M.at(i,j) - - (where & is used to convert the reference returned by cv::Mat::at() to a pointer). - if you need to process a whole row of matrix, the most efficient way is to get - the pointer to the row first, and then just use plain C operator []: - - \code - // compute sum of positive matrix elements - // (assuming that M is double-precision matrix) - double sum=0; - for(int i = 0; i < M.rows; i++) - { - const double* Mi = M.ptr(i); - for(int j = 0; j < M.cols; j++) - sum += std::max(Mi[j], 0.); - } - \endcode - - Some operations, like the above one, do not actually depend on the matrix shape, - they just process elements of a matrix one by one (or elements from multiple matrices - that are sitting in the same place, e.g. matrix addition). Such operations are called - element-wise and it makes sense to check whether all the input/output matrices are continuous, - i.e. have no gaps in the end of each row, and if yes, process them as a single long row: - - \code - // compute sum of positive matrix elements, optimized variant - double sum=0; - int cols = M.cols, rows = M.rows; - if(M.isContinuous()) - { - cols *= rows; - rows = 1; - } - for(int i = 0; i < rows; i++) - { - const double* Mi = M.ptr(i); - for(int j = 0; j < cols; j++) - sum += std::max(Mi[j], 0.); - } - \endcode - in the case of continuous matrix the outer loop body will be executed just once, - so the overhead will be smaller, which will be especially noticeable in the case of small matrices. - - Finally, there are STL-style iterators that are smart enough to skip gaps between successive rows: - \code - // compute sum of positive matrix elements, iterator-based variant - double sum=0; - MatConstIterator_ it = M.begin(), it_end = M.end(); - for(; it != it_end; ++it) - sum += std::max(*it, 0.); - \endcode - - The matrix iterators are random-access iterators, so they can be passed - to any STL algorithm, including std::sort(). -*/ -class CV_EXPORTS Mat -{ -public: - //! default constructor - Mat(); - //! constructs 2D matrix of the specified size and type - // (_type is CV_8UC1, CV_64FC3, CV_32SC(12) etc.) - Mat(int rows, int cols, int type); - Mat(Size size, int type); - //! constucts 2D matrix and fills it with the specified value _s. - Mat(int rows, int cols, int type, const Scalar& s); - Mat(Size size, int type, const Scalar& s); - - //! constructs n-dimensional matrix - Mat(int ndims, const int* sizes, int type); - Mat(int ndims, const int* sizes, int type, const Scalar& s); - - //! copy constructor - Mat(const Mat& m); - //! constructor for matrix headers pointing to user-allocated data - Mat(int rows, int cols, int type, void* data, size_t step=AUTO_STEP); - Mat(Size size, int type, void* data, size_t step=AUTO_STEP); - Mat(int ndims, const int* sizes, int type, void* data, const size_t* steps=0); - - //! creates a matrix header for a part of the bigger matrix - Mat(const Mat& m, const Range& rowRange, const Range& colRange=Range::all()); - Mat(const Mat& m, const Rect& roi); - Mat(const Mat& m, const Range* ranges); - //! converts old-style CvMat to the new matrix; the data is not copied by default - Mat(const CvMat* m, bool copyData=false); - //! converts old-style CvMatND to the new matrix; the data is not copied by default - Mat(const CvMatND* m, bool copyData=false); - //! converts old-style IplImage to the new matrix; the data is not copied by default - Mat(const IplImage* img, bool copyData=false); - //! builds matrix from std::vector with or without copying the data - template explicit Mat(const vector<_Tp>& vec, bool copyData=false); - //! builds matrix from cv::Vec; the data is copied by default - template explicit Mat(const Vec<_Tp, n>& vec, bool copyData=true); - //! builds matrix from cv::Matx; the data is copied by default - template explicit Mat(const Matx<_Tp, m, n>& mtx, bool copyData=true); - //! builds matrix from a 2D point - template explicit Mat(const Point_<_Tp>& pt, bool copyData=true); - //! builds matrix from a 3D point - template explicit Mat(const Point3_<_Tp>& pt, bool copyData=true); - //! builds matrix from comma initializer - template explicit Mat(const MatCommaInitializer_<_Tp>& commaInitializer); - - //! download data