Conduct research on the existence and uniqueness of sparse resolution in super-resolution image reconstruction and the relationship of edge feature and smoothing noise of super-resolution image.In order to solve these problems,this paper proposed the mean of adaptive regularization.Combining with joint over-complete dictionary,it realized dynamically adjust the regularization parameter.Through super-resolution image reconstruction experiment,it demonstrates that this algorithm is working efficiently and balances edge features and smoothing noise well,which has high PSNR compared with the traditional algorithm.
