A Fast High-Order Total Variation Minimization Method for Multiplicative Noise Removal

Figure 6

A small portion of Lena image is emphasized to show the difference of the four methods for Test 2. (a) Original image. (b) Noisy image with 𝐿=3. (c) Noisy image with 𝐿=13. (d) Restored image by the AA method for 𝐿=3. (e) Restored image by the HNW method for 𝐿=3. (f) Restored image by the MIDAL method for L=3. (g) Restored image by our method for 𝐿=3. (h) Restored image by the AA method for 𝐿=13. (i) Restored image by the HNW method for 𝐿=13. (j) Restored image by the MIDAL method for 𝐿=13. (k) Restored image by our method for 𝐿=13.
