From 81d6842b8eb927ab105620a9a0716a7debe6b8c9 Mon Sep 17 00:00:00 2001 From: Tony Date: Wed, 2 Oct 2013 21:16:40 +0100 Subject: [PATCH 001/454] These changes introduce Gtk3 support into the highgui module. A new option WITH_GTK3 has been added to the cmake configure system to enable compilation under Gtk version 3.The flag HAVE_GTK3 is also introduced to select the new Gtk3 code in the source files. (Gtk2 is disbled when Gtk3 is selected). window_gtk.cpp has been modified to remove obsolete (and deleted from libgtk 3) and introduce new Gtk3 code in its place when compiled for Gtk3. To compile for Gtk2, disable WITH_GTK3 in cmake. To build for Gtk3 both WITH_GTK and WITH_GTK3 must be selected. --- CMakeLists.txt | 2 + cmake/OpenCVFindLibsGUI.cmake | 8 +- cmake/templates/cvconfig.h.cmake | 3 + modules/highgui/CMakeLists.txt | 2 +- modules/highgui/src/window.cpp | 11 ++ modules/highgui/src/window_gtk.cpp | 207 ++++++++++++++++++++++++++--- 6 files changed, 211 insertions(+), 22 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 00c35a949..c989e81a0 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -120,6 +120,7 @@ OCV_OPTION(WITH_FFMPEG "Include FFMPEG support" ON OCV_OPTION(WITH_GSTREAMER "Include Gstreamer support" ON IF (UNIX AND NOT APPLE AND NOT ANDROID) ) OCV_OPTION(WITH_GSTREAMER_1_X "Include Gstreamer 1.x support" OFF) OCV_OPTION(WITH_GTK "Include GTK support" ON IF (UNIX AND NOT APPLE AND NOT ANDROID) ) +OCV_OPTION(WITH_GTK3 "Include GTK3 support" ON IF (UNIX AND WITH_GTK AND NOT APPLE AND NOT ANDROID) ) OCV_OPTION(WITH_IPP "Include Intel IPP support" OFF IF (MSVC OR X86 OR X86_64) ) OCV_OPTION(WITH_JASPER "Include JPEG2K support" ON IF (NOT IOS) ) OCV_OPTION(WITH_JPEG "Include JPEG support" ON) @@ -603,6 +604,7 @@ else() endif() else() status(" GTK+ 2.x:" HAVE_GTK THEN "YES (ver ${ALIASOF_gtk+-2.0_VERSION})" ELSE NO) + status(" GTK+ 3.x:" HAVE_GTK3 THEN "YES (ver ${ALIASOF_gtk+-3.0_VERSION})" ELSE NO) status(" GThread :" HAVE_GTHREAD THEN "YES (ver ${ALIASOF_gthread-2.0_VERSION})" ELSE NO) status(" GtkGlExt:" HAVE_GTKGLEXT THEN "YES (ver ${ALIASOF_gtkglext-1.0_VERSION})" ELSE NO) endif() diff --git a/cmake/OpenCVFindLibsGUI.cmake b/cmake/OpenCVFindLibsGUI.cmake index c80beca05..d09ed892b 100644 --- a/cmake/OpenCVFindLibsGUI.cmake +++ b/cmake/OpenCVFindLibsGUI.cmake @@ -39,9 +39,13 @@ if(WITH_QT) endif() # --- GTK --- -ocv_clear_vars(HAVE_GTK HAVE_GTHREAD HAVE_GTKGLEXT) +ocv_clear_vars(HAVE_GTK HAVE_GTK3 HAVE_GTHREAD HAVE_GTKGLEXT) if(WITH_GTK AND NOT HAVE_QT) - CHECK_MODULE(gtk+-2.0 HAVE_GTK) + if(WITH_GTK3) + CHECK_MODULE(gtk+-3.0 HAVE_GTK3) + else() + CHECK_MODULE(gtk+-2.0 HAVE_GTK) + endif() CHECK_MODULE(gthread-2.0 HAVE_GTHREAD) if(WITH_OPENGL) CHECK_MODULE(gtkglext-1.0 HAVE_GTKGLEXT) diff --git a/cmake/templates/cvconfig.h.cmake b/cmake/templates/cvconfig.h.cmake index 56c5d5aad..68e2d13c9 100644 --- a/cmake/templates/cvconfig.h.cmake +++ b/cmake/templates/cvconfig.h.cmake @@ -82,6 +82,9 @@ /* GTK+ 2.x toolkit */ #cmakedefine HAVE_GTK +/* GTK+ 3.x toolkit */ +#cmakedefine HAVE_GTK3 + /* Define to 1 if you have the header file. */ #cmakedefine HAVE_INTTYPES_H 1 diff --git a/modules/highgui/CMakeLists.txt b/modules/highgui/CMakeLists.txt index 011bb0dc3..e8505f416 100644 --- a/modules/highgui/CMakeLists.txt +++ b/modules/highgui/CMakeLists.txt @@ -106,7 +106,7 @@ elseif(HAVE_QT) endif() elseif(HAVE_WIN32UI) list(APPEND highgui_srcs src/window_w32.cpp) -elseif(HAVE_GTK) +elseif(HAVE_GTK OR HAVE_GTK3) list(APPEND highgui_srcs src/window_gtk.cpp) elseif(HAVE_CARBON) list(APPEND highgui_srcs src/window_carbon.cpp) diff --git a/modules/highgui/src/window.cpp b/modules/highgui/src/window.cpp index 428ef51ef..6d5047075 100644 --- a/modules/highgui/src/window.cpp +++ b/modules/highgui/src/window.cpp @@ -61,6 +61,8 @@ CV_IMPL void cvSetWindowProperty(const char* name, int prop_id, double prop_valu cvSetModeWindow_W32(name,prop_value);

The new logic will select GTK+3 by default if WITH_GTK is selected. If the GTK+3 libraries are not found, then GTK+2 libraries will be selected if found.

