Evaluation of Free-road Segmentation performance on the validation split of the perciv-scenes-2 dataset, measured using Intersection over Union metrics for free space (IoUfree) and occupied regions (IoUocc).

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 | Free-road Segmentation |
| Dataset (including any stated split) | perciv-scenes-2 (val) |
| Metric | IoU Free Space |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 2 of 2 |
| 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 Free Space](<https://www.sota2.com/research/sota/free-road-segmentation-on-perciv-scenes-2-val.md?metric=IoU%20Free%20Space>): Higher is better; unit: PERCENT.

- [IoU Occupied](<https://www.sota2.com/research/sota/free-road-segmentation-on-perciv-scenes-2-val.md?metric=IoU%20Occupied>): Higher is better; unit: PERCENT.
