Abstract In this report, we propose a real-time image retrieval system using a web camera for documents in various languages. This system takes camera-captured document images as queries and find the corresponding document images from a database. This is an extension of our real-time image retrieval for English documents. In the English document image retrieval system, centroids of word regions are used as feature points to describe documents. These feature points are effective since English has clear between word gaps. On the other hand, in some languages including Japanese and Chinese, words are not separated. Therefore alternative feature points such as centroids of character regions are required. In the proposed method, this problem is solved by using the additional features extracted from character regions.
