Single-image super-resolution reconstruction based on global non-zero gradient penalty and non-local Laplacian sparse coding
Global non-zero gradient penalty is developed to reconstruct the edge component. Non-local Laplacian sparse coding is developed to reconstruct the texture component. Global and local function is developed to further improve the image?s quality.
