Evaluation of Open-set Semantic Segmentation performance on the Lost & Found FS dataset, reporting metrics such as IoU and mean F1.

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 | Open-set semantic segmentation |
| Dataset (including any stated split) | Lost & Found FS |
| Metric | IoU |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| 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

- [IoU](<https://www.sota2.com/research/sota/open-set-semantic-segmentation-on-lost-and-found-fs.md?metric=IoU>): Higher is better; unit: PERCENT.

- [Mean F1](<https://www.sota2.com/research/sota/open-set-semantic-segmentation-on-lost-and-found-fs.md?metric=Mean%20F1>): Higher is better; unit: PERCENT.
