Super-resolution image reconstruction algorithm based on double sparse representation

Aiming at the current requirements of image reconstruction in the actual applications, by studying the super-resolution image reconstruction and the theory of sparse representation, this paper proposes a super-resolution image reconstruction algorithm based on double sparse representation. This paper also makes some comparative experiments with the algorithm based on single sparse representation. The experiment results show that the reconstruction results of our algorithm are better than the results of super-resolution image reconstruction algorithm based on single sparse presentation.
