Denoising comparison. (a) Result using the seislet thresholding method. (b) Removed noise corresponding to (a). (c) Local similarity between (a) and (b). (d) Removed noise using the rank-reduction method. (e) Removed noise corresponding to (d). (f) Local similarity between (d) and (e). (g) Result using the proposed method. (h) Removed noise using the proposed method. (i) Local similarity between (g) and (h).
