  • AUTOMATED MESH GENERATION
    Publication number: 20200286285
    Abstract: Various techniques associated with automatic mesh generation are disclosed. One or more center curves of an outline of an object or figure are first determined. Next, for each of a plurality of points of each of the one or more center curves, a pair of rays is cast from a center curve in opposite directions, wherein the rays collide with opposite sides of the outline, and a collision pair is generated that comprises a line connecting collision points of the pair of rays on opposite sides of the outline. A mesh model of the object or figure is generated by mapping each of a set of collision pairs to polygons used to define the mesh model.

  • ADAPTIVE SAMPLING OF PIXELS
    Publication number: 20200279430
    Abstract: Adaptive sampling of pixels is disclosed. In some embodiments, a rendering of a scene is generated by sampling each pixel of the rendering with a prescribed number of samples. Subsequently, those pixels of the rendering that do not satisfy a noise threshold are iteratively sampled with an additional sample during each iteration until all pixels of the rendering satisfy the noise threshold. The noise threshold is associated with noise arising due to under sampling. Pixels comprising the completed rendering are not uniformly sampled.

  • Machine learning based image processing techniques
    Patent number: 10762605
    Abstract: A machine learning based image processing architecture and associated applications are disclosed herein. In some embodiments, a machine learning framework is trained to learn low level image attributes such as object/scene types, geometries, placements, materials and textures, camera characteristics, lighting characteristics, contrast, noise statistics, etc. Thereafter, the machine learning framework may be employed to detect such attributes in other images and process the images at the attribute level.

  • Arbitrary view generation
    Patent number: 10748265
    Abstract: Techniques for generating an arbitrary ensemble view from existing views of a plurality of scenes are disclosed. In some embodiments, for each of a plurality of scenes, each of a corresponding set of one or more views is normalized to a desired perspective if its existing perspective is different than the desired perspective. An ensemble view comprising the plurality of scenes that has the desired perspective is generated at least in part using pixels from views of the scenes having the desired perspective including the normalized views.

  • Two-dimensional compositing
    Patent number: 10679539
    Abstract: Two-dimensional compositing that preserves the curvatures of non-flat surfaces is disclosed. In some embodiments, a mapping is associated with a two-dimensional rendering that maps a potentially variable portion of the two-dimensional rendering to a canvas. The mapping is generated from a three-dimensional model of the potentially variable portion of the two-dimensional rendering. The potentially variable portion of the two-dimensional rendering is dynamically modified according to the mapping to reflect content comprising the canvas or edits received with respect to the canvas.

  • Rendering a modeled scene
    Patent number: 10462499
    Abstract: Techniques for rendering a modeled scene are disclosed. In some embodiments, a database comprising locally available generic object definitions is maintained at a destination device at which a scene is desired to be rendered. A scene is rendered by configuring one or more locally available generic object definitions obtained from the database according to a received specification of a modeled scene, wherein rendering is constrained to rendering locally available objects whose definitions are included in the database.

  • Generating video content
    Patent number: 10430992
    Abstract: Improved techniques for generating video content are disclosed. In some embodiments, a frame is first rendered using a first rendering option. It is then determined whether the frame is an independent frame (I-frame) or a predictive frame (P-frame). In the event that the frame is an I-frame, the frame is rendered using a second rendering option. In the event that the frame is a P-frame, the frame as rendered by the first rendering option and a previous frame as rendered by the first rendering option are used to determine prediction error. The first rendering option comprises a lower computational complexity than the second rendering option.

  • VIRTUALIZING CONTENT
    Publication number: 20190221042
    Abstract: Techniques for virtualizing content are disclosed. One or more objects comprising source video content are determined. The one or more objects comprising the source video content are virtualized by mapping each to and representing each with a corresponding database object. Data comprising the corresponding database objects is provided for rendering the source video content instead of any original pixel information of the source video content so that a virtualized version of the source video content is rendered.

  • BLENDED PHYSICAL AND VIRTUAL REALITIES
    Publication number: 20190130604
    Abstract: Techniques for providing blended physical and virtual reality experiences are disclosed. In some embodiments, a pose of a camera of a device located in a venue is determined based at least in part on three-dimensional asset recognition in a field of view of the camera, wherein the field of view of the camera comprises an actual physical view of the venue; a virtual view corresponding to the actual view is obtained from existing assets comprising a specification of a virtualized version of the venue; and display of the virtual view is facilitated at the venue. Thus, a virtual reality of a physical space is provided while at the physical space based on actual three-dimensional objects detected or recognized in the physical space.

  • ALIGNED AUGMENTED REALITY VIEWS
    Publication number: 20190130637
    Abstract: Techniques for generating aligned, augmented reality views are disclosed. In some embodiments, an estimate of a floorplan of a three-dimensional space is first generated based on one or more views of the three-dimensional space from a camera of a device located in the three-dimensional space. A cost function is next minimized with respect to the estimate of the floorplan to generate a corrected floorplan having less error than the estimated floorplan, and a camera pose corresponding to the corrected floorplan is determined. Display of a rendering having the determined camera pose is facilitated in an actual view of the camera, resulting in an aligned, augmented reality view.

In some embodiments, for each image of a set of images associated with a scene, image pixels are divided into a plurality of pixel blocks, the pixel blocks are transformed into an arbitrary perspective, and pixels of an image array comprising the arbitrary perspective are populated with corresponding pixels from the transformed pixel blocks. An output image of the scene comprising the arbitrary perspective is then generated based at least in part on the populated image array.
