PSR: Unified Framework of Parameter-Learning-Based MR Image Superresolution

Figure 2

Image test sample. The comparison of reconstructed result with different balance parameter λ is shown in Table 1, where the superresolution is 1 : 2. The first column in Table 1 is the change of the balance parameter. The data in the table is the corresponding PSNR value. The results are plotted in Figure 3. (a) Head, (b) ankle, (c) carotid artery, (d) knee, and (e) neck.
