Evaluation of Image Enhancement performance on the test split of the NPE dataset, measured using NIQE and PIQE.

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 Enhancement |
| Dataset (including any stated split) | NPE (test) |
| Metric | NIQE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 9 of 9 |
| 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

- [NIQE](<https://www.sota2.com/research/sota/image-enhancement-on-npe-test.md?metric=NIQE>): Lower is better; unit: SCALAR.

- [PIQE](<https://www.sota2.com/research/sota/image-enhancement-on-npe-test.md?metric=PIQE>): Lower is better; unit: SCALAR.
