视频压缩效率的提高很大程度上取决于用于传输残差图像的信息量的减少,而残差图像的特性对分析和讨论视频残差图像编码有重大的意义。对可伸缩视频编码中的运动补偿时域滤波残差图像特性从能量非.平稳特性、时空相关特性和频率特性进行了研究。并给出了实验结果和分析。
The improvement of video coding is depended on how to reduce the use of motion compensation prediction error information, so it is important for effectively coding the residual image to study the property of residual image. In this paper, the property of residual image is researched based on Motion Compensation Yemporal Filtering (MCTF) in scalable video coding from the energy non-stationary, temporal-spatial correlation and frequency property. Finally, the experiment results are given and analyzed in the paper.
