Abstract
For facial video coding/decoding in mobile communication, a 2D/3D model-based system was proposed: (1)Online appearance model and cylinder head model were combined to track 3D facial motion in particle filter; (2)3D facial animation was produced combining parameterized model and muscular model; (3)3D hair was synthesized by hair detection and 3D hair model; (4)3D coding/decoding of foreground and 2D coding/decoding of background were stitched. At ultra-low bit-rate, the object experiment confirmed the advantage between coding efficiency and decoding quality of it, and the between subjects experiment indicated the suitability of subjective face identification by it.
