Patent number: 7937653Abstract: A method for identifying header/footer content of a document, in order to sequence text fragments comprising recognizable text blocks as derived from the document. The textual variability of lines comprised of text blocks, including the different kinds of text blocks within the line is analyzed for assessment of textual variability. Header/footer zones are defined by textual content having a low textual variability. An alternative embodiment identifies pagination constructs by comparing selected text-boxes for similarity and proximity and clustering the text boxes satisfying a predetermined similarity value, wherein the clustered text boxes are deemed to comprise pagination constructs.Type: GrantFiled: January 10, 2005Date of Patent: May 3, 2011Assignee: Xerox CorporationInventors: Hervé Déjean, Jean-Luc Meunier

Patent number: 7936925Abstract: After markings have been placed on a pre-printed form by a user who interacted with an entity, the form is scanned to produce a scan file. The scan file is analyzed to identify whether user added markings are present on machine readable selection items. The method can take a number of automated actions, depending upon which pre-printed machine readable selection items were checked by the user. For example, in response to checkbox selections, the method can obtain (read) some form of electronically storable data relating to the entity based on which of the machine readable selection items the user checked. Alternatively, in response to other checkbox selections, the method can ignore the user added markings on the machine readable selection items. In addition, in response to the checkmarks, the system can maintain only an image of the user added handwritten text.Type: GrantFiled: March 14, 2008Date of Patent: May 3, 2011Assignee: Xerox CorporationInventors: Nathaniel G. Martin, Naveen Sharma, Michael P. Kehoe, Robert St. Jacques, Jr.

Patent number: 7936914Abstract: To determine authenticity of a solid body simply and precisely, a reference area of a paper sheet which is genuine is optically read from two different directions, and the image is registered as a reference image. A check area of a paper sheet subjected to the authenticity determination, including the reference area and having a size larger than the reference area, is read from two different directions with a scanner, and data on a partial area having the same size as the reference area are extracted from each set of check data collected by the reading. For a set consisting of the reference image and the check image optically read from the same direction, the value of the correlation with the reference image is repetitively calculated by the normalized correlation method while the partial area is shifted within the check area. The maximum correlation value and the normalized score of the maximum correlation value are compared with respective thresholds to determine the authenticity of the paper sheet.Type: GrantFiled: August 10, 2005Date of Patent: May 3, 2011Assignee: Fuji Xerox Co., Ltd.Inventors: Tadashi Shimizu, Tetsuya Kimura

Patent number: 7936482Abstract: In a PC, image data, position data indicating the position of the image data, and addition data associated with the image data are created. Further, the PC requests a background management unit to send a background pattern used to specify paper and a position on the paper, and prints the background pattern together with the image data. Further, the PC registers the background pattern, the addition data, and the position data in an information server in association with each other. When the user points to an image on the paper provided as the result of printing with a handwrite input pen, the background pattern and the pointing position are detected on the paper, and the addition data corresponding to the paper and the position is output.Type: GrantFiled: September 15, 2004Date of Patent: May 3, 2011Assignee: Fuji Xerox Co., Ltd.Inventors: Naoya Takezaki, Takahiko Nomura, Yasuo Horino, Jun Kiyota, Yoichiro Maeda, Hitoshi Ihashi, Kenichi Suzuki

Patent number: 7937397Abstract: A novel method for going beyond the observed properties of a keyword, to a model in which the presence of a term in a document is assessed not by looking at the actual occurrence of that term, but by a set of non-independent supporting terms, defining the context. In other words, similarity is determined not by properties of the keyword, but by properties of the keyword's context. This yields a scoring for documents which is useful for ad hoc retrieval and, by extension, any information retrieval task where keyword-based similarity is needed.Type: GrantFiled: August 22, 2006Date of Patent: May 3, 2011Assignee: Fuji Xerox Co., Ltd.Inventor: Jeremy Pickens
