Publication number: 20100239185Abstract: A circuit arrangement, program product and method utilize the known view orientation for an image frame to be rendered to optimize the generation and/or use of an Accelerated Data Structure (ADS) used in physical rendering-based image processing. In particular, it has been found that while geometry primitives that are not within a view orientation generally cannot be culled from a scene when a physical rendering technique such as ray tracing is performed, those primitives nonetheless have a smaller impact on the resulting image frame, and as a result, less processing resources can be applied to such primitives, leaving greater processing resources available for processing those primitives that are located within the view orientation, and thereby improving overall rendering performance.Type: ApplicationFiled: March 19, 2009Publication date: September 23, 2010Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: David K.

Patent number: 7801360Abstract: The time required to execute processing for detecting the image of a face is shortened. A number of frames of the image of a subject are obtained sequentially by sensing the image of the subject successively. Face detection processing is applied to a first subject image, which is one frame of the image of the subject among the number of frames thereof. The inclination of a face-image area obtained by detection is detected. Among angles of 0°, 90°, 180° and 270°, that close to the detected inclination is decided upon. A face image having an angle within a range of 45° on either side of the decided angle as its inclination is detected from a second subject image, which is obtained following the first subject image. Since face images to undergo detection are thus restricted, detection processing ends in a comparatively short period of time.Type: GrantFiled: October 16, 2006Date of Patent: September 21, 2010Assignee: Fujifilm CorporationInventor: Daisuke Hayashi

Patent number: 7738734Abstract: In accordance with an image processing method, a data region is detected from input image data. The input image data is rotated in accordance with inclination of an image. Determination is made whether the data region of rotated image data protrudes from an image area of the input image data.

Patent number: 7680357Abstract: Voting of coordinates of each pixel in a photographic image onto a Hough space corresponding to annuluses is performed, the Hough space being defined by a coordinate system having an X coordinate axis for a circle center point, a Y coordinate axis for a circle center point, and an r coordinate axis for a radial direction. A vote value of each voting position having coordinates (X, Y, r) on the Hough space is acquired as a first integrated vote value from a calculation of a number of votes given to each voting position. A position represented by (X, Y) coordinate values of a voting position associated with the largest first integrated vote value is detected as the position of the center point of the circular pattern.Type: GrantFiled: September 8, 2004Date of Patent: March 16, 2010Assignee: Fujifilm CorporationInventors: Makoto Yonaha, Tao Chen

Patent number: 7668365Abstract: A CPU 411 splits selected image data GD into a plurality of areas (pixel data groups), analyzing the image data GD in terms of area units, and determining the color range of the areas of the image data GD. The CPU 411 determines color range areas by associating adjacent areas of the same color range when determining the color range for the areas of the image data GD. The CPU 411 acquires position data for the color range areas that have been determined. The CPU 411 acquires position conditions (main object conditions) from ROM/HDD 413, and narrows the main object candidates to “sky, green, or people.” The CPU 411 finally determines the main object by comparing the position data of the color range color areas and the position conditions corresponding to the narrowed main object.Type: GrantFiled: March 7, 2005Date of Patent: February 23, 2010Assignee: Seiko Epson CorporationInventor: Toshie Imai

Patent number: 7660451Abstract: The present invention is directed to diagnostic imaging of small pulmonary nodules. There are two main stages in the evaluation of pulmonary nodules from Computed Tomography (CT) scans: detection, in which the locations of possible nodules are identified, and characterization, in which a nodule is represented by measured features that may be used to evaluate the probability that the nodule is cancer. Currently, the most useful prediction feature is growth rate, which requires the comparison of size estimates from two CT scans recorded at different times. The present invention includes methods for detection and feature extraction for size characterization. The invention focuses the analysis of small pulmonary nodules that are less than 1 centimeter in size, but is also suitable for larger nodules as well.Type: GrantFiled: February 29, 2008Date of Patent: February 9, 2010Assignee: Cornell Research Foundation, Inc.Inventors: Anthony P. Reeves, David Yankelevitz, Claudia Henshke, Antoni Chan

Patent number: 7656425Abstract: A method characterizes field of view (FOV) distortion and may correct machine vision measurements accordingly. A plurality of distorted images are acquired, with the same calibration target at a plurality of spaced-apart locations within the FOV. The method analyzes the images and determines distortion parameters that can correct the distortions in the images such that features included in the calibration target pattern achieve a sufficient or optimum degree of congruence between the various images. Distortion parameters may be determined for each optical configuration (e.g., lens combination, magnification, etc.) that is used by a machine vision inspection system. The distortion parameters may then be used to correct FOV distortion errors in subsequent inspection and measurement operations.Type: GrantFiled: March 31, 2006Date of Patent: February 2, 2010Assignee: Mitutoyo CorporationInventors: Joseph Daniel Tobiason, Yuhua Ding

Patent number: 7653262Abstract: A video game device calculates an angle of an object 71, etc., with respect to a reference direction in a three-dimensional space. Then, the video game device defines a virtual cylindrical model for each of a plurality of objects so that a bottom surface of each cylindrical model is perpendicular to the reference direction. The video game device defines a plurality of cylindrical models for a predetermined object if the inclination of the predetermined object with respect to the reference direction is greater than a predetermined angle. Then, the video game device determines whether or not the defined cylindrical models have an overlap therebetween. Then, if two cylindrical models are determined to be overlapping with each other, the video game device gives a predetermined change to the two objects in response to the collision.Type: GrantFiled: August 4, 2006Date of Patent: January 26, 2010Assignee: Nintendo Co., Ltd.Inventors: Eiji Aonuma, Yoichi Yamada, Hajime Nakamura, Hiroshi Umemiya

Patent number: RE41364Abstract: A test image has a black bias on a white background. The black bias is a line set at about 45 degrees to the scan lines of a scanner. Boundary points of the scanned bias are found. A regression line is calculated from the positions of the boundary points. Differences in the positions of adjacent boundary points, together with the slope reciprocal of the regression line, are used to determine error values. The error values are compared with a gate value to determine if there are any occurrences of scan line misalignment.Type: GrantFiled: May 11, 2006Date of Patent: June 1, 2010Inventors: Yu-Fen Tsai, Te-Chih Chang
