Patent number: 9870520Abstract: The disclosed embodiments relate to a system and method for calibrating optical character recognition (OCR) processes for an image captured through a mobile computing device. During operation, the system adjusts the OCR process through pre-recognition functions, OCR functions and/or post-recognition functions with multiple sets of parameter settings. With each of these sets, the system scores the OCR process output against an image with known text. Once the sets are scored, the system sorts the sets of parameters, removes some sets, then mixes and mutates the remaining sets in a process akin to evolutionary biology. By repeating this procedure, the system produces a set of parameter settings that can be used to calibrate OCR processing.Type: GrantFiled: August 2, 2013Date of Patent: January 16, 2018Assignee: INTUIT INC.Inventors: Richard J.

The first generation unit generates data of a first target object obtained by using an image capture unit attached above a reading platen to read the first target object placed in a reading area of the reading platen. The determination unit determines, in a state where the first target object is placed in the reading area, whether a second target object has been placed in the reading area. The second generation unit generates data of a second target object obtained by using the image capture unit to read the second target object. The association unit associates, in response to determining that the second target object has been placed in the reading area, the data of the first target object with the data of the second target object.Type: GrantFiled: May 30, 2013Date of Patent: August 4, 2015Assignee: Canon Kabushiki KaishaInventor: Yasuo Okutani

Patent number: 9082199Abstract: A video processing device has an input for receiving video data, at least one processing circuit, for generating processed video data from the received video data, and a memory, for receiving the processed video data. An output circuit reads the processed video data from the memory, and generates frames of data including at least the processed video data. In order to be able to operate with an output clock frequency that may differ from the ideal output clock frequency, it is possible to vary the frame size, that is, the number of pixels of data in a frame. If an amount of processed video data stored in the memory exceeds an upper threshold, then the frame size can be reduced by reducing the number of pixels of blanking data in the output frame, thereby increasing the rate at which data is read from the memory.Type: GrantFiled: May 24, 2006Date of Patent: July 14, 2015Assignee: Altera CorporationInventors: Andrew Crosland, Roger May

Patent number: 9041689Abstract: A computing device and/or application executing on the device can utilize fingertip tracking using a camera. However, when the fingertip is in a dead zone (an area that is not viewable by the camera), the fingertip tracking cannot function properly. Nevertheless, the position of the fingertip, when in the dead zone, can still be estimated. An image of a user's hand can be captured by at least one camera. A portion of a pointing finger can be detected in the captured image. An orientation of the portion of the pointing finger can be determined. One or more joint lines of the pointing finger can be identified. Based on data about a slant and/or a bend of the pointing finger obtained using information relating to the identified joint line(s), and/or on data obtained via calibration and/or historic/current usage, the position of the fingertip, when in the dead zone, can be approximated.Type: GrantFiled: August 2, 2012Date of Patent: May 26, 2015Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Dong Zhou, Isaac S.

Patent number: 9036883Abstract: A noninvasive, quantitative imaging technique is presented for detecting and diagnosing liver disease, such as cirrhosis. The technique includes: capturing scan data from a subject using computed tomography or another type of imaging method and extracting image data representing the liver from the scan data. Various measures of the liver may be obtained from image data and then used to compute random variables of a statistical model, where the model is predictive of a medical condition of the liver and comprised of random variables that are indicative of at least one of a shape or texture of the liver. Output from the statistical model provides an indication of an undesirable condition of the liver.Type: GrantFiled: January 9, 2012Date of Patent: May 19, 2015Assignee: The Regents of The University of MichiganInventors: Grace L. Su, Stewart Wang, Hannu Huhdanpaa

System for determining individual user anthropometric characteristics related to mattress preference
Patent number: 9033901Abstract: A measuring device to aid mattress selection has an upstanding frame with a plurality of vertically space-apart horizontal illuminated strips. A camera mounted in front of the frame takes front view and side view images of a person standing in front of the illuminated strips. These images are delivered to an associated computer having means to determine the body mass distribution and the spine curvature of the person based on the images of the strips taken by the camera and in particular based on those portions of the image of the illuminated strips blocked by the person standing in front of the illuminated strips. This information can then be used to aid in appropriate mattress selection for the person.Type: GrantFiled: September 20, 2010Date of Patent: May 19, 2015Inventors: David Woolfson, Duncan Bain, Lee Hubbard -
Publication number: 20150131914Abstract: This shape data generation method include: setting an input shape that has a simple shape that has a same topology as the target shape for a target shape that is a shape of a transformation target identified from image data; identifying first vertices that satisfy a predetermined condition including a first condition that a normal line of a certain vertex of the plural vertices crosses with the target shape, among plural vertices of the input shape; transforming the input shape so that a first vertex is moved in a direction of a normal line of the first vertex by a first distance that is shorter than a distance up to the target shape; and performing the identifying and the transforming a predetermined number of times while changing the input shape after the transforming as the input shape to be processed.Type: ApplicationFiled: January 23, 2015Publication date: May 14, 2015Applicants: Fujitsu Limited, The University of TokyoInventors: Machiko NAKAGAWA, Kohei HATANAKA, Toshiaki HISADA, Seiryo SUGIURA, Takumi WASHIO, Jun-ichi OKADA

Publication number: 20150131913Abstract: Interactive drawing recognition is described using status determination. In one example, a computer system status is determined and then used to determine a type of drawing. A user drawing is observed and a library of drawing templates associated with the determined drawing type is accessed. The observed drawing is compared to the drawing templates to identify the observed drawing, and attributes are assigned to the identified drawing.Type: ApplicationFiled: December 30, 2011Publication date: May 14, 2015Inventors: Glen J.

Publication number: 20150125083Abstract: Techniques for object detection are provided that employ limited learned attribute ranges. One or more objects are initially detected for a full range of one or more attributes at each location of an image. Thereafter, a set of positional constraints are generated indicating an expected range of values for each position in the image for one or more of the attributes based on the detected objects employing a geometric model of a scene in the image. Objects are then detected in the image using the expected range of values for each position in the image for the one or more the attributes. The attributes comprise, for example, one or more of size, pose and rotation of the objects. A best fit is computed to the geometric model to generate the set of positional constraints, for example, using a least squares approach.Type: ApplicationFiled: November 6, 2013Publication date: May 7, 2015Applicant: International Business Machines CorporationInventors: Lisa M.
