Evaluation of 4x Super-resolution models tested on the ImageNet 1K dataset rendered at 256x256 resolution, specifically corrupted with Gaussian noise corresponding to sigma=0.05. Metrics include PSNR, SSIM, and KID.

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 | 4x super-resolution |
| Dataset (including any stated split) | ImageNet 1K noise sigma=0.05 256x256 |
| Metric | PSNR |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 6 of 6 |
| 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/4x-super-resolution-on-imagenet-1k-noise-sigma-0-05-256x256.md?metric=PSNR>): Higher is better; unit: SCALAR.

- [SSIM](<https://www.sota2.com/research/sota/4x-super-resolution-on-imagenet-1k-noise-sigma-0-05-256x256.md?metric=SSIM>): Higher is better; unit: PERCENT.

- [KID](<https://www.sota2.com/research/sota/4x-super-resolution-on-imagenet-1k-noise-sigma-0-05-256x256.md?metric=KID>): Lower is better; unit: SCALAR.
