Abstract :
In this paper, we propose a new wavelet video coding based on MCTF-WZ through introducing Wyner-Ziv coding, which is a new coding structure. Low and high frequency frames in temporal domain are encoded through the distinct coding manner, where the former is encoded by the BISK algorithm after spatial analysis. But the latter is encoded by two distinct ways according to the correlation between the reference and current frames. In this way, regions which have high correlations are coded by Wyner-Ziv coding, and regions which only have short correlations are coded by BISK after discrete wavelet transform. The coding efficiency of this scheme is close to H.264 and MC-EZBC or even better.
