Abstract

A method for extracting facial motion parameters is pro- posed. The method consists of three steps. First, the feature points of the face, selected automatically in the first frame, are tracked in succes- sive frames. Then, the feature points are connected with Delaunay tri- angulation so that the motion of each point relative to the surrounding points can be computed. Finally, muscle motions are estimated based on motions of the feature points placed near each muscle. The experiments showed that the proposed method can extract facial motion parameters accurately. In addition, the facial motion parameters are used to render a facial animation sequence.
