Document Fragments Restoration via Similarity Measurement

The automatic restoration technology of shredded paper is an important branch in computer science. It plays an important role in judicial evidence restoration, the restoration of secret documents, and many other areas. In this article, we establish a similarity measurement model by data mining. This article mainly focuses on Chinese text files with regular cutting. The mathematic model is established and used for restoration, we provide several measurements to achieve the restoration and reduce the workload of manual intervention. At the same time, this article provides a way to restore two-side printing shredded documents. This paper gives experimental results that prove the effectiveness of the proposed method.
