A Facial Animation Module of Mpeg-4 System Based On Vrml97 For Virtual And Natural Scene Integration

Abstract

In this paper, the architecture of facial animation module of MPEG-4 is presented and implemented. MPEG-4 is an object based international compression standard established by ISO, and this standard has many significant features that make it very suitable for Internet applications of variable or very low bit rate. The MPEG-4 standard specifies definition and animation of human faces and bodies. For human faces, the Facial Definition Parameters (FDPs) and the Facial Animation Parameters (FAPs) are defined for representation and animation on any facial model. In this paper, an approach that animates facial expression and mouth shape in talking is first generated by modifying a generic head model. To animate realistic facial expressions of the 3D head model, key frames of facial expressions are calculated from photographs of expression and mouth. The system can provide real-time speech –driven talking capability.
