Image restoration based on nonlocal total variation
A novel nonlocal total variation method for image restoration was proposed. The proposed method extended the conventional total variation to a novel nonlocal model and made full use of the structure protection within the nonlocal patches to further improve the restoration quality. In addition to the proposed nonlocal total variation model, the operator was introduced to compact the objective function, and then solved it alternatively with Splitting technique to obtain high accuracy. The experiment results shows that the proposed method outperform the conventional methods on both of the evaluation and visualization.