from GpuMat - explicit Mat(const gpu::GpuMat& m); - - //! destructor - calls release() - ~Mat(); - //! assignment operators - Mat& operator = (const Mat& m); - Mat& operator = (const MatExpr& expr); - - //! returns a new matrix header for the specified row - Mat row(int y) const; - //! returns a new matrix header for the specified column - Mat col(int x) const; - //! ... for the specified row span - Mat rowRange(int startrow, int endrow) const; - Mat rowRange(const Range& r) const; - //! ... for the specified column span - Mat colRange(int startcol, int endcol) const; - Mat colRange(const Range& r) const; - //! ... for the specified diagonal - // (d=0 - the main diagonal, - // >0 - a diagonal from the lower half, - // <0 - a diagonal from the upper half) - Mat diag(int d=0) const; - //! constructs a square diagonal matrix which main diagonal is vector "d" - static Mat diag(const Mat& d); - - //! returns deep copy of the matrix, i.e. the data is copied - Mat clone() const; - //! copies the matrix content to "m". - // It calls m.create(this->size(), this->type()). - void copyTo( OutputArray m ) const; - //! copies those matrix elements to "m" that are marked with non-zero mask elements. - void copyTo( OutputArray m, InputArray mask ) const; - //! converts matrix to another datatype with optional scalng.

Such a sparse array can store elements - of any type that cv::Mat is able to store. "Sparse" means that only non-zero elements - are stored (though, as a result of some operations on a sparse matrix, some of its stored elements - can actually become 0. It's user responsibility to detect such elements and delete them using cv::SparseMat::erase(). - The non-zero elements are stored in a hash table that grows when it's filled enough, - so that the search time remains O(1) in average. Elements can be accessed using the following methods: - -
      -
    1. Query operations: cv::SparseMat::ptr() and the higher-level cv::SparseMat::ref(), - cv::SparseMat::value() and cv::SparseMat::find, for example: - \code - const int dims = 5; - int size[] = {10, 10, 10, 10, 10}; - SparseMat sparse_mat(dims, size, CV_32F); - for(int i = 0; i < 1000; i++) - { - int idx[dims]; - for(int k = 0; k < dims; k++) - idx[k] = rand()%sparse_mat.size(k); - sparse_mat.ref(idx) += 1.f; - } - \endcode - -
    2. Sparse matrix iterators. Like cv::Mat iterators and unlike cv::Mat iterators, the sparse matrix iterators are STL-style, - that is, the iteration is done as following: - \code - // prints elements of a sparse floating-point matrix and the sum of elements. - SparseMatConstIterator_ - it = sparse_mat.begin(), - it_end = sparse_mat.end(); - double s = 0; - int dims = sparse_mat.dims(); - for(; it != it_end; ++it) - { - // print element indices and the element value - const Node* n = it.node(); - printf("(") - for(int i = 0; i < dims; i++) - printf("%3d%c", n->idx[i], i < dims-1 ? ',' : ')'); - printf(": %f\n", *it); - s += *it; - } - printf("Element sum is %g\n", s); - \endcode - If you run this loop, you will notice that elements are enumerated - in no any logical order (lexicographical etc.), - they come in the same order as they stored in the hash table, i.e. semi-randomly. - - You may collect pointers to the nodes and sort them to get the proper ordering. - Note, however, that pointers to the nodes may become invalid when you add more - elements to the matrix; this is because of possible buffer reallocation. - -
    3. A combination of the above 2 methods when you need to process 2 or more sparse - matrices simultaneously, e.g. this is how you can compute unnormalized - cross-correlation of the 2 floating-point sparse matrices: - \code - double crossCorr(const SparseMat& a, const SparseMat& b) - { - const SparseMat *_a = &a, *_b = &b; - // if b contains less elements than a, - // it's faster to iterate through b - if(_a->nzcount() > _b->nzcount()) - std::swap(_a, _b); - SparseMatConstIterator_ it = _a->begin(), - it_end = _a->end(); - double ccorr = 0; - for(; it != it_end; ++it) - { - // take the next element from the first matrix - float avalue = *it; - const Node* anode = it.node(); - // and try to find element with the same index in the second matrix. - // since the hash value depends only on the element index, - // we reuse hashvalue stored in the node - float bvalue = _b->value(anode->idx,&anode->hashval); - ccorr += avalue*bvalue; - } - return ccorr; - } - \endcode -

