For fine-grained 3D vision tasks where point-wise features are essential, like semantic segmentation and 3D detection, our network achieves higher prediction accuracy than the existing networks using the nearest neighbor interpolation or the normalized trilinear interpolation with the zero-padding or the octree-padding scheme.

Although unsupervised feature learning has demonstrated its advantages to reducing the workload of data labeling and network design in many fields, existing unsupervised 3D learning methods still cannot offer a generic network for various shape analysis tasks with competitive performance to supervised methods.
Ranked #2 on 3D Semantic Segmentation on PartNet
3D Point Cloud Linear Classification 3D Semantic Segmentation
1 code implementation • CVPR 2020 • Yu-Qi Yang, Shilin Liu, Hao Pan, Yang Liu, Xin Tong
Surface meshes are widely used shape representations and capture finer geometry data than point clouds or volumetric grids, but are challenging to apply CNNs directly due to their non-Euclidean structure.
Ranked #29 on Semantic Segmentation on ScanNet (test mIoU metric)
