Evaluation of 3D Semantic Segmentation performance on the test split of the ScanNet++ dataset, specifically using the 19-class configuration (v2).

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 | 3D Semantic Segmentation |
| Dataset (including any stated split) | ScanNet++ ➜ ScanNet (19 classes) v2 (test) |
| Metric | mIoU |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 8 of 8 |
| 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](<https://www.sota2.com/research/sota/3d-semantic-segmentation-on-scannet-plus-plus-19-classes-v2-test.md?metric=mIoU>): Higher is better; unit: PERCENT.

- [mACC](<https://www.sota2.com/research/sota/3d-semantic-segmentation-on-scannet-plus-plus-19-classes-v2-test.md?metric=mACC>): Higher is better; unit: PERCENT.