The change requires discussion for making it completely functional as redundancy is required given that if the source is a video file, the old code pathways must be used. Otherwise all IMFMediaSession, IMFMediaSource, and IMFActivate code must use a MediaCapture code path and all sink code must use the CMediaSink custom sink. Support for the custom sink is extended to non-WinRT not for compatibility as Windows Vista client is a minimum regardless, but because it offers more flexibility, could be faster and is able to be used as an optionally different code path during sink creation based on a future configuration parameter. My discussion and proposal to finish this change: Devices are so easily enumerated through WinRT Windows.Devices namespace that wrapping the calls in a library is quite a chore for little benefit though to get the various modes and formats could still be a worthwhile project. For now conditional compilation to remove videodevices and any offending non-video file related activity in videodevice. In my opinion, this is a different , far less fundamental and important change which can possibly be done as a future project and also much more easily implemented in C++/CX. ImageGrabber has the IMFSampleGrabberSinkCallback replaced with a base class (SharedSampleGrabber) which also be is base class for ImageGrabberRT. This change is necessary as the custom sink does not require a thread to pump events which is done through MediaCapture already. IMFSampleGrabberSinkCallback is the common element between both models and that piece can be shared. Initializing the new ImageGrabberRT is as simple as passing an already initialized MediaCapture object and any video format/encoding parameters. The concurrency event is necessary to wait for completion and is the way the underlying, IAsyncAction wrappers in the task library work as well. Native WIN32 event objects would be an option if HAVE_CONCURRENCY is not defined. I could even imagine doing it with sleep/thread yield and InterlockedCompareExchange yet I am not enthusiastic about that approach either. Since there is a specific compiler HAVE_ for concurrency, I do not like pulling it in though I think for WinRT it is safe to say we will always have it available though should probably conditionally compile with the Interlocked option as WIN32 events would require HAVE_WIN32. It looks like C++/CX cannot be used for the IMediaExtension sink (which should not be a problem) as using COM objects requires WRL and though deriving from IMediaExtension can be done, there is little purpose without COM. Objects from C++/CX can be swapped to interact with objects from native C++ as Inspectable* can reinterpret_cast to the ref object IInspectable^ and vice-versa. A solution to the COM class with C++/CX would be great so we could have dual support. Also without #define for every WRL object in use, the code will get quite muddy given that the */^ would need to be ifdef'd everywhere. Update cap_msmf.cpp Fixed bugs and completed the change. I believe the new classes need to be moved to a header file as the file has become to large and more classes need to be added for handling all the asynchronous problems (one wrapping IAsyncAction in a task and another for making a task out of IAsyncAction). Unfortunately, blocking on the UI thread is not an option in WinRT so a synchronous architecture is considered "illegal" by Microsoft's standards even if implementable (C++/CX ppltasks library throws errors if you try it). Worse, either by design or a bug in the MF MediaCapture class with Custom Sinks causes a crash if stop/start previewing without reinitializing (spPreferredPreviewMediaType is fatally nulled). After decompiling Windows.Media.dll, I worked around this in my own projects by using an activate-able custom sink ID which strangely assigns 1 to this pointer allowing it to be reinitialized in what can only be described as a hack by Microsoft. This would add additional overhead to the project to implement especially for static libraries as it requires IDL/DLL exporting followed by manifest declaration. Better to document that it is not supported. Furthermore, an additional class for IMFAttributes should be implemented to make clean architecture for passing around attributes as opposed to directly calling non-COM interface calls on the objects and making use of SetProperties which would also be a set up for an object that uses the RuntimeClass activation ID. The remaining changes are not difficult and will be complete soon along with debug tracing messages.

That is, the two features in both sets should match each other. It provides consistant result, and is a good alternative to ratio test proposed by D.Lowe in SIFT paper.

But: Every :ocv:class:`FaceRecognizer` is an :ocv:class:`Algorithm`, so you can easily get/set all model internals (if allowed by the implementation). :ocv:class:`Algorithm` is a relatively new OpenCV concept, which is available since the 2.4 release. I suggest you take a look at its description. - -:ocv:class:`Algorithm` provides the following features for all derived classes: - -* So called “virtual constructorâ€. That is, each Algorithm derivative is registered at program start and you can get the list of registered algorithms and create instance of a particular algorithm by its name (see :ocv:func:`Algorithm::create`). If you plan to add your own algorithms, it is good practice to add a unique prefix to your algorithms to distinguish them from other algorithms. - -* Setting/Retrieving algorithm parameters by name. If you used video capturing functionality from OpenCV highgui module, you are probably familar with :ocv:cfunc:`cvSetCaptureProperty`, :ocv:cfunc:`cvGetCaptureProperty`, :ocv:func:`VideoCapture::set` and :ocv:func:`VideoCapture::get`. :ocv:class:`Algorithm` provides similar method where instead of integer id's you specify the parameter names as text Strings. See :ocv:func:`Algorithm::set` and :ocv:func:`Algorithm::get` for details. - -* Reading and writing parameters from/to XML or YAML files. Every Algorithm derivative can store all its parameters and then read them back. There is no need to re-implement it each time. - -Moreover every :ocv:class:`FaceRecognizer` supports the: - -* **Training** of a :ocv:class:`FaceRecognizer` with :ocv:func:`FaceRecognizer::train` on a given set of images (your face database!). - -* **Prediction** of a given sample image, that means a face. The image is given as a :ocv:class:`Mat`. - -* **Loading/Saving** the model state from/to a given XML or YAML. - -.. note:: When using the FaceRecognizer interface in combination with Python, please stick to Python 2. Some underlying scripts like create_csv will not work in other versions, like Python 3. - -Setting the Thresholds -+++++++++++++++++++++++ - -Sometimes you run into the situation, when you want to apply a threshold on the prediction. A common scenario in face recognition is to tell, whether a face belongs to the training dataset or if it is unknown. You might wonder, why there's no public API in :ocv:class:`FaceRecognizer` to set the threshold for the prediction, but rest assured: It's supported. It just means there's no generic way in an abstract class to provide an interface for setting/getting the thresholds of *every possible* :ocv:class:`FaceRecognizer` algorithm. The appropriate place to set the thresholds is in the constructor of the specific :ocv:class:`FaceRecognizer` and since every :ocv:class:`FaceRecognizer` is a :ocv:class:`Algorithm` (see above), you can get/set the thresholds at runtime! - -Here is an example of setting a threshold for the Eigenfaces method, when creating the model: - -.. code-block:: cpp - - // Let's say we want to keep 10 Eigenfaces and have a threshold value of 10.0 - int num_components = 10; - double threshold = 10.0; - // Then if you want to have a cv::FaceRecognizer with a confidence threshold, - // create the concrete implementation with the appropiate parameters: - Ptr model = createEigenFaceRecognizer(num_components, threshold); - -Sometimes it's impossible to train the model, just to experiment with threshold values. Thanks to :ocv:class:`Algorithm` it's possible to set internal model thresholds during runtime. Let's see how we would set/get the prediction for the Eigenface model, we've created above: - -.. code-block:: cpp - - // The following line reads the threshold from the Eigenfaces model: - double current_threshold = model->getDouble("threshold"); - // And this line sets the threshold to 0.0: - model->set("threshold", 0.0); - -If you've set the threshold to ``0.0`` as we did above, then: - -.. code-block:: cpp - - // - Mat img = imread("person1/3.jpg", CV_LOAD_IMAGE_GRAYSCALE); - // Get a prediction from the model. Note: We've set a threshold of 0.0 above, - // since the distance is almost always larger than 0.0, you'll get -1 as - // label, which indicates, this face is unknown - int predicted_label = model->predict(img); - // ... - -is going to yield ``-1`` as predicted label, which states this face is unknown. - -Getting the name of a FaceRecognizer -+++++++++++++++++++++++++++++++++++++ - -Since every :ocv:class:`FaceRecognizer` is a :ocv:class:`Algorithm`, you can use :ocv:func:`Algorithm::name` to get the name of a :ocv:class:`FaceRecognizer`: - -.. code-block:: cpp - - // Create a FaceRecognizer: - Ptr model = createEigenFaceRecognizer(); - // And here's how to get its name: - String name = model->name(); - - -FaceRecognizer::train ---------------------- - -Trains a FaceRecognizer with given data and associated labels. - -.. ocv:function:: void FaceRecognizer::train( InputArrayOfArrays src, InputArray labels ) = 0 - - :param src: The training images, that means the faces you want to learn. The data has to be given as a ``vector``. - - :param labels: The labels corresponding to the images have to be given either as a ``vector`` or a - -The following source code snippet shows you how to learn a Fisherfaces model on a given set of images. The images are read with :ocv:func:`imread` and pushed into a ``std::vector``. The labels of each image are stored within a ``std::vector`` (you could also use a :ocv:class:`Mat` of type `CV_32SC1`). Think of the label as the subject (the person) this image belongs to, so same subjects (persons) should have the same label. For the available :ocv:class:`FaceRecognizer` you don't have to pay any attention to the order of the labels, just make sure same persons have the same label: - -.. code-block:: cpp - - // holds images and labels - vector images; - vector labels; - // images for first person - images.push_back(imread("person0/0.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(0); - images.push_back(imread("person0/1.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(0); - images.push_back(imread("person0/2.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(0); - // images for second person - images.push_back(imread("person1/0.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(1); - images.push_back(imread("person1/1.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(1); - images.push_back(imread("person1/2.jpg", CV_LOAD_IMAGE_GRAYSCALE)); labels.push_back(1); - -Now that you have read some images, we can create a new :ocv:class:`FaceRecognizer`. In this example I'll create a Fisherfaces model and decide to keep all of the possible Fisherfaces: - -.. code-block:: cpp - - // Create a new Fisherfaces model and retain all available Fisherfaces, - // this is the most common usage of this specific FaceRecognizer: - // - Ptr model = createFisherFaceRecognizer(); - -And finally train it on the given dataset (the face images and labels): - -.. code-block:: cpp - - // This is the common interface to train all of the available cv::FaceRecognizer - // implementations: - // - model->train(images, labels); - -FaceRecognizer::update ----------------------- - -Updates a FaceRecognizer with given data and associated labels. - -.. ocv:function:: void FaceRecognizer::update( InputArrayOfArrays src, InputArray labels ) - - :param src: The training images, that means the faces you want to learn.

The Local Binary Patterns Histograms (LBPH) recognizer (see :ocv:func:`createLBPHFaceRecognizer`) can be updated. For the Eigenfaces and Fisherfaces method, this is algorithmically not possible and you have to re-estimate the model with :ocv:func:`FaceRecognizer::train`.

