Evaluation of Image Denoising performance on the test split of the BSD68 dataset, reporting PSNR scores specifically for noise levels sigma=15, sigma=25, and sigma=50.

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 |
| Dataset (including any stated split) | BSD68 (test) |
| Metric | PSNR (σ=25) |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 26 of 26 |
| 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 (σ=25)](<https://www.sota2.com/research/sota/image-denoising-on-bsd68-test-psnr-multi-sigma.md?metric=PSNR%20(%CF%83%3D25)>): Higher is better; unit: SCALAR.

- [PSNR (σ=15)](<https://www.sota2.com/research/sota/image-denoising-on-bsd68-test-psnr-multi-sigma.md?metric=PSNR%20(%CF%83%3D15)>): Higher is better; unit: SCALAR.

- [PSNR (σ=50)](<https://www.sota2.com/research/sota/image-denoising-on-bsd68-test-psnr-multi-sigma.md?metric=PSNR%20(%CF%83%3D50)>): Higher is better; unit: SCALAR.
