Sparsity for Image Denoising with Local and Global Priors
Figure 1
Noise-free images and denoising results with . (a), (b), (c), and (d) are Lena, Boat, Barbara, and Man, respectively. The first row is the noise-free image. The second row is the noisy image corrupted by additive zero-mean Gaussian noise with , and third row is the denoising result by the proposed approach.
