In the research of historical Japanese documents, examination of kaou monograms plays a very important role for specifying the author’s identity and the genuineness of the document. This work aims to develop a kaou search/browsing system usable via World Wide Web (WWW), for aiding the research of historical documents. One of the requirements to the system is that the kaou images should be retri...

With the increasing number of documents that are available in digital form, also the number of digital historical documents is increasing (Berkvens, 2001). It cannot be assumed that standard IR systems perform well on historical documents: historical texts differ from modern texts in three ways (Hüning, 1996; Van Der Horst and Marschall, 1989): (a) vocabularies have changed, (b) spelling has ch...

In China, efforts are being made to preserve historical documents in the form of digital data so that they can be effectively used while being protected. Stitching technology is expected to play a role in these efforts as it can be used to divide a large historical document into multiple areas, scan those areas using a compact contactless scanner, and seamlessly connect the resulting images. Si...
