This is a video I took couple of years ago. Which is about a system I developed for the facial recognition using 2D and & 3D LPB features. it's extensible and with nice UI. the LBP feature could be improved significantly, and it's good feature fore facial expression description. The video only shows you a very basic prototype system. But to some sense, it shows that LBP+SVM is a good scheme for such application.
