Reconstruction of rippedup documents was important for judicial authentication,cultural relic reconstruction and military information acquisition,etc.An approach for the reconstruction of regularly rippedup documents was proposed. Firstly, the line spacing of the fragments was automatically extracted. Secondly, meanshift algorithm was adapted to cluster all the fragments. Thirdly, for each cluster, the similarity matrix was constructed based on the grayscale of the edges of the fragments. Lastly, the document with genetic algorithm was reconstructed.Reconstruction of rippedup documents is important for judicial authentication,cultural relic reconstruction and military information acquisition,etc.In this paper,we propose an approach for the reconstruction of regularly rippedup documents.
