ABSTRACT:
The present invention discloses a method of automatically detecting and tracking a face by an electronic capturing device that alternatively uses a face detecting algorithm to quickly locate a face in a frame based on a skin color model and a face tracking algorithm to locate a face in subsequent frames by a nonparametric technique and a mean shift algorithm. If the face tracking algorithm cannot track and locate a face correctly, the face detecting algorithm will be used again to detect a face position in another new frame until the face position is located successfully, and then the face tracking algorithm will be used again for detecting and locating the face position in subsequent frames. After this method has detected a face position, a variable focal lens is used to slowly and smoothly refocus the frame including a face region, so as to obtain a clear face image.
