Evaluation of Anomaly Segmentation performance on the test split of the RoadAnomaly v1 dataset, reporting metrics including AUC, AP, and FPR95.

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 | Anomaly segmentation |
| Dataset (including any stated split) | RoadAnomaly v1 (test) |
| Metric | AP |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 12 of 12 |
| 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

- [AP](<https://www.sota2.com/research/sota/anomaly-segmentation-on-roadanomaly-v1-test.md?metric=AP>): Higher is better; unit: PERCENT.

- [AUC](<https://www.sota2.com/research/sota/anomaly-segmentation-on-roadanomaly-v1-test.md?metric=AUC>): Higher is better; unit: PERCENT.

- [FPR95](<https://www.sota2.com/research/sota/anomaly-segmentation-on-roadanomaly-v1-test.md?metric=FPR95>): Lower is better; unit: PERCENT.
