Efficient and Effective Total Variation Image Super-Resolution: A Preconditioned Operator Splitting Approach

Figure 5

Results of different resolution enhancement methods applied to “Cameraman” image degraded by Gaussian blur with support size 3×3, standard deviation 0.5, and Gaussian noise with variance 20. (a) One LR image; reconstructed image (b) using LDFP method, (c) using AMM method, and (d) using the proposed method (𝜇=130).
