摘要
分析了分布式信源编码理论和分布式压缩感知理论,应用差分编码思想到分布式压缩感知视频编解码器,采用差分联合稀疏模型(DJSM),设计并实现了一种差分分布式压缩感知视频编解码器(DDCS-VC);它具有结构简洁,实现复杂度较低,码流可分级传输等特点,可广泛应用与无线传感网或泛在网络中的多点分布式视频应用场合。
This paper analyzes the distributed source coding theory and the muhi-signal compressive sensing theory, desig- ning a new differencing distributed compressive sensing video CODEC and realizing through combining the typical three distributed compressive sensing video CODEC with the ideas for differencing joint sparse model. This video CODEC with the features of simple structure, low computational complexity, and stream hierarchical transmission, can be widely used in different kinds of wireless sensing networks or ubiquitous networks.
