Patent number: 8615129Abstract: When an operator starts a pattern separation extraction tool, an input screen is displayed on the display device. The operator can choose and designate any one of document image data within the storage device through the input screen. The document image that is chosen by the operator is displayed on the display device. The operator can choose and designate a color sample by a drag operation on the document image that is displayed on the display device. If the operator inputs the designation to finish the designation of a color sample through the input device after designating some color samples, the pattern separating extraction device generates and outputs the image data that consists of one print pattern for each of the print patterns included in the document image chosen by the operator.Type: GrantFiled: December 21, 2007Date of Patent: December 24, 2013Assignee: Fujitsu LimitedInventor: Misako Suwa

Patent number: 7903874Abstract: A set of straight lines that associate a top parallel geodesic projection positioned at an upper end with a bottom parallel geodesic projection positioned at a lower end, among sets of parallel geodesic projections, is extracted as a set of ruled-line candidate projections as a search target of a set of ruled line projections. A deviation of neighborhood, which is a distance between a cross ratio vector of the ruled-line candidate projection and a cross ratio vector of a neighboring line obtained by shifting the ruled-line candidate projection by a predetermined interval, is calculated for each ruled-line candidate projection. A set of straight lines having the smallest sum total of deviations of neighborhood, in the set of straight lines, which do not intersect with each other, among the sets of ruled-line projection candidates is extracted as a set of ruled line projections by continuous dynamic programming.Type: GrantFiled: August 20, 2007Date of Patent: March 8, 2011Assignee: Fujitsu LimitedInventors: Katsuhito Fujimoto, Misako Suwa, Hiroaki Takebe, Satoshi Naoi

Patent number: 7471848Abstract: A projection set of geodesic lines which are parallel with each other on a curved surface of a paper face is extracted from an image in which a paper face has been imaged by an image-pickup device, using the paper face contents as a clue; and also a projection set of ruling lines which form a ruled surface corresponding to the curved surface of the paper face is extracted from the projection set of geodesic lines. Then, the curved surface of the paper face is estimated from the projection set of the geodesic lines and ruling lines, and distortion of the image is corrected based on this curved surface of the paper face. If this is done, correspondence with various types of diverse distortions becomes possible, and distortion correction can be performed even when only one part of the paper face appears in the image.Type: GrantFiled: February 22, 2006Date of Patent: December 30, 2008Assignee: Fujitsu LimitedInventors: Katsuhito Fujimoto, Misako Suwa, Hiroaki Takebe, Satoshi Naoi

Patent number: 7280693Abstract: A document information input apparatus detects a position and an attribute of an area of a real document to be input designated by a user with high accuracy. Based on the detected position and attribute, the document information input apparatus recognizes an image of the area as text information by performing recognition processes suitable for the detected attribute such as character recognition, table recognition and a figure process. Then, the document information input apparatus pastes the resulting information to a pertinent position of an electronic document on a display. As a result, it is possible to input information such as a character sequence, a table and a figure from a real document to an electronic document at high speed and with high accuracy.Type: GrantFiled: June 25, 2003Date of Patent: October 9, 2007Assignee: Fujitsu LimitedInventors: Koji Kurokawa, Katsuhito Fujimoto, Misako Suwa, Yoshinobu Hotta, Satoshi Naoi

Patent number: 7136526Abstract: A key word is first and automatically extracted from a character string group to be recognized, and entered. Then, a character is recognized by segmenting an individual character from a character string image to be recognized, and a character string corresponding to the extracted/entered key word id extracted. Then, a word area delimited by a key word is extracted from the character string image, and a word is recognized. Furthermore, a word recognition result is verified, and a final character string recognition result is output.Type: GrantFiled: December 18, 2001Date of Patent: November 14, 2006Assignee: Fujitsu LimitedInventors: Yoshinobu Hotta, Katsuhito Fujimoto, Satoshi Naoi, Misako Suwa

Patent number: 6535619Abstract: When a pattern of an address to be recognized is input, contact characters are separated after determining the contact position of the contact characters. A key character is extracted by recognizing characters for each of the separated characters. After extracting the key character, patterns delimited by the key character are collectively retrieved. A place-name word is recognized by comparing a feature vector of the entire pattern delimited by the key character with a feature vector of the place-name word.Type: GrantFiled: January 13, 1999Date of Patent: March 18, 2003Assignee: Fujitsu LimitedInventors: Misako Suwa, Satoshi Naoi
