Evaluation of Portrait photo retouching performance on the test split of the PPR10K Expert c dataset, measured using metrics such as PSNR, ΔEab, PSNR\_HC, and ΔEab\_HC.

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 | Portrait photo retouching |
| Dataset (including any stated split) | PPR10K Expert c (test) |
| Metric | PSNR |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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/portrait-photo-retouching-on-ppr10k-expert-c-test.md?metric=PSNR>): Higher is better; unit: SCALAR.

- [Delta Eab](<https://www.sota2.com/research/sota/portrait-photo-retouching-on-ppr10k-expert-c-test.md?metric=Delta%20Eab>): Lower is better; unit: SCALAR.

- [PSNR\_HC](<https://www.sota2.com/research/sota/portrait-photo-retouching-on-ppr10k-expert-c-test.md?metric=PSNR_HC>): Higher is better; unit: SCALAR.

- [Delta Eab\_HC](<https://www.sota2.com/research/sota/portrait-photo-retouching-on-ppr10k-expert-c-test.md?metric=Delta%20Eab_HC>): Lower is better; unit: SCALAR.
