Abstract: Attributes associated with components of a three-dimensional source geometry may be transferred to a target geometries having an arbitrarily different topology. The two geometries are placed in a general alignment in three dimensions. Correspondences are found between anchors for attributes in the target geometry and anchors for attributes in the source geometry. The identified correspondence locations on the source geometry are locally redistributed so as to ensure that concave regions of the source geometry are mapped to the target geometry, and that convex edges or vertices of the source geometry do not map to a large area on the target geometry. Attribute discontinuities in the source geometry are preserved in the target geometry by relating discontinuous edges in the source geometry to the target geometry. This relationship may map each discontinuous edge in the source geometry locally to the target geometry.

Abstract: An anisometric texture synthesis system and method for generating anisometric textures having a similar visual appearance as a given exemplar, but with varying orientation and scale. This variation is achieved by modifying the upsampling and correaction processes of the texture synthesis technique using a Jacobian field. The modified correaction process includes accessing only immediate neighbors of a pixel instead of non-local pixels. This constraint that only immediate neighbors be used also allows the generation of seamless anisometric surface textures. This is achieved by using indireaction maps containing indirection pointers that are used to jump from a set of pixels outside the boundary of a texture atlas chart to another chart. The system and method also includes an anisometric synthesis magnification technique that uses a Jacobian field to modify the magnification step of a synthesis magnification scheme and account for anisometry.

Abstract: According to an embodiment of the present invention, selective tristimulus corrections to device-independent coordinates are applied using a piecewise linear correction function. The piecewise linear correction function is defined such that a maximum of the piecewise linear correction function occurs at a boundary condition of a corresponding device-dependent color space, and the piecewise linear correction function is linearly reduced to zero or approximately zero as values in the corresponding device-dependent color space approach either a different boundary condition or a neutral axis. By having the piecewise linear correction function reduce linearly to zero or approximately zero, corrections to one region of color smoothly diminish and blend into the other regions of color, thereby substantially preventing the introduction of artifacts or image corruption due to the corrections.

Abstract: A display system includes a subpixelated display panel having subpixels in two saturated primary colors. In one embodiment, the primary colors are selected so as to be a substantially metameric pair for an achromatic color such as white. Information display efficiencies arise from utilizing a checkerboard arrangement for the two primary colored subpixels and from using subpixel rendering algorithms to render an image on the display. The bichromatic display may display a black and white image combined with a monochromatic image, or may provide the capability to overlay a first image from a first image source carried on a chromatic channel onto a second image from a second image source carried on a luminance channel, where the first image source detects light wavelengths that the Human Vision System is not sensitive to, such as infrared light. This latter embodiment of the bichromatic display system is suitable for night vision devices.

Abstract: A computer implemented image editing tool and method for using the tool for color-selective editing of a digital image including multiple shapes with different color fills displayed on a display. The image editing tool includes a modified group color mixer which has a plurality of markers representing the colors of the plurality of shapes in the digital image. By dragging the markers, multiple shapes can be edited with the same group color mixer. The image editing tool also includes a color organizer which has swatches corresponding to the number of shapes and the color fills of shapes in the digital image. The swatches are positioned according to the positions of the corresponding shapes in the digital image for easy identification. Users can drag and drop swatches to swap colors between shapes, add new colors, discard colors, store colors for reference, edit multiple swatches simultaneously, and organize colors.

Abstract: A method and apparatus for performing multisampling-based antialiasing in a system that includes first and second graphics processing unit (GPUs) that reduces the amount of data transferred between the GPUs and improves the efficiency with which such data is transferred. The first GPU renders a first version of a frame using a first multisampling pattern and the second GPU renders a second version of a frame in the second GPU using a second multisampling pattern. The second GPU identifies non-edge pixels in the second version of the frame. The pixels in the first version of the frame are then combined with only those pixels in the second version of the frame that have not been identified as non-edge pixels to generate a combined frame.

Abstract: One embodiment of the present invention provides a system for making a color adjustment to a digital image. The system displays a digital image in a user interface. Upon receiving an adjustment to a gain control, the system adjusts a magnitude of a color adjustment made to a digital image when a user moves an adjustment indicator within a two-dimensional region that displays a spectrum of possible adjustments for the color of the digital image. Upon receiving a color adjustment from the adjustment indicator, the system adjusts the color of the digital image based on the color adjustment.
