Patent number: 8150161Abstract: Embodiments of a computer system, a method, and a computer-program product (e.g., software) for use with the computer system are described. These embodiments may be used to identify and correct errors in financial information that was extracted using character-recognition software, such as optical character recognition software and/or intelligent character recognition software. In particular, potential errors may be identified by comparing the financial information for a current financial transaction of a user with expected financial information from one or more previous financial transactions of the user. Error metrics for these potential errors may be determined and used to correct at least some of the potential errors. For example, values of the Levenshtein edit distance may be determined based on the comparison, and one or more potential errors associated with one or more minimum values of the Levenshtein edit distance may be corrected.Type: GrantFiled: September 22, 2008Date of Patent: April 3, 2012Inventors: William T. Laaser, Rajalakshmi Ganesan, James A. Schneider

Patent number: 8131085Abstract: Techniques for shape clustering and applications in processing various documents, including an output of an optical character recognition (OCR) process. The output of an OCR process is classified into a plurality of clusters of clip images and a representative image for each cluster is generated to identify clusters whose clip images were incorrectly assigned character codes by the OCR process.Type: GrantFiled: July 15, 2011Date of Patent: March 6, 2012Assignee: Google Inc.Inventors: Luc Vincent, Raymond W. Smith

Patent number: 8103132Abstract: A method for correcting results of OCR or other scanned symbols. Initially scanning and performing OCR classification on a document. Clustering character/symbol classifications resulting from the OCR based on shapes. Creating super-symbols based on at least a first difference in the shapes of the clustered characters/symbols exceeding a first threshold. A carpet of super-symbols, emphasizing localized differences in similar symbols, is displayed for analysis testing.Type: GrantFiled: March 31, 2008Date of Patent: January 24, 2012Assignee: International Business Machines CorporationInventors: Asaf Tzadok, Eugeniusz Walach

Patent number: 7912289Abstract: Image text enhancement techniques are described. In an implementation, graphically represented text included in an original image is converted into process capable text. The process capable text may be used to generate a text image which may replace the original text to enhance the image. In further implementations the process capable text may be translated from a first language to a second language for inclusion in the enhanced image.Type: GrantFiled: May 1, 2007Date of Patent: March 22, 2011Assignee: Microsoft CorporationInventors: Aman Kansal, Feng Zhao

Patent number: 7849398Abstract: A method is provided for selecting fields of an electronic form for automatic population with candidate text segments. The candidate text segments can be obtained by capturing an image of a document, applying optical character recognition to the captured image to identify textual content, and tagging candidate text segments in the textual content for fields of the form. The method includes, for each of a plurality of fields of the form, computing a field exclusion function based on at least one parameter selected from a text length parameter, an optical character recognition error rate, a tagging error rate, and a field relevance parameter; and determining whether to select the field for automatic population based on the computed field exclusion function.Type: GrantFiled: April 26, 2007Date of Patent: December 7, 2010Assignee: Xerox CorporationInventors: Sebastien Dabet, Marco Bressan, Hervé Poirier

Patent number: 7813576Abstract: A difference image is obtained between two images which are objects of comparative viewing, regardless of whether the images are processed images. A judgment means judges whether the two images are processed images, based on process confirmation data attached thereto. A correction means corrects images which have been judged to be processed images by the judgment means to a state equivalent to that of the images prior to image processes. The correction is performed based on image processing condition data which are attached to the processed images. A positional alignment means aligns the positions of the two images. An inter image calculation means performs inter image calculation between unprocessed or corrected images.Type: GrantFiled: November 24, 2003Date of Patent: October 12, 2010Assignee: FUJIFILM CorporationInventor: Akira Oosawa

Patent number: 7729541Abstract: A method is provided for converting a two-dimensional image or bitmap of a handwritten manuscript into three-dimensional data The three-dimensional data can be used to automatically recognize features of the manuscript, such as characters or words. The method includes the steps of: converting the two-dimensional image into three-dimensional volumetric data; filtering the three-dimensional volumetric data; and processing the filtered three-dimensional volumetric data to resolve features of the two-dimensional image. The method can be used, for example, to differentiate between ascenders, descenders, loops, curls, and endpoints that define the overall letter forms in handwritten text, manuscripts or signatures.Type: GrantFiled: March 16, 2005Date of Patent: June 1, 2010Assignee: Arizona Board of Regents, A Body Corporate, Acting for and on Behalf of Arizona State UniversityInventors: Anshuman Razdan, John Femiani
