Efficient and Effective Total Variation Image Super-Resolution: A Preconditioned Operator Splitting Approach
Figure 8
Results of different resolution enhancement methods applied to “Fingerprint” image degraded by Gaussian blur with support size , 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 ().
