Abstract :
A pixel-domain Wyner-Ziv residual video coding scheme is presented. In this scheme, based on the statistical distribution characteristics of the residual signal, an adaptive binary-to-Gray code converting process is designed so that virtual channel noises can be lowered over bit-planes. Through simulations, it is shown that the best case performs better than the DISCOVER scheme as well as the worst case.
