Graph pyramid construction on a point cloud
Webconvolution on point clouds, while PointCNN [25] applies Euclidean convolution after applying a learned transforma-tion. Finally, SPLATNet [43] encodes point clouds on a lattice and performs bilateral convolution. All these works aim to apply convolution-like operations to point clouds and extract local geometric features.

We argue that the organization of 3D point clouds can be efficiently captured by a structure called superpoint graph (SPG), derived from a partition of the scanned scene into …
WebDec 9, 2024 · RandLA-Net processes large-scale 3D point clouds in a single pass, without requiring any pre/post-processing steps such as voxelization, block partitioning, or graph construction. 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.
