Patent number: 9245168Abstract: An authentication apparatus performs identity authentication by comparing and matching image information of a palm captured by a sensor unit with a preliminarily registered template. A surface information correcting unit corrects concavity/convexity of a palm surface for surface information that allows the concavity/convexity thereof to be evaluated. The surface information is extracted by a surface information extraction unit from the image information obtained by capturing the palm. When the surface information is not corrected by the surface information correcting unit or not used for authentication by an authentication unit even after correction, the authentication apparatus newly obtains image information of the palm. Correction by the surface information correcting unit reduces opportunities for the authentication apparatus to perform notification to guide the palm to a proper posture.Type: GrantFiled: July 26, 2013Date of Patent: January 26, 2016Assignee: FUJITSU FRONTECH LIMITEDInventors: Tomoharu Suzuki, Takehiro Sekikawa, Maki Yabuki, Shinichi Eguchi

Patent number: 9111152Abstract: In a verification object specifying apparatus that specifies a verification object for biometric authentication, a biometric information acquisition unit acquires biometric information from a biometric information source part. An abnormality detection unit detects an abnormal portion in the biometric information source part based on the biometric information. A verification object specifying unit determines whether biometric information located in the abnormal portion is to be included in a verification object, and specifies biometric information to be used as the verification object based on the determination result. The verification object specifying apparatus causes a registration unit to register the biometric information as registration information when serving as a registration apparatus, and causes a verification unit to verify the biometric information against registration information when serving as a verification apparatus.Type: GrantFiled: December 28, 2012Date of Patent: August 18, 2015Assignee: FUJITSU FRONTECH LIMITEDInventor: Maki Yabuki

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: 6052480Abstract: A character box extracting unit extracts a line forming a character box. Then, the character box intersection calculating unit calculates the intersection of the character box with a character pattern. An intersection corresponding unit associates intersections with each other based on the directional property of character lines, distance between the character lines, etc. An in-box character extracting unit extracts a virtual image according to the association information between the intersections. A character size evaluating unit obtains from an optional character string an average character size of a character including the virtual image, and extracts a true character pattern by removing a redundant virtual image based on the average character size.Type: GrantFiled: January 11, 1999Date of Patent: April 18, 2000Assignee: Fujitsu LimitedInventors: Maki Yabuki, Satoshi Naoi

Patent number: 6005976Abstract: In an image extraction system, an extracting part for extracting wide lines, an extracting part for extracting narrow lines and a frame detector detect a frame from a pattern which is extracted by a connected pattern extracting part. An attribute adder adds attributes of a character (graphic and symbol inclusive), frame, and a contact pattern of the character and frame to a partial pattern, and a separating part separates the frame from the contact pattern. An intersection calculator calculates intersections of the character and frame, and the calculated intersections are associated by an intersection associating part. An interpolator obtains a character region within the frame and interpolates this region based on the associated intersections. A connection confirming part confirms a connection of the pattern with respect to the extracted character pattern, and patterns confirmed of their connection are integrated in a connected pattern integrating part to thereby extract the character.Type: GrantFiled: July 30, 1996Date of Patent: December 21, 1999Assignee: Fujitsu LimitedInventors: Satoshi Naoi, Maki Yabuki, Atsuko Asakawa
