摘    要:碎纸自动拼接技术是图像处理与模式识别领域中的一个较新但是很典型的应用,它是通过扫描和图像提取技术获取一组碎纸片的形状、颜色等信息,然后利用计算机进行相应的处理从而实现对这些碎纸片的全自动或半自动拼接还原。碎纸自动拼接过程一般包括图像预处理和匹配两个主要步骤。形状匹配是碎纸自动拼接过程中的关键技术,但是至今为止,没有很成熟的方法应用于相关工作中。该文给出一种从提取碎纸片轮廓线出发,通过边界准则和面积准则来判断两个轮廓是否匹配来达到碎纸拼接目的的方法,实现了基于计算机辅助的碎纸自动拼接还原。

关 键 词:形状匹配  碎纸自动拼接  面积准则  边界准则

Abstract:Computer-aided paper fragments reassembly is a novel and typical application in the field of computer vision and pattern recognition,which is completed through scan and image extraction techniques to obtain the shape,color and other information.Then the paper fragments are reconstructed based on computer processing. Paper fragments reassembly contains two steps: image preprocessing and matching.Contour-shape matching is one of the key techniques in paper fragments reassembly.But no mature method has been applied to the practical work until now.In order to reconstruct paper fragments automatically or semi-automatically,this paper presents a novel method based on extracting paper fragments outlines and finding the possible matched contours by area rules and boundary rules,and computer-aided automatic paper fragments reassembly is also realized in this paper.
Keywords:Shape matching  Paper fragments reassembly  Area rule  Boundary rule
