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

Figure 7

Denoised Barbara images with 50% salt-and-pepper noise. (a1), (b1), and (c1) are initial guide image using median filtering, total variation, and wavelet, respectively; (d1) original image; (a2), (b2), (c2), and (d2) are denoising results of the proposed method using (a1), (b1), (c1), and (d1) as the initial guide image, respectively.
