摘要
研究了压缩感知视频编码方法。与传统方法相比,压缩感知视频的采样率更低。基于压缩感知技术,对视频帧的一维感知和二维感知分别进行研究和分析。由于考虑到视频帧行与行之间的相关性,二维感知更适合视频编码。同时,实验结果表明二维视频感知对高冗余度的视频序列重建效果更加优越。
In this paper, a video coding method with the technology of compressive sensing is proposed. This method is proved to be able to perform better than the conventional sampling in the way of using lower sampling rate. Based on compressed sensing technology, 1D and 2D sensing methods for the frame of video signal are studied. For the reasons of taking into account the correlation between the row of the frame, the 2D sensing is found to be more feasible for the code of the video frame. From the experimental results, it is found that the 2D sensing video theory is more suitable for the high redundant video.
