Evaluation of Real-world Image Super-Resolution models using the ImageNet dataset rendered at 256x256 resolution, assessed using metrics including PSNR, LPIPS, FID, NIQE, MUSIQ, MANIQA, and CLIPIQA.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Real-world Image Super-Resolution |
| Dataset (including any stated split) | ImageNet 256x256 |
| Metric | PSNR |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 8 of 8 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [PSNR](<https://www.sota2.com/research/sota/real-world-image-super-resolution-on-imagenet-256x256.md?metric=PSNR>): Higher is better; unit: SCALAR.

- [LPIPS](<https://www.sota2.com/research/sota/real-world-image-super-resolution-on-imagenet-256x256.md?metric=LPIPS>): Lower is better; unit: SCALAR.

- [FID](<https://www.sota2.com/research/sota/real-world-image-super-resolution-on-imagenet-256x256.md?metric=FID>): Lower is better; unit: SCALAR.

- [NIQE](<https://www.sota2.com/research/sota/real-world-image-super-resolution-on-imagenet-256x256.md?metric=NIQE>): Lower is better; unit: SCALAR.

- [MUSIQ](<https://www.sota2.com/research/sota/real-world-image-super-resolution-on-imagenet-256x256.md?metric=MUSIQ>): Higher is better; unit: SCALAR.

- [MANIQA](<https://www.sota2.com/research/sota/real-world-image-super-resolution-on-imagenet-256x256.md?metric=MANIQA>): Higher is better; unit: SCALAR.

- [CLIPIQA](<https://www.sota2.com/research/sota/real-world-image-super-resolution-on-imagenet-256x256.md?metric=CLIPIQA>): Higher is better; unit: SCALAR.
