Extraction of Representative Structure of Decorative Character Images

Extracting structure information from decorative character images is a challenging problem in the field of character recognition. The structure information of a decorative character image can be represented by a graph. However, the topologies of graphs are different even if they are the ones of the same character, because of various decorations. In this paper, we propose a method to extract a representative graph of decorative character images. The proposed method extracts graphs from decorative character images, obtains common nodes in a character and iteratively integrates graphs into one common supergraph using common nodes. To show the validly of the proposed method, experiments are carried out using decorative character images.
