压缩感知demo

压缩感知demo CSdemo，图片压缩感知的实例程序！运行即可

img=im2one（imread（‘G:\matlab program\标准图像\Cameraman.bmp‘））;
img=im2one（imresize（img[64 64]））;
[ab]=size（img）;


%物体化为列向量
T=reshape（img[a*b1]）;

%生成随机测量矩阵
M=2000;%压缩后大小
mes=rand（Ma*b）;

%测量
S=mes*T;

%重构选用l1-TV算法参数简单，恢复效果好，不需要额外的稀疏基，但是耗时久，快速重构可以用TVAL3;
%SAMP算法也可以用，但是需要额外的稀疏基
%重构算法可以暂时不用了解

x0=mes\S;
rec=tvqc_logbarrier（x0 mes [] S 0.011e-42）;

%评价与显示
imgre=reshape（rec[ab]）;
imgre=im2one（（imgre））;
cc=corrcoef（imgreimg）;
psnr=IMGSNR（imgimgre）;
figureimshow（imgre）;
