Abstract结合压缩感知理论和传统的视频编解码技术,提出了一种基于压缩感知理论的视频编解码器。其编码过程可看成是将高维信号投影到低维空间的过程,解码过程不再是传统方式下的编码的逆过程,而可看作是求解欠定方程组的过程。该编解码器结构比较简单,不仅所需图像的样本数很少,样本数可根据不同的编码模式进行选择,而且能获得较高的压缩比和较好的重构图像质量。
Other AbstractIn this paper,a new video codec which combines compressive sensing theory and some critical ideas of traditional video codecs is proposed.The encoder works as a projector,which projects a high dimensional signal to a low dimensional domain,while the decoder which is no longer the inverse of encoder works for the solution of underdetermined equations.Compared with traditional codecs,the new codec is simpler.Not only samples needed in the new codec are fewer than in traditional codecs and the number of samples can he changed according to the encoding mode, but also high compression ratio and good quality of reconstructed video arc obtained.
