Evaluation of image colorization performance on the test split of the standard ImageNet dataset, measured using human perception metrics like percentage of human-labeled real images.

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 | Colorization |
| Dataset (including any stated split) | ImageNet (test) |
| Metric | FID |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 11 of 11 |
| 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/colorization-on-imagenet-test.md?metric=FID>): Lower is better; unit: SCALAR.

- [Human Labeled Real Percentage](<https://www.sota2.com/research/sota/colorization-on-imagenet-test.md?metric=Human%20Labeled%20Real%20Percentage>): Higher is better; unit: PERCENT.

- [PSNR](<https://www.sota2.com/research/sota/colorization-on-imagenet-test.md?metric=PSNR>): Higher is better; unit: SCALAR.

- [SSIM](<https://www.sota2.com/research/sota/colorization-on-imagenet-test.md?metric=SSIM>): Higher is better; unit: PERCENT.

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

- [Colorful Score](<https://www.sota2.com/research/sota/colorization-on-imagenet-test.md?metric=Colorful%20Score>): Higher is better; unit: SCALAR.

- [Delta Colorful Score](<https://www.sota2.com/research/sota/colorization-on-imagenet-test.md?metric=Delta%20Colorful%20Score>): Higher is better; unit: SCALAR.
