Abstract(in Japanese) (See Japanese page)
Abstract(in English) We aim to realize an image retrieval system for handwritten Japanesehistorical documents, which doesn't require reprinting and revisingprocesses. In this system, a feature graph is used to represent thestructure of a character as well as a string including multiplecharacters. A feature graph of a string to be searched in historicaldocuments is called document graph, while a feature graph of a stringspecified by system users to search is called search graph. Till now, wehave realized a method of generating feature graphs and proposed aretrieval method to search similar subgraphs from a document graphfor a given search graph. In this paper, we propose an improvedmethod of generating feature graphs and present the implementationof similar subgraph retrieval.
