Abstract: One embodiment of the present invention sets forth a method for accessing display configuration information of a display device in a multi-graphics-processing-unit (multi-GPU) system based on a hot-plug detection signal associated with the same display device. The method includes the steps of changing the power state of a discrete GPU (dGPU) in the multi-GPU coupled to the display device after having detected an assertion of the hot-plug detection signal, retrieving the display configuration information of the display device with the dGPU, and powering down the dGPU after having retrieved the display configuration information.

Abstract: In one example, images may be used to create a model of a three-dimensional space, and the three-dimensional space may be annotated and/or edited. When a three-dimensional model of a space has been created, a user may associate various items with points in the three-dimensional space. For example, the user may create a note or a hyperlink, and may associate the note or hyperlink with a specific point in the space. Additionally, a user may experiment with the space by adding images to, or deleting images from, the space. Annotating and editing the space, rather than the underlying images, allows annotations and edits to be associated with the underlying objects depicted in the images, rather than with the images themselves.

Abstract: New views of a 2D image are generated by identifying an object class within the image, such as through a face detector. The face is then fitted to a model face by means of an AAM, and the results extended to a fitted 3D polygon mesh face. A boundary perimeter with predefined anchor points and a predefined triangulation with the 3D polygon mesh is defined a predefined depth distance from the depth center of known landmarks within the 3D polygon mesh face. By rotating the 3D polygon mesh face relative to the boundary perimeter, which may follow the perimeter of the input image, new views of the input image are generated.

Abstract: The present disclosure includes systems and techniques relating to identifying function samples for use in interpolation. In general, in one implementation, the technique includes: obtaining a set of unevenly spaced sample points, x, and corresponding sample outputs, y, of a function y=f(x) within a domain; generating a data structure including first locations corresponding to a set of evenly spaced sample points within the domain, wherein the first locations store index values corresponding to second locations storing the sample outputs, y; receiving an input value of image data; identifying one of the first locations corresponding to the input value; finding two index values stored in the first locations using the one of the first locations as a starting point; and generating an image data output value corresponding to the input value by interpolation using two sample outputs, y, obtained from the second locations using the two index values.

Abstract: Effectively displaying the results of a search, or identifying a specific object in a collection when the user only has a vague recollection of the properties of the object or is uncertain of the best search terms to use, is a difficult problem. To address such difficulties a method for displaying a collection of objects in three dimensions (3D) is described. Each object is represented using an image or icon and has associated metadata. Common metadata attributes such as colour (RGB, Brightness), creation date, title etc, between the objects are used to define a data space and each object is assigned a point in the dataspace. The dataspace is then projected down to a 3D viewing space where a representation or image of the object will be displayed in. To improve the visualisation of the objects, the projected points are adjusted so as to reduce the clustering of points whilst maintaining or preserving the order of the points.

Abstract: A method is provided in one example and includes receiving a video input from a video source coupled to a display configured for rendering a user interface thereon; evaluating a plurality of pixels within the video input; and determining if a particular pixel within the pixels is associated with a color that matches a designated value associated with a chroma-key. If a match is found for the particular pixel, then the particular pixel is rendered as a clear image on the display, and if the match is not found, the particular pixel is darkened by a certain percentage.

A list of critical features with respect to the document can be selected and previewed by a user via a set of media controls displayed at the user interface.

Abstract: Conversion between z-scanning indices, raster-scanning indices and two-dimensional coordinates uses simple bit-operations in high efficiency video coding. Depending on the conversion, certain bits are extracted from one representation to obtain positions of another representation, or bits are interleaved to generate another representation. Conversion is able to be between any of z-scanning indices, raster-scanning indices and (x,y) representations.

Abstract: An authoring tool assigns a first depth value to a first image layer and a second depth value to a second image layer. The first depth value is a first simulated distance from a user. The second depth value is a second simulated distance from the user. The authoring tool composes an image based on the first image layer and the second image layer such that the image is displayed within a page in a scrollable area on a viewing device. The first depth value is utilized to generate a first offset value from a first static position of the first image layer and the second depth value is utilized to generate a second offset value from a second static position of the second image layer based upon a scroll position of the page with respect to a target location in the scrollable area to create a parallax effect.

Abstract: A guide is configured in an authoring program to aid the user in editing objects on a document. The guide can be a horizontally or vertically oriented guide line and can be created from a single ruler, either a vertical or horizontal ruler displayed on the workspace. To create a horizontal guide, the user can position the cursor on a horizontal ruler. The user can click-and-hold and drag the cursor to create and position a horizontal guide over the workspace. To create a vertical guide, the user can position the cursor in the horizontal ruler and click and release. The user can create both vertical and horizontal guides using the vertical ruler in a corresponding manner, where clicking on the vertical ruler creates a horizontal guide, and click-and-hold and dragging creates a vertical guide. Guides can be individually configured or altered in their visual characteristics.

Abstract: A computer-animated scene illuminated by indirect light is shaded. The scene is comprised of sample locations on a surface element of an object in the scene. A point cloud representation of the scene is generated. Optionally, an importance map of the scene, based on the point cloud representation, is generated. The importance map is generated by rasterizing one or more points in the point cloud and designating areas of interest based on the energy value of the one or more points in the point cloud. A ray tracing engine is biased, based on the importance map. The biased ray tracing engine calculates the path of the ray to the sample locations in the scene to an area of interest. The scene is shaded using the output from the biased ray tracing engine.

Abstract: An interactive application may include a quasi-physical simulator configured to determine the configuration of animated characters as they move within the application and are acted on by external forces. The simulator may work together with a parameterized animation module that synthesizes and provides reference poses for the animation from example motion clips that it has segmented and parameterized. The simulator may receive input defining a trajectory for an animated character and input representing one or more external forces acting on the character, and may perform a quasi-physical simulation to determine a pose for the character in the current animation frame in reaction to the external forces. The simulator may enforce a goal constraint that the animated character follows the trajectory, e.g., by adding a non-physical force to the simulation, the magnitude of which may be dependent on a torque objective that attempts to minimize the use of such non-physical forces.
