Abstract
We propose a real-time retrieval method for document images in various languages. In this method, queries are images of documents captured by a web-camera. The document images corresponding to the queries are retrieved from the document image database in real time. Since we have already proposed a document image retrieval method for English documents, the proposed method is an extension for retrieval of documents in various languages. In the previous English document image retrieval method, only centroids of word regions are used as feature points. Therefore it cannot be applied to some languages including Japanese and Chinese due to no separation between words and periodic arrangements of characters. In the proposed method, additional features are introduced to realize real-time retrieval for document images in various languages.
