一张图片是之前用摄像机采集的,另一张图片是经过离散沃尔什变换再量化编码压缩后又解压所得,能看出区别吗?呵呵。flik.m是原图,newflik.m是新图。
附上所有MATLAB源程序,有兴趣的话,你也可以用这几个程序对自己的照片“加工”一番。以下6个程序分别保存为6的m文件,文件名与下面给出的一致。待“加工”图片应该存放在Matlab的Work目录下。(Before a picture is collected by the camera, another picture is the result of discrete Walsh transform and then re-quantization coding compression decompression income, you can see the difference? Ha ha. flik.m is the image, newflik.m is a new map. MATLAB source code attached to all interested, you can also use these procedures on their own photo processing of something. The following six procedures were saved as 6 m file, the file name is given with the following consensus. To be processing picture should be stored in Matlab s Work directory.)

wavelet-cs
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 )
