Surface Representation for Point Clouds
CVPR 2022 Oral Presentation (5.0%) [PDF] [Supp] [ArXiv] [Code]
Haoxi Ran, Jun Liu, Chengjie Wang
A novel representation of point clouds to explicitly depict the very local structure, including Triangular RepSurf and Umbrella RepSurf inspired by triangle meshes and umbrella curvature in computer graphics.
Rethinking Network Design and Local Geometry in Point Cloud: A Simple Residual MLP Framework
ICLR 2022 (32.9%) [PDF] [ArXiv] [OpenReview] [Code]
Xu Ma, Can Qin, Haoxuan You, Haoxi Ran, Yun Fu
A novel perspective on the task of point cloud analysis by introducing a pure-MLP, simple yet effective residual network, called PointMLP.
Learning Inner-Group Relations on Point Clouds
Haoxi Ran, Wei Zhuo, Jun Liu, Li Lu
A scalable and efficient relation-based module, called group relation aggregator, to compute a feature of a group based on the aggregation of the features of the inner-group points weighted by geometric relations and semantic relations.