+ The n-dimensional matrix class. + + The class represents an n-dimensional dense numerical array that can act as + a matrix, image, optical flow map, 3-focal tensor etc. + It is very similar to CvMat and CvMatND types from earlier versions of OpenCV, + and similarly to those types, the matrix can be multi-channel. It also fully supports ROI mechanism. + + There are many different ways to create cv::Mat object. Here are the some popular ones: +
      +
    • using cv::Mat::create(nrows, ncols, type) method or + the similar constructor cv::Mat::Mat(nrows, ncols, type[, fill_value]) constructor. + A new matrix of the specified size and specifed type will be allocated. + "type" has the same meaning as in cvCreateMat function, + e.g. CV_8UC1 means 8-bit single-channel matrix, CV_32FC2 means 2-channel (i.e. complex) + floating-point matrix etc: + + \code + // make 7x7 complex matrix filled with 1+3j. + cv::Mat M(7,7,CV_32FC2,Scalar(1,3)); + // and now turn M to 100x60 15-channel 8-bit matrix. + // The old content will be deallocated + M.create(100,60,CV_8UC(15)); + \endcode + + As noted in the introduction of this chapter, Mat::create() + will only allocate a new matrix when the current matrix dimensionality + or type are different from the specified. + +
    • by using a copy constructor or assignment operator, where on the right side it can + be a matrix or expression, see below. Again, as noted in the introduction, + matrix assignment is O(1) operation because it only copies the header + and increases the reference counter. cv::Mat::clone() method can be used to get a full + (a.k.a. deep) copy of the matrix when you need it. + +
    • by constructing a header for a part of another matrix. It can be a single row, single column, + several rows, several columns, rectangular region in the matrix (called a minor in algebra) or + a diagonal. Such operations are also O(1), because the new header will reference the same data. + You can actually modify a part of the matrix using this feature, e.g. + + \code + // add 5-th row, multiplied by 3 to the 3rd row + M.row(3) = M.row(3) + M.row(5)*3; + + // now copy 7-th column to the 1-st column + // M.col(1) = M.col(7); // this will not work + Mat M1 = M.col(1); + M.col(7).copyTo(M1); + + // create new 320x240 image + cv::Mat img(Size(320,240),CV_8UC3); + // select a roi + cv::Mat roi(img, Rect(10,10,100,100)); + // fill the ROI with (0,255,0) (which is green in RGB space); + // the original 320x240 image will be modified + roi = Scalar(0,255,0); + \endcode + + Thanks to the additional cv::Mat::datastart and cv::Mat::dataend members, it is possible to + compute the relative sub-matrix position in the main "container" matrix using cv::Mat::locateROI(): + + \code + Mat A = Mat::eye(10, 10, CV_32S); + // extracts A columns, 1 (inclusive) to 3 (exclusive). + Mat B = A(Range::all(), Range(1, 3)); + // extracts B rows, 5 (inclusive) to 9 (exclusive). + // that is, C ~ A(Range(5, 9), Range(1, 3)) + Mat C = B(Range(5, 9), Range::all()); + Size size; Point ofs; + C.locateROI(size, ofs); + // size will be (width=10,height=10) and the ofs will be (x=1, y=5) + \endcode + + As in the case of whole matrices, if you need a deep copy, use cv::Mat::clone() method + of the extracted sub-matrices. + +
    • by making a header for user-allocated-data. It can be useful for +
        +
      1. processing "foreign" data using OpenCV (e.g. when you implement + a DirectShow filter or a processing module for gstreamer etc.), e.g. + + \code + void process_video_frame(const unsigned char* pixels, + int width, int height, int step) + { + cv::Mat img(height, width, CV_8UC3, pixels, step); + cv::GaussianBlur(img, img, cv::Size(7,7), 1.5, 1.5); + } + \endcode + +
      2. for quick initialization of small matrices and/or super-fast element access + + \code + double m[3][3] = {{a, b, c}, {d, e, f}, {g, h, i}}; + cv::Mat M = cv::Mat(3, 3, CV_64F, m).inv(); + \endcode +
