计算峰值旁瓣比和积分旁瓣比的MATLAB程序(A MATLAB program for calculating the peak sidelobe ratio and the integral sidelobe ratio)

本文提出了一个关于图像抠图的方法，它的抠图效果不错，而且作者的主页上提供了MATLAB的源码，可以看一下。(This paper presents a method on the image matting, matting it well, and the author' s home page provides a MATLAB source code, you can see it.)

压缩感知CS——采用小波变换进行稀疏表示，高斯随机矩阵为观测矩阵，重构算法为SL0算法，对256*256的lena图处理，比较原图和SL0算法在不同采样比例(0.74、0.5、0.3)下的重构效果，并各运行50次，比较算法性能PSNR和每次的运行时间 (Compressed sensing CS- using wavelet transform as sparse representation, Gaussian random matrix as the observation matrix and SL0 algorithm as the reconstruction algorithm. Compare lena figure and the reconstruction results using SL0 algorithm at different sampling ratio (0.74,0.50.3),then each runs 50 times, compare the performance of PSNR and each running time)

说明：  example used in Python & VTK
