Evaluation of Anomaly Segmentation performance on the test split of the Fishyscapes Lost & Found v1 dataset, measured using metrics like 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) | Fishyscapes Lost & Found v1 (test) |
| Metric | FPR95 |
| Unit | PERCENT |
| Direction | Lower is better |
| Results loaded | 18 of 18 |
| 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

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

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

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