      + + partial yet very common cases of this "user-allocated data" case are conversions + from CvMat and IplImage to cv::Mat. For this purpose there are special constructors + taking pointers to CvMat or IplImage and the optional + flag indicating whether to copy the data or not. + + Backward conversion from cv::Mat to CvMat or IplImage is provided via cast operators + cv::Mat::operator CvMat() an cv::Mat::operator IplImage(). + The operators do not copy the data. + + + \code + IplImage* img = cvLoadImage("greatwave.jpg", 1); + Mat mtx(img); // convert IplImage* -> cv::Mat + CvMat oldmat = mtx; // convert cv::Mat -> CvMat + CV_Assert(oldmat.cols == img->width && oldmat.rows == img->height && + oldmat.data.ptr == (uchar*)img->imageData && oldmat.step == img->widthStep); + \endcode + +
    • by using MATLAB-style matrix initializers, cv::Mat::zeros(), cv::Mat::ones(), cv::Mat::eye(), e.g.: + + \code + // create a double-precision identity martix and add it to M. + M += Mat::eye(M.rows, M.cols, CV_64F); + \endcode + +
    • by using comma-separated initializer: + + \code + // create 3x3 double-precision identity matrix + Mat M = (Mat_(3,3) << 1, 0, 0, 0, 1, 0, 0, 0, 1); + \endcode + + here we first call constructor of cv::Mat_ class (that we describe further) with the proper matrix, + and then we just put "<<" operator followed by comma-separated values that can be constants, + variables, expressions etc. Also, note the extra parentheses that are needed to avoid compiler errors. + +
    + + Once matrix is created, it will be automatically managed by using reference-counting mechanism + (unless the matrix header is built on top of user-allocated data, + in which case you should handle the data by yourself). + The matrix data will be deallocated when no one points to it; + if you want to release the data pointed by a matrix header before the matrix destructor is called, + use cv::Mat::release(). + + The next important thing to learn about the matrix class is element access. Here is how the matrix is stored. + The elements are stored in row-major order (row by row). The cv::Mat::data member points to the first element of the first row, + cv::Mat::rows contains the number of matrix rows and cv::Mat::cols - the number of matrix columns. There is yet another member, + cv::Mat::step that is used to actually compute address of a matrix element. cv::Mat::step is needed because the matrix can be + a part of another matrix or because there can some padding space in the end of each row for a proper alignment. + + \image html roi.png + + Given these parameters, address of the matrix element M_{ij} is computed as following: + + addr(M_{ij})=M.data + M.step*i + j*M.elemSize() + + if you know the matrix element type, e.g. it is float, then you can use cv::Mat::at() method: + + addr(M_{ij})=&M.at(i,j) + + (where & is used to convert the reference returned by cv::Mat::at() to a pointer). + if you need to process a whole row of matrix, the most efficient way is to get + the pointer to the row first, and then just use plain C operator []: + + \code + // compute sum of positive matrix elements + // (assuming that M is double-precision matrix) + double sum=0; + for(int i = 0; i < M.rows; i++) + { + const double* Mi = M.ptr(i); + for(int j = 0; j < M.cols; j++) + sum += std::max(Mi[j], 0.); + } + \endcode + + Some operations, like the above one, do not actually depend on the matrix shape, + they just process elements of a matrix one by one (or elements from multiple matrices + that are sitting in the same place, e.g. matrix addition). Such operations are called + element-wise and it makes sense to check whether all the input/output matrices are continuous, + i.e. have no gaps in the end of each row, and if yes, process them as a single long row: + + \code + // compute sum of positive matrix elements, optimized variant + double sum=0; + int cols = M.cols, rows = M.rows; + if(M.isContinuous()) + { + cols *= rows; + rows = 1; + } + for(int i = 0; i < rows; i++) + { + const double* Mi = M.ptr(i); + for(int j = 0; j < cols; j++) + sum += std::max(Mi[j], 0.); + } + \endcode + in the case of continuous matrix the outer loop body will be executed just once, + so the overhead