Abstract

An algorithm for segmenting 2D shapes into parts is described. The segmentation is constructed from the local symmetry axes of the shape. The local symmetry axes are determined by analyzing the local symmetries of the level curves of a function which is the solution of an elliptic PDE. The segmentation has the structure of a directed graph. The shapes need not be presmoothed and the algorithm may be applied to a complex scene consisting of many objects.
