Description: Sparse decomposition of image is very high computational complexity of this problem, a block adaptive image sparse decomposition algorithm. The sparse decomposition algorithm based on complexity and computing time to be decomposition of the relationship between image size, to be non-overlapping decomposition of the image into small pieces, then each small image sparse decomposition. According to the complexity of each piece, adaptive sparse decomposition of the end to decide.
