this file is written for the image reconstruction, which uses the DCT method. In order to get the image, the DCT matrix is used as the sparse matrix, the observable matrix is Gaussian, the method of reconstruction is OMP. As the algorithm is easy, we just split the image into small size (16X16), and the area which is not covered by the image will set to be zero, and the reconstruction is done block by block.
