Among transform-based image compression methods, the sparsity of transform coefficients is very important for compression performance. To overcome the insufficiency of commonly used DCT and Wavelet transform, we apply the theory of adaptive over-comp

Sparse representation based on over-complete dictionary is a new signal representation theory. Recent activity in this field concentrated mainly on the study of sparse decomposition algorithm and dictionary design algorithm. In this paper, a novel di
