Long short‐distance topology modelling of 3D point cloud segmentation with a graph convolution neural network

IET Computer Vision, 2023
3D point cloud segmentation is a non‐trivial problem due to its irregular, sparse, and unordered data structure. Existing methods only consider structural relationships of a 3D point and its spatial neighbours.
