Evaluation of Semantic Segmentation performance on the validation split of the Mapillary Vistas dataset, focusing on results aggregated across 65 defined categories, reporting metrics such as small-sample (s.s.) and medium-sample (m.s.) Mean IoU (mIoU).

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 | Semantic segmentation |
| Dataset (including any stated split) | Mapillary Vistas 65 categories (val) |
| Metric | mIoU (medium-sample) |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 3 of 3 |
| 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

- [mIoU (medium-sample)](<https://www.sota2.com/research/sota/semantic-segmentation-on-mapillary-vistas-65-categories-val.md?metric=mIoU%20(medium-sample)>): Higher is better; unit: PERCENT.

- [mIoU (small-sample)](<https://www.sota2.com/research/sota/semantic-segmentation-on-mapillary-vistas-65-categories-val.md?metric=mIoU%20(small-sample)>): Higher is better; unit: PERCENT.
