| 20110037831 | METHOD FOR DETERMINING A THREE-DIMENSIONAL REPRESENTATION OF AN OBJECT USING POINTS, AND CORRESPONDING COMPUTER PROGRAM AND IMAGING SYSTEM - The method of the invention includes: determining a set of points of a space and a value of each of these points at a given moment, the set of points including the points of the object in the position thereof at the given moment; selecting a three-dimensional representation function that can be parameterized with parameters and an operation that gives, using the three-dimensional representation function, a function for estimating the value of each point in the space; and determining parameters, such that, for each point in the set, the estimation of the value of the point substantially gives the value of the point. | 02-17-2011 |
| 20110064271 | METHOD FOR DETERMINING A THREE-DIMENSIONAL REPRESENTATION OF AN OBJECT USING A SEQUENCE OF CROSS-SECTION IMAGES, COMPUTER PROGRAM PRODUCT, AND CORRESPONDING METHOD FOR ANALYZING AN OBJECT AND IMAGING SYSTEM - The method comprises, for each cross-section image, determining the position of the object (O) in relation to the cross-section plane at the moment the cross-section image is captured, and determining a three-dimensional representation (V) of the object (O) using cross-section images (X | 03-17-2011 |

| 20080240540 | APPEARANCE MANIFOLDS FOR MODELING TIME-VARIANT APPEARANCE OF MATERIALS - A method for modeling a time-variant appearance of a material is described. A sample analysis of a material sample is performed, wherein the sample analysis orders surface points of the material sample with respect to weathering from data captured at a single instant in time. An appearance synthesis using the sample analysis is performed, wherein the appearance synthesis generates a time-variant sequence of frames for weathering an object. | 10-02-2008 |
| 20090219287 | Modeling and rendering of heterogeneous translucent materials using the diffusion equation - An exemplary method includes providing image data for an illuminated physical sample of a heterogeneous translucent material, determining one or more material properties of the material based in part on a diffusion equation where one of the material properties is a diffusion coefficient for diffusion of radiation in the material and where the determining includes a regularization term for the diffusion coefficient, mapping the one or more material properties to a virtual object volume, assigning virtual illumination conditions to the virtual object volume, and rendering the virtual object volume using the virtual illumination conditions as a boundary condition for a system of diffusion equations of the virtual object volume. Other methods, devices and systems are also disclosed. | 09-03-2009 |
| 20100277477 | Modeling Anisotropic Surface Reflectance with Microfacet Synthesis - Described is a search technology in which spatially varying anisotropic reflectance is modeled using image data captured from a single view. Reflectance at each point is represented using a microfacet-based Bidirectional Reflectance Distribution Function (BRDF). Modeling processes the image data, which provides a partial normal distribution function (NDF) for each surface point. The NDF at each selected point is completed by texture synthesis using similar, overlapping partial NDFs from other points. Also described is a scanning device that illuminates a sample surface from a two-dimensional set of light directions using a linear array of LEDs moved over a flat sample. | 11-04-2010 |
| 20110157192 | Parallel Block Compression With a GPU - Disclosed is a system and method for determining, in parallel on a graphics processing unit, a block compression case which results in a least error to a block. Once determined, the block compression case may be used to compress the block. | 06-30-2011 |
