Evaluation of image denoising performance specifically targeting Salt & Pepper Noise on the test split of the Urban100 dataset, reporting PSNR, SSIM, and LPIPS.

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 | Image Denoising (Salt & Pepper Noise) |
| Dataset (including any stated split) | Urban100 (test) |
| Metric | PSNR |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 32 of 32 |
| 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/image-denoising-salt-and-pepper-noise-on-urban100-test.md?metric=PSNR>): Higher is better; unit: SCALAR.

- [SSIM](<https://www.sota2.com/research/sota/image-denoising-salt-and-pepper-noise-on-urban100-test.md?metric=SSIM>): Higher is better; unit: SCALAR.

- [LPIPS](<https://www.sota2.com/research/sota/image-denoising-salt-and-pepper-noise-on-urban100-test.md?metric=LPIPS>): Lower is better; unit: SCALAR.
