Research Based on Stitching Technology of Scrapped Paper

This paper mainly make stitching technology of character in scrapped paper of printed file carry on research, which puts forward a stitching method in the light of character and image with multi-feature information in scrapped paper, mainly considering stitching same line character generally possesses similar horizontal projection region and projection center, it adopts human-computer interaction to semi-automatic stitching. First, we make image of scrapped paper binarization and small area filtering (with the exception of the boundary), after characters clustering, we utilize matching degree of pixels information of the left and right edges to make vertical stitching. This method can better tackle stitching and restoration of scrapped paper characters whose edge with segmented character. The scraped papers provided by the national undergraduate mathematical modeling contest were conducted experiment; the results indicate that this method is effective, with strong real-time property, robustness.
