视点切换是交互式多视点视频应用需要解决的难题之一,该文为此提出一种交互式多视点视频的编码方案。通过消除预测帧之间的相关性,改善视点切换的性能,以共享关键帧和时-空预测编码方式,在时间和空间上去除多视点视频数据的冗余,提高编码效率。该方案不增加任何辅助数据,即可在任意的P帧上进行快速视点切换,具有极低的视点切换延时,并且兼顾了编码效率和单一视点的解码代价。采用H.264/AVC编码器实现该方案,并得到满意的测试结果。
Viewpoint switching is one of the problems to be solved in interactive multi-view video applications. In this paper, an interactive multi-view video coding scheme is proposed. By eliminating the correlation between the prediction frames and improving the performance of the viewpoint switching, the redundancy of the multi-view video data is removed in time and space by sharing the key frames and the time-space prediction coding method, thereby improving the coding efficiency. The scheme can achieve fast view switching in any P frame without any additional data, and has very low viewpoint switching delay, and takes into account the coding efficiency and decoding cost of a single viewpoint. Using H.264 / AVC encoder to achieve the program, and get satisfactory test results.
