Evaluation of Image Harmonization performance on the High Resolution test split of the HCOCO subset within the iHarmony4 dataset, using metrics including MSE, fMSE, and PSNR.

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 Harmonization |
| Dataset (including any stated split) | iHarmony4 HCOCO High Resolution (test) |
| Metric | MSE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 7 of 7 |
| 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

- [MSE](<https://www.sota2.com/research/sota/image-harmonization-on-iharmony4-hcoco-high-resolution-test.md?metric=MSE>): Lower is better; unit: SCALAR.

- [fMSE](<https://www.sota2.com/research/sota/image-harmonization-on-iharmony4-hcoco-high-resolution-test.md?metric=fMSE>): Lower is better; unit: SCALAR.

- [PSNR](<https://www.sota2.com/research/sota/image-harmonization-on-iharmony4-hcoco-high-resolution-test.md?metric=PSNR>): Higher is better; unit: SCALAR.
