摘要： 在运动补偿内插生成的初始边信息基础上，根据图像的时空相关性，自适应地判断块小波变换方式，传送不同地小波系数辅助解码端生成边信息。实验结果表明，对于不同的视频序列，该算法在一定程度上能有效改进边信息的生成质量。

Abstract: Based on the initial side information generated by MCTI, this paper proposes an algorithm which can decide the way of block wavelet transformation adaptively according to the spatial-temporal correlation of the video sequence and then different wavelet coefficients are transmitted to assist generating the refined side information. Experimental result shows that for different video sequences, the algorithm can efficiently improve the quality of the side information.
Key words: Distributed Video Coding（DVC）, spatial-temporal correlation, wavelet transformation, side information
