Image restoration using spatially variant hyper-Laplacian prior

The heavy-tailed hyper-Laplacian prior has been successfully applied in image restoration tasks, in which the unified distribution is adopted for the whole image. However, the gradient distribution of natural image is reasonably assumed to be spatially variant, e.g., gradient distribution of the reg...
