专利名称Patent Title
基于视差/运动联合估计的多视点容错编码框架
Multi-viewpoint error resilient coding scheme based on disparity/movement joint estimation
点评:一种基于视差/运动联合估计的多视点容错编码框架,对一个以上视点信息进行视频流传输编码,各个视点以图像组为单位进行编码,每个图像组的最后一帧为关键帧,其余帧为非关键帧。编码框架中引入基于分布式视频编码的差错控制帧。本发明方法比标准的帧内编码具有更好的编码效率,抗差错性能强,即使边信息出现传输差错,仍然能够正确解码,从而增强了多视点视频流的传输鲁棒性。

Comment: The invention discloses a multi-viewpoint error resilient coding scheme based on disparity/movement joint estimation; video stream transmission coding is conducted on more than one viewpoint message; coding is conducted on each viewpoint by taking image groups as unit; and the last frame of each image group is a key frame while others are non-key frames. The coding scheme introduces an error control frame based on distributed video coding. Compared with the standard intra-frame coding, the method has higher coding efficiency and strong error resiliency performance and can still correctly decode even when a side message comes up with transmission error, thereby enhancing the transmission robustness of multi-viewpoint video streams.
