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

Figure 2

Results of different resolution enhancement methods applied to “Lena” image degraded by Gaussian blur with support size 3×3, standard deviation 0.5, and Gaussian noise with variance 5. (a) One LR image; (b) original image; reconstructed image (c) using LDFP method, (d) using AMM method, and (e) using the proposed method (𝜇=130).
