Facial tracking with head pose estimation in stereo vision

Facial tracking is a key step for face modeling, coding and animation. In this paper we present a facial tracking method in stereo vision. We use an efficient representation of 3D face motion, consisting of global head motion and local facial deformation. Stereo vision is utilized to measure 3D coordinates of the face, the global and local motion parameters of the tracked face is solved respectively. From the 3D space to the left and right image space we employ reprojection to realize 3D tracking. Experimental results of our method are given to demonstrate its performance.
