Non-Convex High Order Total Variation With Overlapping Group Sparsity Denoising Model Under Cauchy Noise
It is widely known that the total variation regularization model preserves the edges well in the restored images but has some staircase effects. We consider using non-convex high-order total variation and overlapping group sparsity as a hybrid regularization to present a new denoising model. The pro...
