... Point cloud Recognition, requiring only scene-level class tags as supervision.
... WyPR can detect and segment objects in point cloud data without access to any spatial labels at training time. We demonstrate its efficacy using the ScanNet and S3DIS datasets, outperforming prior state of the art on weakly-supervised segmentation by more than 6% mIoU.
... WyPR outperforms standard approaches and establishes strong baselines for future work.
