Evaluation of Gaussian Denoising performance on the 512x768 test split of the Kodak24 dataset, measured using Mean PSNR and Mean gap to oracle (dB).

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 | Gaussian Denoising |
| Dataset (including any stated split) | Kodak24 512×768 (test) |
| Metric | Mean PSNR |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 3 of 3 |
| 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

- [Mean PSNR](<https://www.sota2.com/research/sota/gaussian-denoising-on-kodak24-512x768-test.md?metric=Mean%20PSNR>): Higher is better; unit: SCALAR.

- [Mean gap to oracle (dB)](<https://www.sota2.com/research/sota/gaussian-denoising-on-kodak24-512x768-test.md?metric=Mean%20gap%20to%20oracle%20(dB)>): Lower is better; unit: SCALAR.
