  • Patent number: 8970619
    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.

  • Patent number: 8803918
    Abstract: Methods, apparatus, and computer-readable storage media for calibrating focused plenoptic camera data. A calibration technique that does not modify the image data may be applied to raw plenoptic images. Calibration parameters, including but not limited to tilt angle, corner crops, main lens distance from the microlens array, sensor distance from the microlens array, and microimage size, may be specified. Calibration may include scaling down the input texture coordinates for the plenoptic image so that the new coordinate range fits the size of the texture with crops taken into account. These coordinates may be further transformed by one or more of a matrix performing a scaling, to correct for lens distortion; a rotation, to correct for tilts; and a translation that finalizes the necessary corner crops. A transformation matrix is generated that can be applied to the raw image by radiance processing techniques such as super-resolution techniques.

  • Patent number: 8773431
    Abstract: Methods and apparatus for generating an n-sided patch by sketching on a three-dimensional reference surface. A user draws a closed curve on a 3D surface; the drawn outline is taken as a boundary for an N-sided patch. If the user does not close the curve, the system may automatically close the curve, as a closed outer boundary curve may be required to produce an N-sided patch. The boundary conditions, the positions, and the surface normals at the boundary are inferred automatically from the 3D surface that the user has drawn the curve on. In addition, boundary curves for the same patch may be drawn on different 3D shapes; multiple 3D shapes may be used as the template or canvas on which the user draws curves from which a patch is to be generated.

  • Patent number: 8760462
    Abstract: The present invention relates to a unique color management method for calibrating and characterizing a light mixing system comprising a set of primary light modules emitting self-luminous color primaries, which may be intimately mixed to produce a batch color that matches a standard color. The radiant output of each self-luminous color primary, or channel, is modulated by a setting a light controller to a Digital-to-Analog-Conversion (“DAC”) value. In the event that the radiant output of the color primary channels is non-linearly proportioned to the DAC input values, it is useful to employ an innovative “iterative best-fit” method of simultaneously calculating admixtures of light from all color primaries that match a standard color. Otherwise, a matrix method based on matrix algebra may also be used to create a batch color that matches a standard color. A best fit tristimulus value method or best fit minimum RMSD can be used in conjunction with these spectral color matching methods.

    Abstract: A method, computer program product, and computer system for identifying a first reference point on a display. A second reference point of an object of an application is identified, wherein the object is on the display. A distance is determined of the first reference point on the display from the second reference point of the object on the display. One or more properties of the application is adjusted based upon, at least in part, the distance of the first reference point on the display from the second reference point of the object on the display.

  • Patent number: 8633942
    Abstract: Images provide rich information regarding what they depict. For example, an image may have additional information, such as depth and/or 3D location values, for some points within the image. It may be advantageous to extrapolate the values from the valued points to the entire image because a new view of the image may be generated based upon values of points. Accordingly, an interpolated image may be generated by interpolating values for unvalued points based upon values of valued points. In particular, a set of valued points having desired cost paths may be determined for an unvalued point. A model may be applied to the set of valued points to interpolate a value for the unvalued point. One or more interpolated images may be projected onto a new view. In particular, points within an interpolated image may be projected onto locations within the new view based upon values of the points.
