摘要：
This paper deals with spatial prediction in Wyner-Ziv video coding. Coding structures that extend DPCM to the distributed coding scenario are presented. Using a high resolution approximation, the optimal prediction filters for these structures are derived. The resulting predictive coder is employed to compress the DC component of a transform based distributed video coding system. Preliminary results show rate-distortion gains compared to the case without spatial prediction.
