//! Smart pointer for GPU memory with reference counting.
|
||||
//! Its interface is mostly similar with cv::Mat.
|
||||
/** @brief Base storage class for GPU memory with reference counting.
|
||||
|
||||
Its interface matches the Mat interface with the following limitations:
|
||||
|
||||
- no arbitrary dimensions support (only 2D)
|
||||
- no functions that return references to their data (because references on GPU are not valid for
|
||||
CPU)
|
||||
- no expression templates technique support
|
||||
|
||||
Beware that the latter limitation may lead to overloaded matrix operators that cause memory
|
||||
allocations. The GpuMat class is convertible to cuda::PtrStepSz and cuda::PtrStep so it can be
|
||||
passed directly to the kernel.
|
||||
|
||||
@note In contrast with Mat, in most cases GpuMat::isContinuous() == false . This means that rows are
|
||||
aligned to a size depending on the hardware. Single-row GpuMat is always a continuous matrix.
|
||||
|
||||
@note You are not recommended to leave static or global GpuMat variables allocated, that is, to rely
|
||||
on its destructor. The destruction order of such variables and CUDA context is undefined. GPU memory
|
||||
release function returns error if the CUDA context has been destroyed before.

CUDA Module Introduction {#cuda_intro}
|
||||
========================
|
||||
|
||||
General Information
|
||||
-------------------
|
||||
|
||||
The OpenCV CUDA module is a set of classes and functions to utilize CUDA computational capabilities.
|
||||
It is implemented using NVIDIA\* CUDA\* Runtime API and supports only NVIDIA GPUs. The OpenCV CUDA
|
||||
module includes utility functions, low-level vision primitives, and high-level algorithms. The
|
||||
utility functions and low-level primitives provide a powerful infrastructure for developing fast
|
||||
vision algorithms taking advantage of CUDA whereas the high-level functionality includes some
|
||||
state-of-the-art algorithms (such as stereo correspondence, face and people detectors, and others)
|
||||
ready to be used by the application developers.
|
||||
|
||||
The CUDA module is designed as a host-level API. This means that if you have pre-compiled OpenCV
|
||||
CUDA binaries, you are not required to have the CUDA Toolkit installed or write any extra code to
|
||||
make use of the CUDA.
|
||||
|
||||
The OpenCV CUDA module is designed for ease of use and does not require any knowledge of CUDA.
|
||||
Though, such a knowledge will certainly be useful to handle non-trivial cases or achieve the highest
|
||||
performance. It is helpful to understand the cost of various operations, what the GPU does, what the
|
||||
preferred data formats are, and so on. The CUDA module is an effective instrument for quick
|
||||
implementation of CUDA-accelerated computer vision algorithms. However, if your algorithm involves
|
||||
many simple operations, then, for the best possible performance, you may still need to write your
|
||||
own kernels to avoid extra write and read operations on the intermediate results.
|
||||
|
||||
To enable CUDA support, configure OpenCV using CMake with WITH\_CUDA=ON . When the flag is set and
|
||||
if CUDA is installed, the full-featured OpenCV CUDA module is built. Otherwise, the module is still
|
||||
built but at runtime all functions from the module throw Exception with CV\_GpuNotSupported error
|
||||
code, except for cuda::getCudaEnabledDeviceCount(). The latter function returns zero GPU count in
|
||||
this case. Building OpenCV without CUDA support does not perform device code compilation, so it does
|
||||
not require the CUDA Toolkit installed. Therefore, using the cuda::getCudaEnabledDeviceCount()
|
||||
function, you can implement a high-level algorithm that will detect GPU presence at runtime and
|
||||
choose an appropriate implementation (CPU or GPU) accordingly.
|
||||
|
||||
Compilation for Different NVIDIA\* Platforms
|
||||
--------------------------------------------
|
||||
|
||||
NVIDIA\* compiler enables generating binary code (cubin and fatbin) and intermediate code (PTX).
|
||||
Binary code often implies a specific GPU architecture and generation, so the compatibility with
|
||||
other GPUs is not guaranteed. PTX is targeted for a virtual platform that is defined entirely by the
|
||||
set of capabilities or features. Depending on the selected virtual platform, some of the
|
||||
instructions are emulated or disabled, even if the real hardware supports all the features.
|
||||
|
||||
At the first call, the PTX code is compiled to binary code for the particular GPU using a JIT
|
||||
compiler. When the target GPU has a compute capability (CC) lower than the PTX code, JIT fails. By
|
||||
default, the OpenCV CUDA module includes:
|
||||
|
||||
\*
|
||||
Binaries for compute capabilities 1.3 and 2.0 (controlled by CUDA\_ARCH\_BIN in CMake)
|
||||
|
||||
\*
|
||||
PTX code for compute capabilities 1.1 and 1.3 (controlled by CUDA\_ARCH\_PTX in CMake)
|
||||
|
||||
This means that for devices with CC 1.3 and 2.0 binary images are ready to run. For all newer
|
||||
platforms, the PTX code for 1.3 is JIT'ed to a binary image. For devices with CC 1.1 and 1.2, the
|
||||
PTX for 1.1 is JIT'ed. For devices with CC 1.0, no code is available and the functions throw
|
||||
Exception. For platforms where JIT compilation is performed first, the run is slow.
|
||||
|
||||
On a GPU with CC 1.0, you can still compile the CUDA module and most of the functions will run
|
||||
flawlessly. To achieve this, add "1.0" to the list of binaries, for example,
|
||||
CUDA\_ARCH\_BIN="1.0 1.3 2.0" . The functions that cannot be run on CC 1.0 GPUs throw an exception.
|
||||
|
||||
You can always determine at runtime whether the OpenCV GPU-built binaries (or PTX code) are
|
||||
compatible with your GPU. The function cuda::DeviceInfo::isCompatible returns the compatibility
|
||||
status (true/false).
|
||||
|
||||
Utilizing Multiple GPUs
|
||||
-----------------------
|
||||
|
||||
In the current version, each of the OpenCV CUDA algorithms can use only a single GPU. So, to utilize
|
||||
multiple GPUs, you have to manually distribute the work between GPUs. Switching active devie can be
|
||||
done using cuda::setDevice() function. For more details please read Cuda C Programming Guide.
|
||||
|
||||
While developing algorithms for multiple GPUs, note a data passing overhead. For primitive functions
|
||||
and small images, it can be significant, which may eliminate all the advantages of having multiple
|
||||
GPUs. But for high-level algorithms, consider using multi-GPU acceleration. For example, the Stereo
|
||||
Block Matching algorithm has been successfully parallelized using the following algorithm:
|
||||
|
||||
1. Split each image of the stereo pair into two horizontal overlapping stripes.
|
||||
2. Process each pair of stripes (from the left and right images) on a separate Fermi\* GPU.
|
||||
3. Merge the results into a single disparity map.
|
||||
|
||||
With this algorithm, a dual GPU gave a 180% performance increase comparing to the single Fermi GPU.
|
||||

