Segmentation of 3D articulated meshes using shape diameter function and curvature information: Anonymous ICME submission

This paper presents an implicit segmentation approach based upon ideas from morse theory and curvature information. The main contribution consists in partitioning 3D shapes based on Shape-Diameter Function (SDF) which is considered as a continuous scalar function defined on the mesh vertices. The segmentation process is performed according to the values of scalar function associated with each vertex. The SDF allows the segmentation to be invariant to rigid transformation and oblivious to any deformation. After obtaining the initial partition, the detection of region boundaries is improved by using a refinement step based on curvature information. Experiments performed on 3D articulated meshes show that the SDF remains largely pose oblivious.
