Research on Fragments Reassembly Based on Feature of Chinese Character and Template Matching

The technology of fragments reassembly is widely employed in many scientific fields, such as judicial evidence recovery, restoration of historic documents, accessing to military intelligence and so on, which is based on computer vision and pattern recognition. In this paper, an efficient method for Chinese fragments reassembly is presented. The proposed reassembly method is based on the feature of line spacing and Chinese characters’ feature that the same font has the same height. Considered the feature of English characters that English letters are connected components, this paper proposes a model for English fragments reassembly, which is based on template matching. Using the proposed methods on digitally scanned images of actual fragments of paper image prints has verified the robustness and reliability of two models.
