Evaluation of Image Colorization performance on the test split of the LEARCH 22 dataset, typically measured using AuC CMF and AMT Labeled Real metrics.

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 Colorization |
| Dataset (including any stated split) | LEARCH 22 (test) |
| Metric | AuC CMF |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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

- [AuC CMF](<https://www.sota2.com/research/sota/image-colorization-on-learch-22-test.md?metric=AuC%20CMF>): Higher is better; unit: PERCENT.

- [AMT Labeled Real](<https://www.sota2.com/research/sota/image-colorization-on-learch-22-test.md?metric=AMT%20Labeled%20Real>): Higher is better; unit: PERCENT.
