Patent number: 8577147Abstract: An objective is to eliminate dotted lines in a character box in image data to increase the character recognition rate. There are some cases in which a dotted line candidate cannot be extracted due to many overlapping parts of dotted lines and characters or due to a blurry part in a dotted line. In such cases, the position of a dotted line candidate is estimated referring to features such as the interval, length, width, etc. of a dotted line candidate in the same character box (or in a character box for another relevant item), and image data of the estimated position and image data of a previously extracted dotted line (or a reference dotted line) are compared to determine whether or not they are an identical dotted line.Type: GrantFiled: June 1, 2011Date of Patent: November 5, 2013Assignee: Fujitsu Frontech LimitedInventors: Shohei Hasegawa, Shinichi Eguchi, Hajime Kawashima, Koichi Kanamoto, Hiroki Inoue, Maki Yabuki, Katsutoshi Kobara

Patent number: 7016535Abstract: Collation can be carried out at a high speed without reducing the accuracy thereof, whereby processing of identifying documents is accurately performed at a high speed. To this end, characteristic data of a predetermined pattern is registered in advance. Characteristic data in a first area greater than an area of the predetermined pattern registered in advance in an image to be identified is compared and collated with characteristic data of the predetermined pattern. A second area smaller than the first area is cut out from the first area based on the result of comparison, so that characteristic data of an image in the second area is compared and collated with the characteristic data of the predetermined pattern, thus making it possible to identify the predetermined pattern contained in the image based on the result of comparison.Type: GrantFiled: November 16, 2001Date of Patent: March 21, 2006Assignee: Fujitsu LimitedInventors: Toshiyuki Waida, Shinichi Eguchi, Kouichi Kanamoto, Maki Yabuki, Koichi Chiba, Katsutoshi Kobara, Osamu Sato, Kazunori Yamamoto, Yutaka Katsumata

Patent number: 6694065Abstract: An image collating apparatus and an image collating method, in which a document larger than an image reader can be collated using a preregistered image even in the case where the document is read by the image reader, are disclosed. The image of the document read by the image reader is collated sequentially with the document images of different sizes preregistered in a data base. The document size is determined from the document image input from the image reader. In the case where the document size is smaller than the preregistered image size, the preregistered image is retrieved in accordance with the document size, so that the document features are extracted and matched between the read document image and the registered image set in size to each other, thereby collating the read image with the preregistered image.Type: GrantFiled: December 11, 2000Date of Patent: February 17, 2004Assignee: Fujitsu LimitedInventors: Katsutoshi Kobara, Shinichi Eguchi, Kouichi Kamamoto, Maki Yabuki, Koichi Chiba, Toshiyuki Waida, Kazunori Yamamoto, Yutaka Katsumata

Patent number: 6556701Abstract: Disclosed are a method of and an apparatus for extracting a dotted line from an binary image of a document, and a storage medium thereof. The isolated points are extracted from the binary image. The isolated points configuring a candidate of the dotted line are extracted based on a positional relationship between the extracted isolated points. A validity of the isolated points configuring the candidate of the dotted line is checked. The dotted line from a positional relationship between groups of the extracted isolated points of the candidate of the dotted line. The dotted line can be thereby precisely extracted even if some isolated points are lost due to an. under-density of the image etc.Type: GrantFiled: October 20, 1999Date of Patent: April 29, 2003Assignee: Fujitsu LimitedInventors: Koichi Chiba, Shinichi Eguchi, Kouichi Kanamoto, Katsutoshi Kobara, Maki Tabuki, Yutaka Katsumata

Patent number: 6549662Abstract: Characters of data on a document are recognized by automatically determining the definitions of characters of the data from the arrangement of character strings of the data. Character strings on the document are extracted by reading the document, and headers and data on the document are distinguished from each other by determining the positional relationship between the character strings. Character attributes of the data are determined by recognizing characters of the character strings of the headers using a header recognition dictionary. Characters of the character strings of the data are recognized according to the determined character attributes of the data. Since character attributes of the data are determined from recognized characters of the headers after the headers and the data are distinguished from each other from the layout on the document, it is possible to enter automatically the character attributes of the data.Type: GrantFiled: May 27, 1998Date of Patent: April 15, 2003Assignee: Fujitsu LimitedInventors: Katsutoshi Kobara, Shinichi Eguchi, Yoshihiro Nagano, Hideki Matsuno, Koichi Chiba, Yutaka Katsumata
