INTERSPEECH 2004 - ICSLP
A method is described for video-based tracking and analysis of talking heads. Although dots on the face and head are tracked now, clean faces will be tracked once a satisfactory optical flow technique is found. The analysis consists of decomposing the head and face motion components into a common mode and the residual, thus eliminating the need for complex marker tracking and head correction of face motion.
