摘要 视频压缩效率的提高在很大程度上取决于如何减少用于传输运动补偿预测误差的信息量,即如何有效地编码视频帧差图像。首先对帧差图像的统计特性进行了分析,然后以基于DCT、基于小波和基于HVS等帧差图像编码为线索,对视频帧差图像编码的进展情况进行了分析和讨论,最后对视频帧差图像编码的进一步发展进行了展望。 The improvement of video coding is depended on how to reduce the use of motion compensation prediction error information,which is also called Displaced Frame Difference（DFD）.This paper first analyzes the DFD,then gives analysis and discussion for DFD along with the coding based on DCT,wavelet and HVS of DFD.In addition,the future development of DFD coding is also analyzed and conjectured in the paper.
