Fractured Surfaces Matching for Reassembling Broken Objects
Guohua Geng · Journal of Chinese Computer Systems · 2013
The paper presents a fractured surfaces matching algorithm.Firstly,feature points are selected from all surface points according to their shape index.Secondly few er and effective salient matching point pairs are obtained through first comparing feature point's shape index and then surface patches.With salient points as the center every fractured surface is divided into several patches w hich is described by its number of feature points and a 3D histogram.For all feature points except central point of every patch w e no longer looking for their similar points.Finally w e use exhaustive search method constrained by triangle similarity to match fractured surfaces.Experimental results show the algorithm is capable of dealing w ith full and partial fractured surfaces matching problem.
