Evaluation of Image Harmonization performance on the low-resolution (LR) 256x256 test split of the Hday2night subset within the iHarmony4 dataset, using metrics like 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 Hday2night 256x256 LR (test) |
| Metric | PSNR |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 10 of 10 |
| 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/image-harmonization-on-iharmony4-hday2night-256x256-lr-test.md?metric=PSNR>): Higher is better; unit: SCALAR.

- [MSE](<https://www.sota2.com/research/sota/image-harmonization-on-iharmony4-hday2night-256x256-lr-test.md?metric=MSE>): Lower is better; unit: SCALAR.

- [fMSE](<https://www.sota2.com/research/sota/image-harmonization-on-iharmony4-hday2night-256x256-lr-test.md?metric=fMSE>): Lower is better; unit: SCALAR.
