Speckle Noise Reduction via Nonconvex High Total Variation Approach

Figure 3

Denoising results of different methods. (a) shows the noisy images. From left to right, the noise is indicated by , respectively; from (b) to (d), the results are obtained by the proposed method, the TGVSNR method, and the NRSNR method, respectively. Note that all of the denoising results are generated when they reach the highest SNR of their corresponding denoising methods.
