摘要

This paper presents a novel skeleton pruning approach based on angle maps. The angle map of the test object is a representation of the object contour's angles during a 2D empirical mode like decomposition (EMD-like). The intrinsic mode functions produced by the EMD like decomposition are used to compose the angle map of the object contour. This angle map has very good properties for obtaining the object's skeleton. The experimental results demonstrate that the obtained skeletons match to hand-labelled skeletons provided by human subjects, even in the presence of significant noise and shape variations, cuts and tears, and have the same topology as the original skeletons.