will be smaller, which will be especially noticeable in the case of small matrices. + + Finally, there are STL-style iterators that are smart enough to skip gaps between successive rows: + \code + // compute sum of positive matrix elements, iterator-based variant + double sum=0; + MatConstIterator_ it = M.begin(), it_end = M.end(); + for(; it != it_end; ++it) + sum += std::max(*it, 0.); + \endcode + + The matrix iterators are random-access iterators, so they can be passed + to any STL algorithm, including std::sort(). +*/ +class CV_EXPORTS Mat +{ +public: + //! default constructor + Mat(); + //! constructs 2D matrix of the specified size and type + // (_type is CV_8UC1, CV_64FC3, CV_32SC(12) etc.) + Mat(int rows, int cols, int type); + Mat(Size size, int type); + //! constucts 2D matrix and fills it with the specified value _s. + Mat(int rows, int cols, int type, const Scalar& s); + Mat(Size size, int type, const Scalar& s); + + //! constructs n-dimensional matrix + Mat(int ndims, const int* sizes, int type); + Mat(int ndims, const int* sizes, int type, const Scalar& s); + + //! copy constructor + Mat(const Mat& m); + //! constructor for matrix headers pointing to user-allocated data + Mat(int rows, int cols, int type, void* data, size_t step=AUTO_STEP); + Mat(Size size, int type, void* data, size_t step=AUTO_STEP); + Mat(int ndims, const int* sizes, int type, void* data, const size_t* steps=0); + + //! creates a matrix header for a part of the bigger matrix + Mat(const Mat& m, const Range& rowRange, const Range& colRange=Range::all()); + Mat(const Mat& m, const Rect& roi); + Mat(const Mat& m, const Range* ranges); + //! builds matrix from std::vector with or without copying the data + template explicit Mat(const std::vector<_Tp>& vec, bool copyData=false); + //! builds matrix from cv::Vec; the data is copied by default + template explicit Mat(const Vec<_Tp, n>& vec, bool copyData=true); + //! builds matrix from cv::Matx; the data is copied by default + template explicit Mat(const Matx<_Tp, m, n>& mtx, bool copyData=true); + //! builds matrix from a 2D point + template explicit Mat(const Point_<_Tp>& pt, bool copyData=true); + //! builds matrix from a 3D point + template explicit Mat(const Point3_<_Tp>& pt, bool copyData=true); + //! builds matrix from comma initializer + template explicit Mat(const MatCommaInitializer_<_Tp>& commaInitializer); + + // //! converts old-style CvMat to the new matrix; the data is not copied by default + // Mat(const CvMat* m, bool copyData=false); + // //! converts old-style CvMatND to the new matrix; the data is not copied by default + // Mat(const CvMatND* m, bool copyData=false); + // //! converts old-style IplImage to the new matrix; the data is not copied by default + // Mat(const IplImage* img, bool copyData=false); + //Mat(const void* img, bool copyData=false); + + //! download data from GpuMat + explicit Mat(const gpu::GpuMat& m); + + //! destructor - calls release() + ~Mat(); + //! assignment operators + Mat& operator = (const Mat& m); + Mat& operator = (const MatExpr& expr); + + //! returns a new matrix header for the specified row + Mat row(int y) const; + //! returns a new matrix header for the specified column + Mat col(int x) const; + //! ... for the specified row span + Mat rowRange(int startrow, int endrow) const; + Mat rowRange(const Range& r) const; + //! ... for the specified column span + Mat colRange(int startcol, int endcol) const; + Mat colRange(const Range& r) const; + //! ... for the specified diagonal + // (d=0 - the main diagonal, + // >0 - a diagonal from the lower half, + // <0 - a diagonal from the upper half) + Mat diag(int d=0) const; + //! constructs a square diagonal matrix which main diagonal is vector "d" + static Mat diag(const Mat& d); + + //! returns deep copy of the matrix, i.e. the data is copied + Mat clone() const; + //! copies the matrix content to "m". + // It calls m.create(this->size(), this->type()). + void copyTo( OutputArray m ) const; + //! copies those matrix elements to "m" that are marked with non-zero mask elements. + void copyTo( OutputArray m, InputArray mask ) const; + //! converts matrix to another datatype with optional scalng.

