A Modified Iterative Alternating Direction Minimization Algorithm for Impulse Noise Removal in Images
Images are often corrupted by impulse noise. In this paper, an alternating direction minimization with continuation algorithm is modified and iteratively used to remove the impulse noise in images by exploring its self-similarity. A patch-based nonlocal operator and sparse representation are married...
