Evaluation of models performing Human-in-place image synthesis on the official test split of the V-COCO dataset, assessed using metrics including FID, KID, LPIPS, and human preference scores (ELO Rate, HPSv2).

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 | Human-in-place image synthesis |
| Dataset (including any stated split) | V-COCO official (test) |
| Metric | FID |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 8 of 8 |
| 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

- [FID](<https://www.sota2.com/research/sota/human-in-place-image-synthesis-on-v-coco-official-test.md?metric=FID>): Lower is better; unit: SCALAR.

- [KID](<https://www.sota2.com/research/sota/human-in-place-image-synthesis-on-v-coco-official-test.md?metric=KID>): Lower is better; unit: SCALAR.

- [CS](<https://www.sota2.com/research/sota/human-in-place-image-synthesis-on-v-coco-official-test.md?metric=CS>): Higher is better; unit: SCALAR.

- [PSNR](<https://www.sota2.com/research/sota/human-in-place-image-synthesis-on-v-coco-official-test.md?metric=PSNR>): Higher is better; unit: SCALAR.

- [SSIM](<https://www.sota2.com/research/sota/human-in-place-image-synthesis-on-v-coco-official-test.md?metric=SSIM>): Higher is better; unit: PERCENT.

- [LPIPS](<https://www.sota2.com/research/sota/human-in-place-image-synthesis-on-v-coco-official-test.md?metric=LPIPS>): Lower is better; unit: SCALAR.

- [ELO Rate](<https://www.sota2.com/research/sota/human-in-place-image-synthesis-on-v-coco-official-test.md?metric=ELO%20Rate>): Higher is better; unit: SCALAR.

- [HPSv2](<https://www.sota2.com/research/sota/human-in-place-image-synthesis-on-v-coco-official-test.md?metric=HPSv2>): Higher is better; unit: PERCENT.
