I have followed this tutorial http://docs.opencv.org/modules/contrib/doc/facerec/tutorial/facerec_video_recognition.html for have face recognition with OpenCV. The source code is easy but does not works well. For example I obtain the same prediction for me, my sister and my brother.
Have you got experiences with OpenCV and face recognition? Have you got any suggestion for have the best of the results with face recognition? Which is the tipical error in percentual with face recognition applications?
