纸片拼接技术

Paper Splicing Technology

计算机辅助二维碎片自动拼接是模式识别领域中的一个典型问题,它在司法鉴定、文物修复等领域有着广泛的应用。本文对这种二维图像碎片的自动拼接问题展开研究。对于仅纵切的碎片,比较任意两张图片拼接后边界处的相似度来判断碎片之间是否左右相邻;对于纵切加横切的碎片,在纵切模型的基础上考虑了碎片文字所在行的几何特征信息,解决了判断碎片上下相邻的问题;对于双面的碎片,处理方法与纵切加横切类似,仅在对行的几何特征按照相似度进行分组时需要考虑正反面的情况。实验结果验证了方案的有效性。另外,对于文字特点不同于中文的英文碎片建立了改进模型。

The two-dimensional computer-aided automatic stitching debris field of pattern recognition is a typical problem, it has been widely used in forensic, conservators and other fields.We studies the problem of two-dimensional image of this automatic stitching debris started.For only slitting debris, we compare any two images to determine the similarity of the boundary .therefore legitimate for longitudinal cross pieces, based on consideration of the longitudinal model where text fragments geometric characteristics of information line to solve the problem of judging the adjacent upper and lower pieces; for double-sided pieces, similar to the vertical approach Shaver cross, only for the geometric characteristics of the line are grouped according to the similarity to consider when positive and negative situation.Experimental results demonstrate the effectiveness of the program.In addition, .We build an improved English debris model unlike Chinese debris in the text features.