Although it might be interesting for very advanced users, I've decided to leave the implementation details out as I am afraid they confuse new users. - -All code in this document is released under the `BSD license `_, so feel free to use it for your projects. - -Face Recognition -================ - -Face recognition is an easy task for humans. Experiments in [Tu06]_ have shown, that even one to three day old babies are able to distinguish between known faces. So how hard could it be for a computer? It turns out we know little about human recognition to date. Are inner features (eyes, nose, mouth) or outer features (head shape, hairline) used for a successful face recognition? How do we analyze an image and how does the brain encode it? It was shown by `David Hubel `_ and `Torsten Wiesel `_, that our brain has specialized nerve cells responding to specific local features of a scene, such as lines, edges, angles or movement. Since we don't see the world as scattered pieces, our visual cortex must somehow combine the different sources of information into useful patterns. Automatic face recognition is all about extracting those meaningful features from an image, putting them into a useful representation and performing some kind of classification on them. - -Face recognition based on the geometric features of a face is probably the most intuitive approach to face recognition. One of the first automated face recognition systems was described in [Kanade73]_: marker points (position of eyes, ears, nose, ...) were used to build a feature vector (distance between the points, angle between them, ...). The recognition was performed by calculating the euclidean distance between feature vectors of a probe and reference image. Such a method is robust against changes in illumination by its nature, but has a huge drawback: the accurate registration of the marker points is complicated, even with state of the art algorithms. Some of the latest work on geometric face recognition was carried out in [Bru92]_. A 22-dimensional feature vector was used and experiments on large datasets have shown, that geometrical features alone my not carry enough information for face recognition. - -The Eigenfaces method described in [TP91]_ took a holistic approach to face recognition: A facial image is a point from a high-dimensional image space and a lower-dimensional representation is found, where classification becomes easy. The lower-dimensional subspace is found with Principal Component Analysis, which identifies the axes with maximum variance. While this kind of transformation is optimal from a reconstruction standpoint, it doesn't take any class labels into account. Imagine a situation where the variance is generated from external sources, let it be light. The axes with maximum variance do not necessarily contain any discriminative information at all, hence a classification becomes impossible. So a class-specific projection with a Linear Discriminant Analysis was applied to face recognition in [BHK97]_. The basic idea is to minimize the variance within a class, while maximizing the variance between the classes at the same time. - -Recently various methods for a local feature extraction emerged. To avoid the high-dimensionality of the input data only local regions of an image are described, the extracted features are (hopefully) more robust against partial occlusion, illumation and small sample size. Algorithms used for a local feature extraction are Gabor Wavelets ([Wiskott97]_), Discrete Cosinus Transform ([Messer06]_) and Local Binary Patterns ([AHP04]_). It's still an open research question what's the best way to preserve spatial information when applying a local feature extraction, because spatial information is potentially useful information. - -Face Database -============== - -Let's get some data to experiment with first. I don't want to do a toy example here. We are doing face recognition, so you'll need some face images! You can either create your own dataset or start with one of the available face databases, `http://face-rec.org/databases/ `_ gives you an up-to-date overview. Three interesting databases are (parts of the description are quoted from `http://face-rec.org `_): - -* `AT&T Facedatabase `_ The AT&T Facedatabase, sometimes also referred to as *ORL Database of Faces*, contains ten different images of each of 40 distinct subjects. For some subjects, the images were taken at different times, varying the lighting, facial expressions (open / closed eyes, smiling / not smiling) and facial details (glasses / no glasses). All the images were taken against a dark homogeneous background with the subjects in an upright, frontal position (with tolerance for some side movement). - -* `Yale Facedatabase A `_, also known as Yalefaces. The AT&T Facedatabase is good for initial tests, but it's a fairly easy database. The Eigenfaces method already has a 97% recognition rate on it, so you won't see any great improvements with other algorithms. The Yale Facedatabase A (also known as Yalefaces) is a more appropriate dataset for initial experiments, because the recognition problem is harder. The database consists of 15 people (14 male, 1 female) each with 11 grayscale images sized :math:`320 \times 243` pixel. There are changes in the light conditions (center light, left light, right light), facial expressions (happy, normal, sad, sleepy, surprised, wink) and glasses (glasses, no-glasses). - - The original images are not cropped and aligned. Please look into the :ref:`appendixft` for a Python script, that does the job for you. - -* `Extended Yale Facedatabase B `_ The Extended Yale Facedatabase B contains 2414 images of 38 different people in its cropped version. The focus of this database is set on extracting features that are robust to illumination, the images have almost no variation in emotion/occlusion/... . I personally think, that this dataset is too large for the experiments I perform in this document. You better use the `AT&T Facedatabase `_ for intial testing. A first version of the Yale Facedatabase B was used in [BHK97]_ to see how the Eigenfaces and Fisherfaces method perform under heavy illumination changes. [Lee05]_ used the same setup to take 16128 images of 28 people. The Extended Yale Facedatabase B is the merge of the two databases, which is now known as Extended Yalefacedatabase B. - -Preparing the data -------------------- - -Once we have acquired some data, we'll need to read it in our program. In the demo applications I have decided to read the images from a very simple CSV file. Why? Because it's the simplest platform-independent approach I can think of. However, if you know a simpler solution please ping me about it. Basically all the CSV file needs to contain are lines composed of a ``filename`` followed by a ``;`` followed by the ``label`` (as *integer number*), making up a line like this: - -.. code-block:: none - - /path/to/image.ext;0 - -Let's dissect the line. ``/path/to/image.ext`` is the path to an image, probably something like this if you are in Windows: ``C:/faces/person0/image0.jpg``. Then there is the separator ``;`` and finally we assign the label ``0`` to the image. Think of the label as the subject (the person) this image belongs to, so same subjects (persons) should have the same label. - -Download the AT&T Facedatabase from AT&T Facedatabase and the corresponding CSV file from at.txt, which looks like this (file is without ... of course): - -.. code-block:: none - - ./at/s1/1.pgm;0 - ./at/s1/2.pgm;0 - ... - ./at/s2/1.pgm;1 - ./at/s2/2.pgm;1 - ... - ./at/s40/1.pgm;39 - ./at/s40/2.pgm;39 - -Imagine I have extracted the files to ``D:/data/at`` and have downloaded the CSV file to ``D:/data/at.txt``. Then you would simply need to Search & Replace ``./`` with ``D:/data/``. You can do that in an editor of your choice, every sufficiently advanced editor can do this. Once you have a CSV file with valid filenames and labels, you can run any of the demos by passing the path to the CSV file as parameter: - -.. code-block:: none - - facerec_demo.exe D:/data/at.txt - -Creating the CSV File -+++++++++++++++++++++ - -You don't really want to create the CSV file by hand. I have prepared you a little Python script ``create_csv.py`` (you find it at ``src/create_csv.py`` coming with this tutorial) that automatically creates you a CSV file.

