A Modified Iterative Alternating Direction Minimization Algorithm for Impulse Noise Removal in Images

Figure 10

Mural images after removing impulse noise-like artifacts. (a1), (a2) are original images; (b1), (b2) are results of median filtering; (c1), (c2) are results of total variation denoising; (d1), (d2) are results of the wavelet-based sparse representation denoising; (e1), (e2) are results of the proposed method.