/** @brief Class computing stereo correspondence using the belief propagation algorithm. :
|
||||
|

The class implements algorithm described in @cite Felzenszwalb2006 . It can compute own data cost
|
||||
(using a truncated linear model) or use a user-provided data cost.
|
||||
|
||||
@note
|
||||
StereoBeliefPropagation requires a lot of memory for message storage:
|
||||
|
||||
\f[width \_ step \cdot height \cdot ndisp \cdot 4 \cdot (1 + 0.25)\f]
|
||||
|
||||
and for data cost storage:
|
||||
|
||||
\f[width\_step \cdot height \cdot ndisp \cdot (1 + 0.25 + 0.0625 + \dotsm + \frac{1}{4^{levels}})\f]
|
||||
|
||||
width\_step is the number of bytes in a line including padding.
|
||||
|
||||
StereoBeliefPropagation uses a truncated linear model for the data cost and discontinuity terms:
|
||||
|
||||
\f[DataCost = data \_ weight \cdot \min ( \lvert Img_Left(x,y)-Img_Right(x-d,y) \rvert , max \_ data \_ term)\f]
|
||||
|
||||
\f[DiscTerm = \min (disc \_ single \_ jump \cdot \lvert f_1-f_2 \rvert , max \_ disc \_ term)\f]
|
||||
|
||||
For more details, see @cite Felzenszwalb2006.
|
||||
|
||||
By default, StereoBeliefPropagation uses floating-point arithmetics and the CV\_32FC1 type for
|
||||
messages. But it can also use fixed-point arithmetics and the CV\_16SC1 message type for better
|
||||
performance. To avoid an overflow in this case, the parameters must satisfy the following
