压缩感知及其在图像压缩中的应用

分析了压缩感知的原理与应用,对相关的重要算法进行了系统阐述,并将压缩感知方法应用于图像压缩,提出了基于压缩感知的图像压缩系统框架.实验结果表明,在只保留50%采样点的条件下,该系统仍能获得较好的图像恢复质量.;The basic idea of compressive sensing is introduced，and then the important algorithm is surveyed．Its application in image coding systemis studied．An image coding systembased on compressive sensing is proposed．The experimental results show that the good performance is acquired with only 50%co efficient sretained
