Evaluation of general image denoising performance on the Kodak24 dataset, specifically measured using the 'Gap to oracle' metric.

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) | Kodak24 |
| Metric | Gap to Oracle |
| Unit | SCALAR |
| Direction | Lower 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

- [Gap to Oracle](<https://www.sota2.com/research/sota/image-denoising-on-kodak24-gap-to-oracle.md?metric=Gap%20to%20Oracle>): Lower is better; unit: SCALAR.
