point cloudlocal volume after compressionLVACprobability distributionPoint cloud is a kind of important dataset in robot navigation and environment understanding. Most clustering algorithms were designed with certain assumptions and it is difficult to find natural clustering in a point cloud which contains ...
Many useful point cloud clustering algorithms for extracting a single target from a point cloud scene have been published. These methods are mainly divided into two categories: clustering algorithms based on distance information and clustering algorithms based on density information3,4,5. However, the...
Guo et al. (2023) proposed a plant point cloud segmentation method that integrates deep learning algorithms with clustering algorithms, incorporating the Adaptive Self-Attention for Point Cloud Processing (ASAP) attention module into the PointNet++ model. This enhancement to the ASAP-PointNet model ...
Clustering algorithms42 were widely used to detect similar patterns within a point cloud, also known as clusters based on different features43, comprising spatial position44, points normal vector45, and density of points within point clouds46. While research efforts have focused on detecting ...
