Abstract: The present disclosure relates to methods and apparatus for graphics processing. Aspects of the present disclosure may identify a first content group and a second content group in a scene. Further, aspects of the present disclosure may determine whether at least a portion of the first content group occludes or potentially occludes at least a portion of the second content group. Additionally, the present disclosure may represent the first content group and the second content group based on the determination whether at least a portion of the first content group occludes or potentially occludes at least a portion of the second content group. In some aspects, the first content group may include at least some real content and the second content group includes at least some augmented content. The present disclosure may also render at least a portion of surfaces of the first content group using an occlusion material.

Abstract: An example system includes a first computing device comprising a first graphics processing unit (GPU) implemented in circuitry, and a second computing device comprising a second GPU implemented in circuitry. The first GPU is configured to perform a first portion of an image rendering process to generate intermediate graphics data and send the intermediate graphics data to the second computing device. The second GPU is configured to perform a second portion of the image rendering process to render an image from the intermediate graphics data. The first computing device may be a video game console, and the second computing device may be a virtual reality (VR) headset that warps the rendered image to produce a stereoscopic image pair.

Abstract: A method performed by an apparatus is described. The method includes receiving a set of image frames including at least one object. The method also includes receiving a camera position for each image frame. The method further includes associating the at least one object between image frames based on one or more object points and the received camera position for each image frame to produce two-dimensional (2D) object location data. The method additionally includes estimating three-dimensional (3D) pose data of the at least one object based on the 2D object location data. The method also includes refining the 3D pose data based on a shape constraint.

Abstract: Disclosed are a system, apparatus, and method for monocular visual simultaneous localization and mapping that handles general 6DOF and panorama camera movements. A 3D map of an environment containing features with finite or infinite depth observed in regular or panorama keyframes is received. The camera is tracked in 6DOF from finite, infinite, or mixed feature sets. Upon detection of a panorama camera movement towards unmapped scene regions, a reference panorama keyframe with infinite features is created and inserted into the 3D map. When panoramic camera movement extends toward unmapped scene regions, the reference keyframe is extended with further dependent panorama keyframes. Panorama keyframes are robustly localized in 6DOF with respect to finite 3D map features. Localized panorama keyframes contain 2D observations of infinite map features that are matched with 2D observations in other localized keyframes. 2D-2D correspondences are triangulated, resulting in new finite 3D map features.

Abstract: Disclosed are a system, apparatus, and method for 3D object segmentation within an environment. Image frames are obtained from one or more depth cameras or at different times and planar segments are extracted from data obtained from the image frames. Candidate segments that comprise a non-planar object surface are identified from the extracted planar segments. In one aspect, certain extracted planar segments are identified as comprising a non-planar object surface, and are referred to as candidate segments. Confidence of preexisting candidate segments are adjusted in response to determining correspondence with a candidate segment. In one aspect, one or more preexisting candidate segments are determined to comprise a surface of a preexisting non-planar object hypothesis. Confidence in the non-planar object hypothesis is updated in response to determining correspondence with a candidate segment.

Abstract: Exemplary methods, apparatuses, and systems for performing wide area localization from simultaneous localization and mapping (SLAM) maps are disclosed. A mobile device can select a first keyframe based SLAM map of the local environment with one or more received images. A respective localization of the mobile device within the local environment can be determined, and the respective localization may be based on the keyframe based SLAM map. The mobile device can send the first keyframe to a server and receive a first global localization response representing a correction to a local map on the mobile device. The first global localization response can include rotation, translation, and scale information. A server can receive keyframes from a mobile device, and localize the keyframes within a server map by matching keyframe features received from the mobile device to server map features.

Abstract: A source video stream is processed to extract a desired object from the remainder of video stream to produce a segmented video of the object. Additional relevant information, such as the orientation of the source camera for each frame in the resulting segmented video of the object, is also determined and stored. During replay, the segmented video of the object, as well as the source camera orientation are obtained. Using the source camera orientation for each frame of the segmented video of the object, as well as target camera orientation for each frame of a target video stream, a transformation for the segmented video of the object may be produced. The segmented video of the object may be displayed over the target video stream, which may be a live video stream of a scene, using the transformation to spatially register the segmented video to the target video stream.
