PAIRWISE LINKAGE FOR POINT CLOUD SEGMENTATION [PDF]
ISPRS Annals of Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 In this paper, we first present a novel hierarchical clustering algorithm named Pairwise Linkage (P-Linkage), which can be used for clustering any dimensional data, and then effectively apply it on 3D unstructured point cloud segmentation. The P-Linkage clustering algorithm first calculates a feature value for each data point, for example, the density ...
