Uncertainty-aware Prototype Learning with Variational Inference for Few-shot Point Cloud Segmentation
Yifei Zhao, Fanyu Zhao, Yinsheng Li
Few-shot 3D semantic segmentation aims to generate accurate semantic masks for query point clouds with only a few annotated support examples. Existing prototype-based methods typic…
