In this paper we propose a method for implementing a high-level interface for the synthesis and animation of animated virtual faces that is in full compliance with MPEG-4 specifications. This method allows us to implement the Simple Facial Object profile and part of the Calibration Facial Object Profile. In fact, starting from a facial wire-frame and from a(More)
—An efficient algorithm is proposed to exploit the facial animation parameter (FAP) interpolation modality specified by the MPEG-4 standard in order to allow very low bit-rate transmission of the animation parameters. The proposed algorithm is based on a comprehensive analysis of the cross-correlation properties that characterize FAPs, which is here(More)
In this paper the complete framework of a software package for real-time animation of 3D facial models according to the MPEG-4 specifications is described. The focus is mainly on the algorithmic solution that has been adopted for scaling the polygon mesh to a level of complexity suited to the specific hw/sw profile of the platform that hosts the decoder.(More)