Two-dimensional :math:`p \times q` grayscale images span a :math:`m = pq`-dimensional vector space, so an image with :math:`100 \times 100` pixels lies in a :math:`10,000`-dimensional image space already. The question is: Are all dimensions equally useful for us? We can only make a decision if there's any variance in data, so what we are looking for are the components that account for most of the information. The Principal Component Analysis (PCA) was independently proposed by `Karl Pearson `_ (1901) and `Harold Hotelling `_ (1933) to turn a set of possibly correlated variables into a smaller set of uncorrelated variables. The idea is, that a high-dimensional dataset is often described by correlated variables and therefore only a few meaningful dimensions account for most of the information. The PCA method finds the directions with the greatest variance in the data, called principal components. - -Algorithmic Description ------------------------ - -Let :math:`X = \{ x_{1}, x_{2}, \ldots, x_{n} \}` be a random vector with observations :math:`x_i \in R^{d}`. - -1. Compute the mean :math:`\mu` - - .. math:: - - \mu = \frac{1}{n} \sum_{i=1}^{n} x_{i} - -2. Compute the the Covariance Matrix `S` - - .. math:: - - S = \frac{1}{n} \sum_{i=1}^{n} (x_{i} - \mu) (x_{i} - \mu)^{T}` - -3. Compute the eigenvalues :math:`\lambda_{i}` and eigenvectors :math:`v_{i}` of :math:`S` - - .. math:: - - S v_{i} = \lambda_{i} v_{i}, i=1,2,\ldots,n - -4. Order the eigenvectors descending by their eigenvalue. The :math:`k` principal components are the eigenvectors corresponding to the :math:`k` largest eigenvalues. - -The :math:`k` principal components of the observed vector :math:`x` are then given by: - -.. math:: - - y = W^{T} (x - \mu) - - -where :math:`W = (v_{1}, v_{2}, \ldots, v_{k})`. - -The reconstruction from the PCA basis is given by: - -.. math:: - - x = W y + \mu - -where :math:`W = (v_{1}, v_{2}, \ldots, v_{k})`. - - -The Eigenfaces method then performs face recognition by: - -* Projecting all training samples into the PCA subspace. -* Projecting the query image into the PCA subspace. -* Finding the nearest neighbor between the projected training images and the projected query image. - -Still there's one problem left to solve. Imagine we are given :math:`400` images sized :math:`100 \times 100` pixel. The Principal Component Analysis solves the covariance matrix :math:`S = X X^{T}`, where :math:`{size}(X) = 10000 \times 400` in our example. You would end up with a :math:`10000 \times 10000` matrix, roughly :math:`0.8 GB`. Solving this problem isn't feasible, so we'll need to apply a trick. From your linear algebra lessons you know that a :math:`M \times N` matrix with :math:`M > N` can only have :math:`N - 1` non-zero eigenvalues. So it's possible to take the eigenvalue decomposition :math:`S = X^{T} X` of size :math:`N \times N` instead: - -.. math:: - - X^{T} X v_{i} = \lambda_{i} v{i} - - -and get the original eigenvectors of :math:`S = X X^{T}` with a left multiplication of the data matrix: - -.. math:: - - X X^{T} (X v_{i}) = \lambda_{i} (X v_{i}) - -The resulting eigenvectors are orthogonal, to get orthonormal eigenvectors they need to be normalized to unit length. I don't want to turn this into a publication, so please look into [Duda01]_ for the derivation and proof of the equations. - -Eigenfaces in OpenCV --------------------- - -For the first source code example, I'll go through it with you. I am first giving you the whole source code listing, and after this we'll look at the most important lines in detail. Please note: every source code listing is commented in detail, so you should have no problems following it. - -.. literalinclude:: src/facerec_eigenfaces.cpp - :language: cpp - :linenos: - -The source code for this demo application is also available in the ``src`` folder coming with this documentation: - -* :download:`src/facerec_eigenfaces.cpp ` - - -I've used the jet colormap, so you can see how the grayscale values are distributed within the specific Eigenfaces. You can see, that the Eigenfaces do not only encode facial features, but also the illumination in the images (see the left light in Eigenface \#4, right light in Eigenfaces \#5): - -.. image:: img/eigenfaces_opencv.png - :align: center - -We've already seen, that we can reconstruct a face from its lower dimensional approximation. So let's see how many Eigenfaces are needed for a good reconstruction. I'll do a subplot with :math:`10,30,\ldots,310` Eigenfaces: - -.. code-block:: cpp - - // Display or save the image reconstruction at some predefined steps: - for(int num_components = 10; num_components < 300; num_components+=15) { - // slice the eigenvectors from the model - Mat evs = Mat(W, Range::all(), Range(0, num_components)); - Mat projection = subspaceProject(evs, mean, images[0].reshape(1,1)); - Mat reconstruction = subspaceReconstruct(evs, mean, projection); - // Normalize the result: - reconstruction = norm_0_255(reconstruction.reshape(1, images[0].rows)); - // Display or save: - if(argc == 2) { - imshow(format("eigenface_reconstruction_%d", num_components), reconstruction); - } else { - imwrite(format("%s/eigenface_reconstruction_%d.png", output_folder.c_str(), num_components), reconstruction); - } - } - -10 Eigenvectors are obviously not sufficient for a good image reconstruction, 50 Eigenvectors may already be sufficient to encode important facial features. You'll get a good reconstruction with approximately 300 Eigenvectors for the AT&T Facedatabase. There are rule of thumbs how many Eigenfaces you should choose for a successful face recognition, but it heavily depends on the input data. [Zhao03]_ is the perfect point to start researching for this: - -.. image:: img/eigenface_reconstruction_opencv.png - :align: center - - -Fisherfaces -============ - -The Principal Component Analysis (PCA), which is the core of the Eigenfaces method, finds a linear combination of features that maximizes the total variance in data. While this is clearly a powerful way to represent data, it doesn't consider any classes and so a lot of discriminative information *may* be lost when throwing components away. Imagine a situation where the variance in your data is generated by an external source, let it be the light. The components identified by a PCA do not necessarily contain any discriminative