This paper presents a complete dictionary and algorithms over a combination of sparse representation of image de-noising algorithm first noise image into small image blocks and orthogonal matching pursuit algorithm for sparse small image blocks in the initialization of the image decomposition and over-complete dictionary Use a dictionary learning algorithm to be updated over-complete dictionary repeat the process to obtain the final image and the reconstructed image sparse representation
