A Novel Surface Skeleton Based Segmentation Method for Voxel Shapes

In this paper, a new method is proposed for voxel shape segmentation which uses 3D surface skeleton to segmenting a shape into part-like structure. Firstly, a cut is defined for segmenting a shape, and this cut is partly smooth, tight, and its orientation is defined by the local symmetric axis of a shape. Next, with analysis of the cut space, potential segmenting cuts are detected. Finally, we use a variety of 3D shapes to test the usability of our methods. From our experiments, our method has topology and geometry based invariant.