information at all, so the projected samples are smeared together and a classification becomes impossible (see `http://www.bytefish.de/wiki/pca_lda_with_gnu_octave `_ for an example). - -The Linear Discriminant Analysis performs a class-specific dimensionality reduction and was invented by the great statistician `Sir R. A. Fisher `_. He successfully used it for classifying flowers in his 1936 paper *The use of multiple measurements in taxonomic problems* [Fisher36]_. In order to find the combination of features that separates best between classes the Linear Discriminant Analysis maximizes the ratio of between-classes to within-classes scatter, instead of maximizing the overall scatter. The idea is simple: same classes should cluster tightly together, while different classes are as far away as possible from each other in the lower-dimensional representation. This was also recognized by `Belhumeur `_, `Hespanha `_ and `Kriegman `_ and so they applied a Discriminant Analysis to face recognition in [BHK97]_. - -Algorithmic Description ------------------------ - -Let :math:`X` be a random vector with samples drawn from :math:`c` classes: - - -.. math:: - :nowrap: - - \begin{align*} - X & = & \{X_1,X_2,\ldots,X_c\} \\ - X_i & = & \{x_1, x_2, \ldots, x_n\} - \end{align*} - - -The scatter matrices :math:`S_{B}` and `S_{W}` are calculated as: - -.. math:: - :nowrap: - - \begin{align*} - S_{B} & = & \sum_{i=1}^{c} N_{i} (\mu_i - \mu)(\mu_i - \mu)^{T} \\ - S_{W} & = & \sum_{i=1}^{c} \sum_{x_{j} \in X_{i}} (x_j - \mu_i)(x_j - \mu_i)^{T} - \end{align*} - -, where :math:`\mu` is the total mean: - -.. math:: - - \mu = \frac{1}{N} \sum_{i=1}^{N} x_i - -And :math:`\mu_i` is the mean of class :math:`i \in \{1,\ldots,c\}`: - -.. math:: - - \mu_i = \frac{1}{|X_i|} \sum_{x_j \in X_i} x_j - -Fisher's classic algorithm now looks for a projection :math:`W`, that maximizes the class separability criterion: - -.. math:: - - W_{opt} = \operatorname{arg\,max}_{W} \frac{|W^T S_B W|}{|W^T S_W W|} - - -Following [BHK97]_, a solution for this optimization problem is given by solving the General Eigenvalue Problem: - -.. math:: - :nowrap: - - \begin{align*} - S_{B} v_{i} & = & \lambda_{i} S_w v_{i} \nonumber \\ - S_{W}^{-1} S_{B} v_{i} & = & \lambda_{i} v_{i} - \end{align*} - -There's one problem left to solve: The rank of :math:`S_{W}` is at most :math:`(N-c)`, with :math:`N` samples and :math:`c` classes. In pattern recognition problems the number of samples :math:`N` is almost always samller than the dimension of the input data (the number of pixels), so the scatter matrix :math:`S_{W}` becomes singular (see [RJ91]_). In [BHK97]_ this was solved by performing a Principal Component Analysis on the data and projecting the samples into the :math:`(N-c)`-dimensional space. A Linear Discriminant Analysis was then performed on the reduced data, because :math:`S_{W}` isn't singular anymore. - -The optimization problem can then be rewritten as: - -.. math:: - :nowrap: - - \begin{align*} - W_{pca} & = & \operatorname{arg\,max}_{W} |W^T S_T W| \\ - W_{fld} & = & \operatorname{arg\,max}_{W} \frac{|W^T W_{pca}^T S_{B} W_{pca} W|}{|W^T W_{pca}^T S_{W} W_{pca} W|} - \end{align*} - -The transformation matrix :math:`W`, that projects a sample into the :math:`(c-1)`-dimensional space is then given by: - -.. math:: - - W = W_{fld}^{T} W_{pca}^{T} - -Fisherfaces in OpenCV ---------------------- - -.. literalinclude:: src/facerec_fisherfaces.cpp - :language: cpp - :linenos: - -The source code for this demo application is also available in the ``src`` folder coming with this documentation: - -* :download:`src/facerec_fisherfaces.cpp ` - - -For this example I am going to use the Yale Facedatabase A, just because the plots are nicer. Each Fisherface has the same length as an original image, thus it can be displayed as an image. The demo shows (or saves) the first, at most 16 Fisherfaces: - -.. image:: img/fisherfaces_opencv.png - :align: center - -The Fisherfaces method learns a class-specific transformation matrix, so the they do not capture illumination as obviously as the Eigenfaces method. The Discriminant Analysis instead finds the facial features to discriminate between the persons. It's important to mention, that the performance of the Fisherfaces heavily depends on the input data as well. Practically said: if you learn the Fisherfaces for well-illuminated pictures only and you try to recognize faces in bad-illuminated scenes, then method is likely to find the wrong components (just because those features may not be predominant on bad illuminated images). This is somewhat logical, since the method had no chance to learn the illumination. - -The Fisherfaces allow a reconstruction of the projected image, just like the Eigenfaces did. But since we only identified the features to distinguish between subjects, you can't expect a nice reconstruction of the original image. For the Fisherfaces method we'll project the sample image onto each of the Fisherfaces instead. So you'll have a nice visualization, which feature each of the Fisherfaces describes: - -.. code-block:: cpp - - // Display or save the image reconstruction at some predefined steps: - for(int num_component = 0; num_component < min(16, W.cols); num_component++) { - // Slice the Fisherface from the model: - Mat ev = W.col(num_component); - Mat projection = subspaceProject(ev, mean, images[0].reshape(1,1)); - Mat reconstruction = subspaceReconstruct(ev, mean, projection); - // Normalize the result: - reconstruction = norm_0_255(reconstruction.reshape(1, images[0].rows)); - // Display or save: - if(argc == 2) { - imshow(format("fisherface_reconstruction_%d", num_component), reconstruction); - } else { - imwrite(format("%s/fisherface_reconstruction_%d.png", output_folder.c_str(), num_component), reconstruction); - } - } - -The differences may be subtle for the human eyes, but you should be able to see some differences: - -.. image:: img/fisherface_reconstruction_opencv.png - :align: center - - -Local Binary Patterns Histograms -================================ - -Eigenfaces and Fisherfaces take a somewhat holistic approach to face recognition. You treat your data as a vector somewhere in a high-dimensional image space. We all know high-dimensionality is bad, so a lower-dimensional subspace is identified, where (probably) useful information is