Evaluation of Semantic Segmentation performance on the validation split of the Pascal VOC dataset, specifically configured to exclude the background class (VOC 20 variant).

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) | Pascal VOC without background 20 (val) |
| Metric | Pixel Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| 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

- [Pixel Accuracy](<https://www.sota2.com/research/sota/semantic-segmentation-on-pascal-voc-without-background-20-val.md?metric=Pixel%20Accuracy>): Higher is better; unit: PERCENT.
