l0 Sparsity for Image Denoising with Local and Global Priors

l0 Sparsity for Image Denoising with Local and Global Priors

We propose a l0 sparsity based approach to remove additive white Gaussian noise from a given image. To achieve this goal, we combine the local prior and global prior together to recover the noise-free values of pixels. The local prior depends on the neighborhood relationships of a search window to h...