preserved. The Eigenfaces approach maximizes the total scatter, which can lead to problems if the variance is generated by an external source, because components with a maximum variance over all classes aren't necessarily useful for classification (see `http://www.bytefish.de/wiki/pca_lda_with_gnu_octave `_). So to preserve some discriminative information we applied a Linear Discriminant Analysis and optimized as described in the Fisherfaces method. The Fisherfaces method worked great... at least for the constrained scenario we've assumed in our model. - -Now real life isn't perfect. You simply can't guarantee perfect light settings in your images or 10 different images of a person. So what if there's only one image for each person? Our covariance estimates for the subspace *may* be horribly wrong, so will the recognition. Remember the Eigenfaces method had a 96% recognition rate on the AT&T Facedatabase? How many images do we actually need to get such useful estimates? Here are the Rank-1 recognition rates of the Eigenfaces and Fisherfaces method on the AT&T Facedatabase, which is a fairly easy image database: - -.. image:: img/at_database_small_sample_size.png - :scale: 60% - :align: center - -So in order to get good recognition rates you'll need at least 8(+-1) images for each person and the Fisherfaces method doesn't really help here. The above experiment is a 10-fold cross validated result carried out with the facerec framework at: `https://github.com/bytefish/facerec `_. This is not a publication, so I won't back these figures with a deep mathematical analysis. Please have a look into [KM01]_ for a detailed analysis of both methods, when it comes to small training datasets. - -So some research concentrated on extracting local features from images. The idea is to not look at the whole image as a high-dimensional vector, but describe only local features of an object. The features you extract this way will have a low-dimensionality implicitly. A fine idea! But you'll soon observe the image representation we are given doesn't only suffer from illumination variations. Think of things like scale, translation or rotation in images - your local description has to be at least a bit robust against those things. Just like :ocv:class:`SIFT`, the Local Binary Patterns methodology has its roots in 2D texture analysis. The basic idea of Local Binary Patterns is to summarize the local structure in an image by comparing each pixel with its neighborhood. Take a pixel as center and threshold its neighbors against. If the intensity of the center pixel is greater-equal its neighbor, then denote it with 1 and 0 if not. You'll end up with a binary number for each pixel, just like 11001111. So with 8 surrounding pixels you'll end up with 2^8 possible combinations, called *Local Binary Patterns* or sometimes referred to as *LBP codes*. The first LBP operator described in literature actually used a fixed 3 x 3 neighborhood just like this: - -.. image:: img/lbp/lbp.png - :scale: 80% - :align: center - -Algorithmic Description ------------------------ - -A more formal description of the LBP operator can be given as: - -.. math:: - - LBP(x_c, y_c) = \sum_{p=0}^{P-1} 2^p s(i_p - i_c) - -, with :math:`(x_c, y_c)` as central pixel with intensity :math:`i_c`; and :math:`i_n` being the intensity of the the neighbor pixel. :math:`s` is the sign function defined as: - -.. math:: - :nowrap: - - \begin{equation} - s(x) = - \begin{cases} - 1 & \text{if $x \geq 0$}\\ - 0 & \text{else} - \end{cases} - \end{equation} - -This description enables you to capture very fine grained details in images. In fact the authors were able to compete with state of the art results for texture classification. Soon after the operator was published it was noted, that a fixed neighborhood fails to encode details differing in scale. So the operator was extended to use a variable neighborhood in [AHP04]_. The idea is to align an abritrary number of neighbors on a circle with a variable radius, which enables to capture the following neighborhoods: - -.. image:: img/lbp/patterns.png - :scale: 80% - :align: center - -For a given Point :math:`(x_c,y_c)` the position of the neighbor :math:`(x_p,y_p), p \in P` can be calculated by: - -.. math:: - :nowrap: - - \begin{align*} - x_{p} & = & x_c + R \cos({\frac{2\pi p}{P}})\\ - y_{p} & = & y_c - R \sin({\frac{2\pi p}{P}}) - \end{align*} - -Where :math:`R` is the radius of the circle and :math:`P` is the number of sample points. - -The operator is an extension to the original LBP codes, so it's sometimes called *Extended LBP* (also referred to as *Circular LBP*) . If a points coordinate on the circle doesn't correspond to image coordinates, the point get's interpolated. Computer science has a bunch of clever interpolation schemes, the OpenCV implementation does a bilinear interpolation: - -.. math:: - :nowrap: - - \begin{align*} - f(x,y) \approx \begin{bmatrix} - 1-x & x \end{bmatrix} \begin{bmatrix} - f(0,0) & f(0,1) \\ - f(1,0) & f(1,1) \end{bmatrix} \begin{bmatrix} - 1-y \\ - y \end{bmatrix}. - \end{align*} - -By definition the LBP operator is robust against monotonic gray scale transformations. We can easily verify this by looking at the LBP image of an artificially modified image (so you see what an LBP image looks like!): - -.. image:: img/lbp/lbp_yale.jpg - :scale: 60% - :align: center - -So what's left to do is how to incorporate the spatial information in the face recognition model. The representation proposed by Ahonen et. al [AHP04]_ is to divide the LBP image into :math:`m` local regions and extract a histogram from each. The spatially enhanced feature vector is then obtained by concatenating the local histograms (**not merging them**). These histograms are called *Local Binary Patterns Histograms*. - -Local Binary Patterns Histograms in OpenCV ------------------------------------------- - -.. literalinclude:: src/facerec_lbph.cpp - :language: cpp - :linenos: - -The source code for this demo application is also available in the ``src`` folder coming with this documentation: - -* :download:`src/facerec_lbph.cpp ` - -Conclusion -========== - -You've learned how to use the new :ocv:class:`FaceRecognizer` in real applications. After reading the document you also know how the algorithms work, so now it's time for you to experiment with the available algorithms.

