利用压缩感知对图像进行处理 先用小波变换生成矩阵，再利用正交匹配追踪算法，在对图像进行稀疏处理后进行正交匹配追踪 -Orthogonal matching pursuit algorithm for image processing First generated using wavelet transform matrix orthogonal matching pursuit, sparse processing image

小波变换矩阵生成 代码主要实现了2D-DWT的矩阵生成，只需输入维度以及分解层数即可生成相应的小波变换矩阵-Wavelet transform matrix generating code mainly realize the 2D-DWT matrix generation, simply enter the dimensions and number of layers to generate the corresponding decomposition wavelet transform
