  • Publication number: 20170017741
    Abstract: A computational engineering modelling tool having a point generation module arranged to read geometry data representing a domain to be modelled. The point generation module also generates point data for the domain having multiple boundary points located on a boundary of the domain and multiple further points spaced from the boundary within the domain. A point mutation module processes the point generation module output and generates automatically a plurality of alternative point data definitions for the domain in which the location of at least one point differs between each of the alternative point definitions. A blocking module discretizes the domain by creating multiple geometric blocks over the domain using a computational geometric operator wherein each point represents a vertex of at least one block. The blocking module outputs a discretized computational model of the domain and the tool scores the model according to a geometric attribute of the blocks.

  • Patent number: 9508140
    Abstract: A method and system are proposed to obtain quantitative data about the shape of a biological structure, and especially a heart ventricle. A set of three-dimensional input meshes are generated from MRI data. They represent the shape of a ventricle at successive times. The input meshes are used to generate a set of three-dimensional morphed meshes which have the same number of vertices as each other, and have respective shapes which are the shapes of corresponding ones of the input meshes. Then, for each of the times, shape analysis is performed to obtain a curvedness value at each of a plurality of corresponding locations in the morphed meshes. The curvedness value may be used to obtain a curvedness rate at each of the locations, indicative of the rate of change of curvedness with time at each of the locations.

  • Publication number: 20160227209
    Abstract: An image sensor of a camera configured with a diffraction grating is used to capture a diffraction image of an image rendering surface of a display device, for example, while a target image is being rendered on the image rendering surface of the display device. The diffraction image of the image rendering surface of the display device is analyzed to obtain measurements of native display capabilities of the display device. Display capability data is transmitted to a display management module for the display device. At least a portion of the display capability data is generated from the measurements of native display capabilities of the display device that are obtained from analyzing the diffraction image of the image rendering surface of the display device.

  • Patent number: 9299167
    Abstract: Methods and apparatus are provided for encoding and decoding image data using localized gamut definitions. The localized gamut definitions may be defined based on gamut characteristics of the image data. A gamut transform is applied to the image data wherein color coordinates specified by the image data are mapped to corresponding color coordinates in the localized gamut definition. Use of localized gamut definitions may facilitate image data compression of increased color depth specification of image data.

  • Publication number: 20150287368
    Abstract: Techniques for driving a dual modulation display include generating backlight drive signals to drive individually-controllable illumination sources. The illumination sources emit first light onto a light conversion layer. The light conversion layer converts the first light into second light. The light conversion layer can include quantum dots or phosphor materials. Modulation drive signals are generated to determine transmission of the second light through individual subpixels of the display. These modulation drive signals can be adjusted based on one or more light field simulations. The light field simulations can include: (i) a color shift for a pixel based on a point spread function of the illumination sources; (ii) binning difference of individual illumination sources; (iii) temperature dependence of display components on performance; or (iv) combinations thereof.

  • Patent number: 9031356
    Abstract: Perceptually correct noises simulating a variety of noise patterns or textures may be applied to stereo image pairs each of which comprises a left eye (LE) image and a right eye (RE) image that represent a 3D image. LE and RE images may or may not be noise removed. Depth information of pixels in the LE and RE images may be computed from, or received with, the LE and RE images. Desired noise patterns are modulated onto the 3D image or scene so that the desired noise patterns are perceived to be part of 3D objects or image details, taking into account where the 3D objects or image details are on a z-axis perpendicular to an image rendering screen on which the LE and RE images are rendered.

  • Patent number: 8963947
    Abstract: Approximation errors commonly occur when color transformation values stored in color look-up tables are interpolated to produce color display drive signals, since the stored transformation values typically correspond to non-linear functions. Such errors can be reduced by applying a pre-indexing function to the transformation values before they are stored in the look-up table, and by applying the same function to values extracted from the table during look-up operations. Alternatively, such errors can be reduced by providing one or more additional look-up tables to achieve higher order (i.e. more accurate) interpolation results that are achievable by interpolation of values stored in a single look-up table.
