# Part Segmentation on ShapeNet Parts Source: [Part Segmentation on ShapeNet Parts]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:11:06.291Z Evaluation of Part Segmentation performance on the ShapeNet Parts dataset, reporting pIoU and mpIoU metrics. 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 | Part Segmentation | | Dataset (including any stated split) | ShapeNet Parts | | Metric | mpIoU | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 32 of 32 | | 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 - [mpIoU](): Higher is better; unit: PERCENT. - [pIoU](): Higher is better; unit: PERCENT. ## Recorded results | Method | mpIoU | Result date | Report paper | | --- | --- | --- | --- | | PointCNN | 84.6 | Not recorded | 68fa65041e209131cea07e8d | | PointCNN | 84.6 | Not recorded | 68fa66351e209131cea0ec63 | | SPLATNet | 83.7 | Not recorded | 68fa65041e209131cea07e8d | | SplatNet | 83.7 | Not recorded | 68fa66351e209131cea0ec63 | | SSCN | 83.3 | Not recorded | 68fa65041e209131cea07e8d | | SGPN | 82.8 | Not recorded | 68fa65041e209131cea07e8d | | SGPN | 82.8 | Not recorded | 68fa66351e209131cea0ec63 | | ShellNet | 82.8 | Not recorded | 68fa66351e209131cea0ec63 | | Pd-Network | 82.7 | Not recorded | 68fa65041e209131cea07e8d | | DGCNN | 82.3 | Not recorded | 68fa65041e209131cea07e8d | | DGCNN | 82.3 | Not recorded | 68fa66351e209131cea0ec63 | | KCNet | 82.2 | Not recorded | 68fa65041e209131cea07e8d | | KCNet | 82.2 | Not recorded | 68fa66351e209131cea0ec63 | | SyncSpecCNN | 82 | Not recorded | 68fa65041e209131cea07e8d | | SyncCNN | 82 | Not recorded | 68fa66351e209131cea0ec63 | | PointNet++ | 81.9 | Not recorded | 68fa65041e209131cea07e8d | | PointNet++ | 81.9 | Not recorded | 68fa66351e209131cea0ec63 | | PCNN | 81.8 | Not recorded | 68fa65041e209131cea07e8d | | PCNN | 81.8 | Not recorded | 68fa66351e209131cea0ec63 | | SpiderCNN | 81.7 | Not recorded | 68fa65041e209131cea07e8d | | SpiderCNN | 81.7 | Not recorded | 68fa66351e209131cea0ec63 | | RSNet | 81.4 | Not recorded | 68fa65041e209131cea07e8d | | RSNet | 81.4 | Not recorded | 68fa66351e209131cea0ec63 | | SO-Net | 81 | Not recorded | 68fa65041e209131cea07e8d | | 3DmFV-Net | 81 | Not recorded | 68fa65041e209131cea07e8d | | SO-Net | 81 | Not recorded | 68fa66351e209131cea0ec63 | | 3DmFV-Net | 81 | Not recorded | 68fa66351e209131cea0ec63 | | PointNet | 80.4 | Not recorded | 68fa65041e209131cea07e8d | | PointNet | 80.4 | Not recorded | 68fa66351e209131cea0ec63 | | Kd-Net | 77.4 | Not recorded | 68fa65041e209131cea07e8d | | KdNet | 77.4 | Not recorded | 68fa66351e209131cea0ec63 | ### PointCNN mpIoU: 84.6.
