The method of this invention comprises the steps of applying a dynamic range reducing filter to the digitized image values, obtaining a range reduced image; applying an edge detecting filter to the range reduced image, obtaining a filtered image; and then, adaptively binarizing the digitized image utilizing the corresponding filtered image to obtain an adaptive threshold.Type: GrantFiled: March 22, 2002Date of Patent: June 26, 2007Assignee: Lockheed Martin CorporationInventors: Lawrence E. Albertelli, David L. Ii, Nina Kung

Patent number: 7236170Abstract: Deformations are applied to a model using a subdivision surface. Given a wrap and model, a subdivision surface is calculated from the wrap. The model is then bound to the subdivision surface. When the wrap is deformed, the subdivision surface is recalculated. The model is then deformed based on changes in the subdivision surface. Binding parameters may be assigned to control vertices in the wrap to control the application of the deformation to the surface.Type: GrantFiled: January 29, 2004Date of Patent: June 26, 2007Assignee: DreamWorks LLCInventor: Miguel A. Sepulveda

Patent number: 7233340Abstract: Computerized techniques are provided for linking digitized images of serial sections of a biological tissue sample. Linked, digitized images of the serial section are displayed on a display and manipulation of one digitized image causes other digitized images to be similarly manipulated. To link digitized images, a copy of a digitized image of one serial section is positioned over a digitized image of another serial section. The digitized image of the other serial section is visible through the copy. The copy is registered to the digitized image of the other serial section.Type: GrantFiled: April 30, 2003Date of Patent: June 19, 2007Assignee: Applied Imaging Corp.Inventors: William Hughes, Duncan William Borthwick

Patent number: 7227545Abstract: A method, computer readable storage, and apparatus for improving subdivision schemes for subdivision surfaces. The present method can correct distortion from the base mesh caused by prior art subdivision and smoothing schemes. In one embodiment, the method includes: (a) subdividing a curve having original vertices producing additional vertices; (b) smoothing the curve into smoothed vertices comprising smoothed original vertices and smoothed additional vertices; and (c) adjusting positions of the smoothed vertices.Type: GrantFiled: May 24, 2002Date of Patent: June 5, 2007Assignee: Autodesk, Inc.Inventors: Jerome Maillot, Jos Stam

Patent number: 7201482Abstract: A projection type display device includes a distortion corrector for correcting a projected image for distortions when the image is projected with a projection optical axis tilted with respect to a screen. The distortion corrector comprises a tilt angle generator for finding a tilt angle of the projection optical axis, and a display image corrector for correcting the display image using the tilt angle. The display image corrector comprises a two-dimensional table for storing corrected coordinates for four vertexes of the display image employing a vertical tilt angle and a horizontal tilt angle as variables, and a fixed point determiner for selecting one of the four vertexes as a fixed point.Type: GrantFiled: August 23, 2004Date of Patent: April 10, 2007Assignee: NEC Viewtechnology, Ltd.Inventor: Youichi Tamura

Patent number: 7173633Abstract: In a data processing system that executes a program of instructions, a method of inverting a distorted surface in a detail-in-context presentation is provided comprising the steps of locating a first approximation point in an undistorted surface for the inversion of a point in a distorted surface, determining if the approximation point is acceptable as an inversion of the point in the distorted surface, locating a next approximation point in the undistorted surface if the first approximation point is not acceptable, and repeating this process until an acceptable approximation point is located for the inversion of the point in the distorted surface. The use of this method to obtain the distance between points on an undistorted surface from the relative distances between corresponding points on a plurality of distorted surfaces in a detail-in-context presentation is provided.Type: GrantFiled: March 1, 2004Date of Patent: February 6, 2007Assignee: Idelix Software Inc.Inventor: Mark H. A. Tigges

Patent number: 7161606Abstract: Apparatuses and methods are presented that use a direct synthesis approach using layers in order to directly generate a virtual view from a pair of images. In one embodiment, a range space is discretized into a plurality of layers. For each layer, the first input image and the second input image are warped to the layer. A matching score is then determined for each pixel in the new view based on the warped input images. For each pixel in the virtual view, a best layer is determined. After the best layer has been determined, the color of the pixel in that layer is used for that pixel in the generated view.Type: GrantFiled: September 8, 2004Date of Patent: January 9, 2007Assignees: Honda Motor Co., Ltd., The Regents of the University of CaliforniaInventors: Héctor H.

Patent number: 7156524Abstract: A microcomputer performs image drawing processing of a projection video for adjustment by an OSD (On-Screen Display) circuit when it detects the press of an adjustment command key. The projection video for adjustment is an image having a black-and-white area high in contrast formed therein. The projection video for adjustment is picked up by a CCD line sensor in a sensor. A microcomputer has its input an image pick-up signal from the CCD line sensor, to make focusing adjustment and trapezoidal distortion correction on the basis of the image pick-up signal.Type: GrantFiled: July 15, 2004Date of Patent: January 2, 2007Assignee: Sanyo Electric Co., Ltd.Inventors: Yoshichika Hirao, Naoki Kaise, Kenji Hyakutake
