Speckle Noise Reduction via Nonconvex High Total Variation Approach

Figure 4

Local zoomed denoising results. From (a) to (d), the number of looks the denoising results refer to is indicated by , respectively. In (a), (b), (c), and (d), from left to right, we list the clean image, the denoising result of the proposed method, the denoising result of the TGVSNR method, and the denoising of the NRSNR method.
