TopoSeg: Topology-aware Segmentation for Point Clouds

Proceedings of the Thirty-First International Joint Conference on Artificial Intelligence, 2022
Point cloud segmentation plays an important role in AI applications such as autonomous driving, AR, and VR. However, previous point cloud segmentation neural networks rarely pay attention to the topological correctness of the segmentation results. In this paper, focusing on the perspective of topology awareness.

Graph Regulation Network for Point Cloud Segmentation

IEEE Transactions on Pattern Analysis and Machine Intelligence
In point cloud, some regions typically exist nodes from multiple categories, i.e., these regions have both homophilic and heterophilic nodes. However, most existing methods ignore the heterophily of edges during the aggregation of the neighborhood node features, which inevitably mixes unnecessary information of heterophilic nodes and leads to blurred ...

Point Cloud Segmentation Based on Radial Reflection

2009
This paper introduces a novel 3D segmentation algorithm, which works directly on point clouds to address the problem of partitioning a 3D object into useful sub-parts. In the last few decades, many different algorithms have been proposed in this growing field, but most of them are only working on complete meshes. However, in robotics, computer graphics,
