ofxFaceRecognizer an addon for openframeworks that implements the face recognition tutorial from the opencv site: http://docs.opencv.org/modules/contrib/doc/facerec/facerec_tutorial.html
It needs opencv 2 or higher.
You extract a face from a video or a static image and feed it in to the recognizer.
At the start the recognizer either loads an already exciting .yml file that contains the recognition model or it creates a new model from the images it finds in the faces folder.
You can select between 3 different recognition methods: eigenfaces, fisherfaces or LBPHFaces.
I am supplying some example faces created by the Tarrlab at Brown University. http://wiki.cnbc.cmu.edu/Face_Place
You notice that the image file names (MF0907_1100_HA.tiff) contain unique IDs to label each person. Each person has more then one image but always the same ID. This ID is used by ofxFaceRecognizer to label each person separately.
I used ofxCv align eyes and crop functions to prepare the images before placing them in the faces folder.
Download the source from GitHub, unzip the folder, rename it from ofxFaceRecognizer-master to ofxFaceRecognizer and place it in your openFrameworks/addons folder.
Or use project generator to build project and then:
modify Project.xcconfig as described in ofxOpenCV2461
add to project-> build settings -> other linker flags ../../../addons/ofxOpenCv/libs/opencv/lib/osx/opencv.a
add to targets-> build settings ->library search paths $(OPENCV_LIBS_PATH)
ofxOpenCV2461 https://github.com/pkmital/ofxOpenCV2461 Requires your project to link against ZLib and OpenCL.

ofxFaceRecognizer has only been tested on osx 10.10 with OF 0.8.4
This addon has been used for "Level of Confidence": https://github.com/antimodular/Level-of-Confidence
