The existing Wyner-Ziv video coding systems have large rate-distortion performance gap comparing to traditional H.26x or MPEG based systems. One of the primary reasons for the performance gap is that the side information generation schemes in these systems use motion based linear extrapolation or interpolation methods which result in low quality side information. We present a side information generation scheme that utilizes both the motion information and the statistical similarity derived from signal statistic features. Results have shown that this scheme can generate side information about 1~2 dB better than H.264’s motion compensated prediction.
