Fig. 11From: 3D shape representation with spatial probabilistic distribution of intrinsic shape keypointsConstructing a local “complete graph.” a Point cloud of the object. The neighbors around a point are highlighted inside the circle. b All the nodes within a sphere of radius (r=3.5× point cloud resolution) are connected to the parent node. c A “complete graph” is constructed within a sphere, where every node is connected to another one by a unique edgeBack to article page
