Comparison of MDI to HMI super-resolution results.
| Metric | LDM RES (Ours) | Enhance (Díaz Baso & Asensio Ramos 2018) | Progressive (Rahman et al. 2020) |
|---|---|---|---|
| PSNR ↑ | 29.23 ± 8 | 30.02 ± 9 | 29.71 ± 8 |
| SSIM | 0.8 ± 0.05 | 0.9 ± 0.03 | 0.8 ± 0.04 |
| LPIPS ↓ | 0.08 ± 0.03 | 0.16 ± 0.04 | 0.16 ± 0.04 |
| FID ↓ | 0.04 ± 0.01 | 0.7 ± 0.2 | 2.3 ± 0.3 |
| Unsigned Magnetic Flux (%) | 18 ± 13 | 27.5 ± 26.7 | 28.5 ± 15.0 |
| AR Size (%) | 25 ± 18 | 35 ± 69 | 36 ± 38 |
Notes. The symbol ↓ indicates that a lower value is preferable for the metric, while ↑ indicates that a higher value is preferable. SSIM ranges between −1 and 1. Unsigned magnetic flux and AR size are expressed as percentage variations. References: Díaz Baso & Asensio Ramos (2018), Rahman et al. (2020).
