WebApr 26, 2024 · The deficiency of 3D segmentation labels is one of the main obstacles to effective point cloud segmentation, especially for scenes in the wild with varieties of different objects. To alleviate this issue, we propose a novel deep graph convolutional network-based framework for large-scale semantic scene segmentation in point clouds … Webgraph construction and GraphCONV, one option is to distribute the vertex points to the CTiles to allow them to compute independently. The distributed CTiles collectively construct the KNN graph and produce the GraphCONV results for a given input point cloud. KNN graph construction can be easily distributed, but GraphCONV is a different story.
