破碎文件的拼接在司法物证复原、历史文献修复以及军事情报获取等领域都有着重要的应用。传统上，拼接复原工作需由人工完成，准确率较高，但效率很低。特别是当碎片数量巨大，人工拼接很难在短时间内完成任务。随着计算机技术的发展，人们试图开发碎纸片的自动拼接技术，以提高拼接复原效率。

1.1破碎纸片为同一页印刷文字文件的碎纸机仅纵切得到的，建立碎纸片拼接复原模型和算法，并针对附件1、附件2给出的中、英文各一页文件的碎片数据进行拼接复原。如果复原过程需要人工干预，则写出干预方式及干预的时间节点。复原结果以图片形式及表格形式表达。

1. 2破碎纸片为碎纸机既纵切又横切的得到，建立碎纸片拼接复原模型和算法，并针对附件3、附件4给出的中、英文各一页文件的碎片数据进行拼接复原。如果复原过程需要人工干预，则写出干预方式及干预的时间节点。复原结果表达要求同上。

1. 3从现实情形出发，破碎纸片为双面打印文件的碎纸片，建立碎纸片拼接复原模型。附件5给出的是一页英文印刷文字双面打印文件的碎片数据。并就附件5的碎片数据给出拼接复原结果，结果表达要求同上。-Splicing broken file evidence in judicial rehabilitation, restoration and historical documents to obtain military intelligence and other areas have important applications. Traditionally, the splicing work to be done by hand restoration, high accuracy, but low efficiency. Especially when a huge amount of debris, artificial stitching difficult to complete tasks in a short time. With the development of computer technology, people trying to develop automatic stitching scraps of paper, in order to improve the recovery efficiency of splicing. 1.1 Broken pieces of paper shredders on the same page as printed text documents obtained by slitting only establish stitching scraps of paper recovery model and algorithms, and Annex 1, Annex 2 illustrates, each page file fragmentation data for English splicing recovery. If the recovery process requires human intervention, it is time to write the node intervention and intervention. Recovery results in picture form and table forms of expression. Broken p
