Abstract
The invention discloses a face recognition method that reconstructs a 3D face model from a single face image, synthesizes a set of face images under different conditions (such as pose, light . . . ) via the 3D face model, feeds the set of face images under different conditions to the face recognition classifier for training, and making intermediate decisions whether to-be identified individual from a series of video frames is a legal system user by the face recognition classifier. Moreover, the method not only recognizes legal system users, but also rejects imposters, a function inspired by the idea of LLE. Finally, better reliability can be achieved by fusing temporal intermediate decisions.
