Abstract
Low bit-rate facial image coding for intended applications to video telephone is presented. The basic principle for this facial image coding is to use 2D image warping techniques in generating successive video frames from a stored master image. Setting global and local grids, the use of attractant/repellant masses, and bilinear mapping for painting a picture are described along with the necessary image analysis for parameter extraction
