摘　　要：压缩感知是最近几年理论化的信号采集和处理理论。研究证明,某些信号可远少于奈奎斯特频率采样点数据无失真恢复原始数据。综述了压缩感知理论的基本原理、应用步骤和实现方法,着重讲述了压缩感知在图像和视频编码中的应用,并介绍了实验室进行的两方面相关研究工作,最后指出了压缩感知在图像和视频编码领域的应用前景。Compressed sensing is the lastest signal acquisition and processing theory, which denotes that certain signals can be recovered from far fewer samples than the traditional Nyquist theory suggests. In this paper, the basic principals, application steps and realization functions of compressed sensing are introduced, especially the application in image and video coding area, and related researches are introduced to denotes that compressed sensing has application prospects in image and video coding.
