2、 Hunan 410073,China)ABSTRACT:Computer-aided paper frag ments reassembly is a novel and typicalapplication in the field of co mputervision and pattern recognition,which is completed through scan and i mage extraction techniques to obtain the shape,color and other infor mation.Then the paper fragments
3、 are reconstructed based on co mputer processing.Paper fragments reasse mbly contains two steps:i mage preprocessing andmatching.Contour-shapematching is one of the keytechniques in paper fragments reasse mbly.But no maturemethod has been applied to the practicalwork untilnow.Inorderto reconstruct p
4、aper frag ments auto matically or se m i-auto matically,this paper presents a novelmethod basedon extracting paper fragments outlines and finding the possible matched contours by area rules and boundary rules,and computer-aided auto matic paper fragments reasse mbly is also realized in this paper.KE
