说明：  实现了图像的分块操作，比较方便初学者使用(It is the program for image blocking.)

基于小波变换的正交匹配追踪算法及其应用先介绍了压缩感知的基本原理以及理论模型，然后详细阐述了匹配追踪(Ⅷ)以及正交匹配追踪(()脚) 两种重构算法，进而提出了基于小波变换的正交匹配追踪算法(wOⅧ)，即先将信号经过单层小波变换，保留信号的 低频部分，只对高频稀疏部分进行压缩，然后利用正交匹配追踪算法进行重构，最后对低频及处理后得到的高频部分 进行小波反变换得到重构信号。(Based on orthogonal wavelet transform matching tracking algorithm and its application to the basic principles and theoretical models compressed sensing, and then elaborated matching pursuit (Ⅷ) and orthogonal matching pursuit )
