Patent number: 8326041Abstract: Data on a document is recognized using at least two machine recognition processes. Data from one machine recognition process is used as reference data; data formed using the other recognition process is used as verification data. If the verification data matches the reference data, machine recognition may be verified. If the verification data does not exactly match the reference data, an assessment is made of the likelihood that the verification data is sufficiently close to the reference data to suggest an error in the verification data. This may be done by applying a fitness function to the verification data, to assess the likelihood that the verification data represents a mis-recognized version of the reference data. In one embodiment, the verification data is OCR data, and the reference data is MICR data.Type: GrantFiled: May 11, 2007Date of Patent: December 4, 2012Inventor: John Wall

Patent number: 8321222Abstract: A speech synthesis system and method is described. A speech segment database references speech segments having various different speech representational structures. A speech segment selector selects from the speech segment database a sequence of speech segment candidates corresponding to a target text. A speech segment sequencer generates from the speech segment candidates sequenced speech segments corresponding to the target text. A speech segment synthesizer combines the selected sequenced speech segments to produce a synthesized speech signal output corresponding to the target text.Type: GrantFiled: August 14, 2007Date of Patent: November 27, 2012Assignee: Nuance Communications, Inc.Inventors: Vincent Pollet, Andrew Breen

Patent number: 8315482Abstract: Described is a technology that provides an integrated platform for users to use different kinds of digital ink (e.g., handwritten characters, sketched shapes, handwritten formulas) when interacting with computer programs. The platform interprets the user's digital ink input and outputs one or more associated items into an application program. The output items can be customized for different application programs. In one aspect, the platform includes an ink panel having different operating modes for receiving digital ink, and a recognition service that recognizes different types of digital ink. The recognition service may include a unified recognizer that recognizes different types of digital ink, e.g., characters and shapes. Another recognizer may be included such as an equation recognizer. If the recognition result is text while in a non-text mode, the text may be used in a keyword search to locate items; otherwise, the recognition result may be used without keyword searching.Type: GrantFiled: June 26, 2007Date of Patent: November 20, 2012Assignee: Microsoft CorporationInventors: Xiaohui Hou, Yingjun Qiu, Dongmei Zhang, Jian Wang

Patent number: 8306330Abstract: A method to detect answers and notes inputted a game apparatus including: receiving user input data and determining the received user input data to be an answer character based on a characteristic of the user input data; displaying on the display the answer character contemporaneously with the determination of the received user data is the answer character; making a game determination based on the answer character; displaying a result of the game determination; determining the received user input data to be a note character based on the characteristic of the user input data; displaying the note character contemporaneously with the determination that the user input data is the note character; settling the note character as an answer character based on a user input made after the note character is displayed, and displaying the answer character determined from settling the note character.Type: GrantFiled: March 10, 2011Date of Patent: November 6, 2012Assignee: Nintendo Co., Ltd.Inventors: Koichi Kawamoto, Jun Ito

Patent number: 8306329Abstract: A language-neutral method for searching online handwritten notes is provided. The different algorithms contained in this method enable querying online multilingual handwritten documents with substrings of words rather than just whole words. More particularly, two approaches are presented —one based on partial Fréchet distance calculations and the other based on a pair hidden Markov models. The partial Fréchet distance is adapted from the traditional Fréchet distance concept to match a subcurve or prefix of a query word. The pair hidden Markov model used in the present application is adapted from pair hidden Markov models used in bioinformatics as generative models of local and global alignment of biological sequences.Type: GrantFiled: November 13, 2009Date of Patent: November 6, 2012Assignee: Indian Institute of ScienceInventors: Chiranjib Bhattacharyya, Sriraghavendra Ramaswamy

Patent number: 8306327Abstract: A method and system for recognizing a character affected by a noise or an obstruction is disclosed. After receiving an image with characters, a character being affected by a noise or an obstruction is determined. Then, areas in the character where the noise or obstruction affected are precisely located. Templates representing every possible character in the image are updated by removing equivalent areas to the areas in the character being affected by the noise or obstruction. Then, the character is classified in a template among the updated templates by finding the template having the highest number of matching pixels with the character.Type: GrantFiled: December 30, 2008Date of Patent: November 6, 2012Assignee: International Business Machines CorporationInventors: Ami Ben-Horesh, Amir Geva, Eugeniusz Walach

Patent number: 8306328Abstract: A method converts an outline character to a stylized stroke character by first identifying regions of the outline character, wherein each region is closed and disjoint. For each region, candidate locations for stroke bodies and terminals of the stylized stroke character are determined. The stroke bodies are then initialized and organized into a hierarchical tree stricture, and modified in an order of the hierarchical tree structure. End positions of the modified stroke bodies are then adjusted to match the outline character, and lastly, the terminals are selected for the adjusted stroke bodies.Type: GrantFiled: January 26, 2009Date of Patent: November 6, 2012Assignee: Mitsubishi Electric Research LaboratoriesInventors: Elena J. Jakubiak, Ronald N. Perry, Sarah F. Frisken

Patent number: RE43813Abstract: An image processing apparatus includes an image reader for reading an image. A display controller displays the read image on a display device. A determination unit receives an area specified by an operation performed on the image displayed on the display device so as to determine a processing area to be subjected to predetermined image processing. A setting unit sets an operation area for providing an instruction to execute the predetermined image processing on the processing area determined by the determination unit, the operation area being based on an end point of the area specified by the operation.Type: GrantFiled: August 24, 2011Date of Patent: November 20, 2012Assignee: Canon Kabushiki KaishaInventor: Yasushi Mochizuki
