- The original implementation is from : https://github.com/guptapraful/niqe
- There were big discrepancy between Matlab NIQE score and the original python implementation :
- Extracted clean image's mean & cov from matalb (data/clean_image_parameters.mat) and added minor modifications
- After modification (NIQE score below:)
| Image | Python version | Matlab (NIQE) |
|---|---|---|
| bikes.bmp | 3.298 | 3.231 |
| bikes_distorted.bmp | 8.057 | 8.037 |
| parrots.bmp | 3.778 | 3.789 |
| parrots_distorted.bmp | 5.607 | 5.613 |
