Patent number: 6721451Abstract: A character line is identified with a keyword included in the relevant logical element of a keyword dictionary, and the identification result is output to a “keyword identification part” to store the result. All the character lines processed through a “division process part” are output to a “tagging modification part” to replace tags so that there is no logically inconsistent in adjacent character lines, when tags given to adjacent character lines are in logically inconsistent as a combination of tags. A character line to which an appropriate tag may not be given in the “tagging modification part” is output to an “indecisive tag estimation part” where an appropriate tag is estimated and is given with reference to a tag adjacent the character lines. The process in the “indecisive tag estimation part” is applied to all the character lines, and repeated till there is no replacement of tags.Type: GrantFiled: August 30, 2000Date of Patent: April 13, 2004Assignee: Kabushiki Kaisha ToshibaInventor: Yasuto Ishitani

Patent number: 5506918Abstract: A document skew detection apparatus for facilitating the recognition of the contents of a printed document includes an image processing section for generating a binary coded image of the document containing a plurality of black picture elements distributed among white picture elements to depict pure text lines and non-text portions of the document. The binary coded image is then modified so that certain ones of the black picture elements satisfying a predetermined condition are integrated together to generate a coarse document image being decreased in resolution. The apparatus also includes an image extraction section for extracting from the document image a local image region containing pure text lines occupying an almost entire area thereof, and skew detection section for detecting a direction of orientation of the text lines of the local region, and for determining an angular difference between a detected direction and a reference direction as a skew angle of the printed document.Type: GrantFiled: December 23, 1992Date of Patent: April 9, 1996Assignee: Kabushiki Kaisha ToshibaInventor: Yasuto Ishitani
