Facial texture updating and compression are crucial in achieving realistic facial animation for low-bit rate coding. We present an efficient way to update and encode facial textures in model-based coding. Differing from traditional methods which update the entire facial texture, we propose a partial texture updating method for realistic facial expression synthesis with facial wrinkles. Experiments on video sequences demonstrate the advantage of the proposed algorithm in keeping transmission cost low while producing realistic expressions
