    Abstract: Floating-point texture filtering units leverage existing fixed-point filter circuits. Groups of floating-point texture values are converted to products of a fixed-point mantissa and a scaling factor that is the same for each texture value in the group. The fixed-point mantissas are filtered using a fixed-point filter circuit, and the filtered mantissa is combined with the scaling factor to determine a floating-point filtered value. Multiple floating-point filter results may be combined in a floating-point accumulator circuit.

    Abstract: Many computing services incorporate large mosaics of geo-located images. For example, a user may access and interact with a digital image map comprising thousands of digital images mosaiced together. It may be advantageous to parallelize mosaic creation by splitting the mosaic into tiles, and processing the tiles independently from one another. Unfortunately, visual artifacts between image boundaries may result because of the independent processing. Accordingly, one or more systems and/or techniques for generating a substantially seamless mosaic tile are disclosed herein. A mosaic tile comprising one or more intersecting images may be received. Pair-wise image segmentation may be executed upon pairs of intersecting images within the mosaic tile to generate seam lines between the pair of intersecting images. The seam lines are used to compose the mosaic tile. A constrained alpha-expansion algorithm is executed upon hole regions within the composed mosaic to generate a substantially seamless mosaic.

  • Publication number: 20100321407
    Abstract: Visual items may each be constructed and placed in position using logic defined by a view component corresponding to each visual item, where that logic may depend on one or more values populated into parameter(s) of the view component. Some of those parameter values may correspond to known model parameter values. Others, however, may have been solved for using a model that defines analytical relationships between the model parameters. In one embodiment, which of the model parameters are known, and which are unknown, may not be predetermined. Accordingly, a solver might be prepared for multiple solve operation paths even using a single model. The view composition process may be entirely data-driven, with the solve and/or the visual items implemented using spreadsheets.

  • Patent number: 7805387
    Abstract: This invention deals with a morphological genome for design applications. This genome encodes all forms. It comprises a finite set of morphological genes, where each gene specifies a distinct group of morphological transformations defined by a group of independent topological, geometric or other parameters. The morph genes and their parameters are mapped within an integrated higher-dimensional framework with each parameter represented along an independent vector in higher-dimensional Euclidean space. Each distinct number associated with a parameter or a group of parameters is represented by a distinct point in this space referenced by its higher-dimensional Cartesian co-ordinates which represent the genetic code for the specific form being mapped. The morph genome can be used as an interactive design tool to generate known and new forms for applications in all design fields as well as for fabricating these forms when linked with digital fabrication devices within an integrated computational environment.

  • Patent number: 7800620
    Abstract: Although GPUs have been harnessed to solve non-graphics problems, these solutions are not widespread because GPUs remain difficult to program. Instead, an interpreter simplifies the task of programming a GPU by providing language constructs such as a set of data types and operations that are more familiar to non-graphics programmers. The interpreter maps these familiar language constructs to the more difficult graphics programming resources such as DirectX®, OpenGL®, Cg®, and/or HLSL®.

  • Patent number: 7796139
    Abstract: Mechanisms for displaying text or image over a background such as a video display frame that automatically improve legibility of text or image displayed against a background by increasing the contrast between text or image and background. The display frame may be a single image, but may also be an image within a dynamic sequence of recorded images such as a movie or other video media, or sequence of images captured in real-time by a camera or other device. In one embodiment, color component values are selected, and complementing and filtering applied to achieve contrast. In another embodiment, selecting a minimally used value for color components in the frame achieves contrast. In some cases both text or image, and background, may be altered to achieve contrast. Another embodiment provides background intensity modulation to achieve varying contrast within altered backgrounds, and smoothing over many frames in dynamic material.

  • Patent number: 7755649
    Abstract: Sub-pixel rendering with gamma adjustment allows the luminance for the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel, while the chrominance can match the linear response of the human eye's chrominance channels. The gamma correction allows the sub-pixel rendering to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques with gamma adjustment may be optimized for the gamma transfer curve of a display device in order to improve response time, dot inversion balance, and contrast.
