Details of Research: Document Image Understanding

Document Understanding System Incorporating with OCR

We developed a document image understanding system incorporating with character recognition. I think this was the first system in the world which could work in the practical environment.

Though the system could handle the table form documents only, it was really the first operable machine and we exhibited it in 1984.

Document Understanding Using FDL (Form Definition Language)

To make the document understanding universal, the usage of a formal language description for the knowledge on form. We first realized such a system. It is regrettable that many researchers believes FDL is only applicable to fixed forms because FDL describes the documents using absolute values. This is misunderstanding. FDL adopts a generic representation of documents.

I regret to inform the reader that Mr. Higashino passed away early in 1997. He was young and brighted, so we have expected that his contribution to the field would have been enormous and stimulated many researchers.
