Patent number: 7729536Abstract: An edge detecting method detects edge segments by searching all of the search lines forming an image from an end of the image in a direction perpendicular to the edges. If a line whose edge segment cannot be detected exists, a search is made in all of the search lines from the vicinity of the center of the image toward the end of the image, whereby edge segments are detected. A linear edge is determined from edge segments. A plurality of edge candidates are obtained from the edge segments for all of the search lines, and an optimum candidate is selected from among the edge candidates. Ruled lines are extracted from the source document in the image, and an optimum candidate is selected based on a comparison with a ruled line. As a result, an edge of the source document can be detected with high accuracy even if an image on a background side is unstable, or if materials of the background and the source document are similar.Type: GrantFiled: October 6, 2004Date of Patent: June 1, 2010Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Shinichi Eguchi, Naoko Suzuki, Yutaka Katsumata, Kouichi Kanamoto

Patent number: 7729025Abstract: It is an object of the present invention to improve the compression ratio of a color image and to clearly display the outlines of characters and the like. A hue cluster classifying/unifying unit reduces the number of hue values of each pixel in a color image, based on a hue histogram, allocates the number-reduced hue value to each pixel and classifies pixels with the same hue value into one cluster. Furthermore, the unit unifies clusters whose hue values are below a predetermined value. The unit also traces the outline of a cluster whose size is below a reference value and determines that a cluster that has a lot of change points belongs to a character area. An encoding unit determines the characteristic of each cluster, based on both an area determined by an area determining unit and whether the cluster belongs to a ruled line area or a character area, and encodes pixels in each cluster by a coding method suitable for the characteristic of the cluster.Type: GrantFiled: July 1, 2004Date of Patent: June 1, 2010Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Shinichi Eguchi, Kouichi Kanamoto, Naoko Suzuki, Yutaka Katsumata

Patent number: 7110600Abstract: The invention relates to a document discriminating apparatus and a discriminating method for use in processing documents at financial institutions. A characteristic portion inherent in an optional format is cut out from image data read from a document in the optional format. Color constituents of the cut out image data are analyzed, and a color constituent exhibiting characteristics is selected from the constituents, and a color separation parameter is set for the selected color constituent. Data information is prepared which is related to the image data cut out based upon the color separation parameter. On the other hand, data information is prepared from image data obtained by reading a document to be discriminated based on the color separation parameter. Then, the data information is compared for determination with the data information stored in the document discriminating dictionary unit, whereby the document is discriminated.Type: GrantFiled: September 30, 1999Date of Patent: September 19, 2006Assignee: Fujitsu LimitedInventors: Takayuki Matsui, Yutaka Katsumata, Kazunori Yamamoto, Shinichi Eguchi

Publication number: 20060089809Abstract: When receiving prescribed entry data from an input device, a data entry device issues an authenticate request to a biological authentication device. Upon receipt of the authenticate request, the biological authentication device authenticates the biological information transmitted from the input device by collating it with each piece of biological information stored in a biological authentication DB, and returns the authentication result to the data entry device. The data entry device registers, accesses entry data and executes PKI signature, based on the authentication result transmitted from the biological authentication.Type: ApplicationFiled: May 17, 2005Publication date: April 27, 2006Applicants: FUJITSU LIMITED, FUJITSU FRONTECH LIMITEDInventors: Keizou Satou, Yutaka Katsumata, Takayuki Matsui

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

Publication number: 20050223395Abstract: An application linking technology enables data formatted among many-to-many applications to be communicated. From a window displayed by at least one first application, a necessary information item for an operation of at least one second application is collected. When the collected information items contain items not matching the data format of the second application, data conversion is performed on an unmatched information item to a data format of the second application. A matching information item and a data-converted information item whichever is necessary to the second application is transmitted. A processing result transmitted from the second application is received. Data conversion is performed on an unmatched processing result to a predetermined format when a processing result contains data not matching the predetermined format.Type: ApplicationFiled: September 22, 2004Publication date: October 6, 2005Applicant: FUJITSU LIMITEDInventors: Takayuki Maeta, Yutaka Katsumata, Shinichi Eguchi