Such a sparse array can store elements + of any type that cv::Mat is able to store. "Sparse" means that only non-zero elements + are stored (though, as a result of some operations on a sparse matrix, some of its stored elements + can actually become 0. It's user responsibility to detect such elements and delete them using cv::SparseMat::erase(). + The non-zero elements are stored in a hash table that grows when it's filled enough, + so that the search time remains O(1) in average. Elements can be accessed using the following methods: + +
      +
    1. Query operations: cv::SparseMat::ptr() and the higher-level cv::SparseMat::ref(), + cv::SparseMat::value() and cv::SparseMat::find, for example: + \code + const int dims = 5; + int size[] = {10, 10, 10, 10, 10}; + SparseMat sparse_mat(dims, size, CV_32F); + for(int i = 0; i < 1000; i++) + { + int idx[dims]; + for(int k = 0; k < dims; k++) + idx[k] = rand()%sparse_mat.size(k); + sparse_mat.ref(idx) += 1.f; + } + \endcode + +
    2. Sparse matrix iterators. Like cv::Mat iterators and unlike cv::Mat iterators, the sparse matrix iterators are STL-style, + that is, the iteration is done as following: + \code + // prints elements of a sparse floating-point matrix and the sum of elements. + SparseMatConstIterator_ + it = sparse_mat.begin(), + it_end = sparse_mat.end(); + double s = 0; + int dims = sparse_mat.dims(); + for(; it != it_end; ++it) + { + // print element indices and the element value + const Node* n = it.node(); + printf("(") + for(int i = 0; i < dims; i++) + printf("%3d%c", n->idx[i], i < dims-1 ? ',' : ')'); + printf(": %f\n", *it); + s += *it; + } + printf("Element sum is %g\n", s); + \endcode + If you run this loop, you will notice that elements are enumerated + in no any logical order (lexicographical etc.), + they come in the same order as they stored in the hash table, i.e. semi-randomly. + + You may collect pointers to the nodes and sort them to get the proper ordering. + Note, however, that pointers to the nodes may become invalid when you add more + elements to the matrix; this is because of possible buffer reallocation. + +
    3. A combination of the above 2 methods when you need to process 2 or more sparse + matrices simultaneously, e.g. this is how you can compute unnormalized + cross-correlation of the 2 floating-point sparse matrices: + \code + double crossCorr(const SparseMat& a, const SparseMat& b) + { + const SparseMat *_a = &a, *_b = &b; + // if b contains less elements than a, + // it's faster to iterate through b + if(_a->nzcount() > _b->nzcount()) + std::swap(_a, _b); + SparseMatConstIterator_ it = _a->begin(), + it_end = _a->end(); + double ccorr = 0; + for(; it != it_end; ++it) + { + // take the next element from the first matrix + float avalue = *it; + const Node* anode = it.node(); + // and try to find element with the same index in the second matrix. + // since the hash value depends only on the element index, + // we reuse hashvalue stored in the node + float bvalue = _b->value(anode->idx,&anode->hashval); + ccorr += avalue*bvalue; + } + return ccorr; + } + \endcode +
