中文说明：简单的压缩感知代码，用小波变进行换稀疏分解，然后又用随机测量矩阵进行测量，以及用OMP重构算法恢复图像，代码可以运行处结果，有原始图像和重建以后的图像，适用于初学者对压缩感知的过程进行了解。
English Description：
Simple compressed sensing code, using wavelet transform commutation sparse decomposition, and then measured using random measurement matrix, as well as restore the image, the code can be run at the results with OMP reconstruction algorithm, the original image and the reconstructed image after for early scholars to understand the process of compressed sensing.
