Line-Skeleton Extraction of 3D Meshes Based on Geometry Segmentation

Skeleton is a fundamental shape feature of 3D mesh, and it can be used in many areas, such as model search, shape analysis, and mesh deformation. This paper presents a novel skeleton extraction method based on mesh segmentation. Firstly, the mesh is cut off by Dijkstras Algorithm and the number of segments N, then the relevant sub-meshes centers are connected to constitute the skeleton. At last, the noise of the skeleton is removed to get the final result. The algorithm is proved robust and fast through the many model demonstrations.
