Abstract

The model-based image coding might be the potential method for very/ultra low bit rate visual communications. However, some problems still remain for video practice, such as a finer wireframe 3-D model, precise rule for facial expressions analyzing, and automatic feature points extraction for real time application, etc. This paper proposes a feasible scheme of model-based image coding based on a deformable model which would be suitable for very/ultra low bit rates transmission. Meanwhile, some key techniques, such as automatic face feature point extraction based on a priori knowledge for real time applications and the method of AUs separation of a face on various expressions, is given.
