基于分块可压缩传感的图像重建，里面包括contourlet、DWT、DDWT、DCT，图像压缩传感与重建。-Based on the sub-block compressible sensing image reconstruction, which include the Contourlet DWT DDWT,, DCT image compression sensing and reconstruction.

2DDWT程序源代码。同时附上两种典型缺陷图像的例子供测试用。-2 DDWT program source code. At the same time attach two typical examples of defect images for the test.

分块压缩感知，采用SPL进行平滑，包括ct,dct,dwt,ddwt四种稀疏矩阵(Block compression perception, using SPL to smooth, including CT, DCT, DWT, DDWT four sparse matrices)