The database was used in the context of a face recognition project carried out in collaboration with the Speech, Vision and Robotics Group of the Cambridge University Engineering Department. - -There are ten different images of each of 40 distinct subjects. For some subjects, the images were taken at different times, varying the lighting, facial expressions (open / closed eyes, smiling / not smiling) and facial details (glasses / no glasses). All the images were taken against a dark homogeneous background with the subjects in an upright, frontal position (with tolerance for some side movement). - -The files are in PGM format. The size of each image is 92x112 pixels, with 256 grey levels per pixel. The images are organised in 40 directories (one for each subject), which have names of the form sX, where X indicates the subject number (between 1 and 40). In each of these directories, there are ten different images of that subject, which have names of the form Y.pgm, where Y is the image number for that subject (between 1 and 10). - -A copy of the database can be retrieved from: `http://www.cl.cam.ac.uk/research/dtg/attarchive/pub/data/att_faces.zip `_. - -Yale Facedatabase A -------------------- - -*With the permission of the authors I am allowed to show a small number of images (say subject 1 and all the variations) and all images such as Fisherfaces and Eigenfaces from either Yale Facedatabase A or the Yale Facedatabase B.* - -The Yale Face Database A (size 6.4MB) contains 165 grayscale images in GIF format of 15 individuals.

Believe me... You don't want to do this by hand. So I've prepared you a tiny Python script. The code is really easy to use. To scale, rotate and crop the face image you just need to call *CropFace(image, eye_left, eye_right, offset_pct, dest_sz)*, where: - -* *eye_left* is the position of the left eye -* *eye_right* is the position of the right eye -* *offset_pct* is the percent of the image you want to keep next to the eyes (horizontal, vertical direction) -* *dest_sz* is the size of the output image - -If you are using the same *offset_pct* and *dest_sz* for your images, they are all aligned at the eyes. - -.. literalinclude:: ./src/crop_face.py - :language: python - :linenos: - -Imagine we are given `this photo of Arnold Schwarzenegger `_, which is under a Public Domain license. The (x,y)-position of the eyes is approximately *(252,364)* for the left and *(420,366)* for the right eye. Now you only need to define the horizontal offset, vertical offset and the size your scaled, rotated & cropped face should have. - -Here are some examples: -

In this tutorial I'll show you how to perform gender classification with OpenCV on a set of face images. You'll also learn how to align your images to enhance the recognition results. If you want to do emotion classification instead of gender classification, all you need to do is to update is your training data and the configuration you pass to the demo. - -Prerequisites --------------- - -For gender classification of faces, you'll need some images of male and female faces first. I've decided to search faces of celebrities using `Google Images `_ with the faces filter turned on (my god, they have great algorithms at `Google `_!). My database has 8 male and 5 female subjects, each with 10 images. Here are the names, if you don't know who to search: - -* Angelina Jolie -* Arnold Schwarzenegger -* Brad Pitt -* Emma Watson -* George Clooney -* Jennifer Lopez -* Johnny Depp -* Justin Timberlake -* Katy Perry -* Keanu Reeves -* Naomi Watts -* Patrick Stewart -* Tom Cruise - -Once you have acquired some images, you'll need to read them. In the demo application I have decided to read the images from a very simple CSV file. Why? Because it's the simplest platform-independent approach I can think of. However, if you know a simpler solution please ping me about it. Basically all the CSV file needs to contain are lines composed of a ``filename`` followed by a ``;`` followed by the ``label`` (as *integer number*), making up a line like this: - -.. code-block:: none - - /path/to/image.ext;0 - -Let's dissect the line. ``/path/to/image.ext`` is the path to an image, probably something like this if you are in Windows: ``C:/faces/person0/image0.jpg``. Then there is the separator ``;`` and finally we assign a label ``0`` to the image. Think of the label as the subject (the person, the gender or whatever comes to your mind). In the gender classification scenario, the label is the gender the person has. I'll give the label ``0`` to *male* persons and the label ``1`` is for *female* subjects. So my CSV file looks like this: - -.. code-block:: none - - /home/philipp/facerec/data/gender/male/keanu_reeves/keanu_reeves_01.jpg;0 - /home/philipp/facerec/data/gender/male/keanu_reeves/keanu_reeves_02.jpg;0 - /home/philipp/facerec/data/gender/male/keanu_reeves/keanu_reeves_03.jpg;0 - ... - /home/philipp/facerec/data/gender/female/katy_perry/katy_perry_01.jpg;1 - /home/philipp/facerec/data/gender/female/katy_perry/katy_perry_02.jpg;1 - /home/philipp/facerec/data/gender/female/katy_perry/katy_perry_03.jpg;1 - ... - /home/philipp/facerec/data/gender/male/brad_pitt/brad_pitt_01.jpg;0 - /home/philipp/facerec/data/gender/male/brad_pitt/brad_pitt_02.jpg;0 - /home/philipp/facerec/data/gender/male/brad_pitt/brad_pitt_03.jpg;0 - ... - /home/philipp/facerec/data/gender/female/emma_watson/emma_watson_08.jpg;1 - /home/philipp/facerec/data/gender/female/emma_watson/emma_watson_02.jpg;1 - /home/philipp/facerec/data/gender/female/emma_watson/emma_watson_03.jpg;1 - -All images for this example were chosen to have a frontal face perspective.

And you really don't want scale, rotate & translate the images manually. I have prepared you two Python scripts ``create_csv.py`` and ``crop_face.py``, you can find them in the ``src`` folder coming with this documentation. You'll see how to use them in the :ref:`appendixfgc`. - -Fisherfaces for Gender Classification --------------------------------------- - -If you want to decide whether a person is *male* or *female*, you have to learn the discriminative features of both classes. The Eigenfaces method is based on the Principal Component Analysis, which is an unsupervised statistical model and not suitable for this task. Please see the Face Recognition tutorial for insights into the algorithms. The Fisherfaces instead yields a class-specific linear projection, so it is much better suited for the gender classification task. `http://www.bytefish.de/blog/gender_classification `_ shows the recognition rate of the Fisherfaces method for gender classification. - -The Fisherfaces method achieves a 98% recognition rate in a subject-independent cross-validation. A subject-independent cross-validation means *images of the person under test are never used for learning the model*.
