Abstract: A system for storing target images for object recognition predicts a querying performance for the target image if the target image were included in a search tree of a database. The search tree has a universal search tree structure that is fixed so that it does not change with the addition of new target images. The target image is selected for inclusion or exclusion in the search tree based on the based on the querying performance, wherein the fixed tree structure of the search tree does not change if inclusion of the target image is selected.

Abstract: A multi-user augmented reality (AR) system operates without a previously acquired common reference by generating a reference image on the fly. The reference image is produced by capturing at least two images of a planar object and using the images to determine a pose (position and orientation) of a first mobile platform with respect to the planar object. Based on the orientation of the mobile platform, an image of the planar object, which may be one of the initial images or a subsequently captured image, is warped to produce the reference image of a front view of the planar object. The reference image may be produced by the mobile platform or by, e.g., a server. Other mobile platforms may determine their pose with respect to the planar object using the reference image to perform a multi-user augmented reality application.

Abstract: An improved wireless split rendering system for displaying Extended Reality (XR) content is discussed. A rendering server and client head-mounted device (HMD) may communicate over a wireless medium, where communication control is given to a server application layer logic. This allows the server to use request pose information from the HMD only when needed for rendering, while preserving bandwidth on the wireless medium for transmitting frames of the rendered content. This reduces contention and improves channel efficiency.

Abstract: A method substantially simultaneously plans a path and maps an environment by a robot. The method determines a mean of an occupancy level for a location in a map. The method also includes determining a probability distribution function (PDF) of the occupancy level. The method further includes calculating a cost function based on the PDF. Finally, the method includes simultaneously planning the path and mapping the environment based on the cost function.

Abstract: A mobile platform efficiently processes image data, using distributed processing in which latency sensitive operations are performed on the mobile platform, while latency insensitive, but computationally intensive operations are performed on a remote server. The mobile platform acquires image data, and determines whether there is a trigger event to transmit the image data to the server. The trigger event may be a change in the image data relative to previously acquired image data, e.g., a scene change in an image. When a change is present, the image data may be transmitted to the server for processing. The server processes the image data and returns information related to the image data, such as identification of an object in an image or a reference image or model. The mobile platform may then perform reference based tracking using the identified object or reference image or model.

Abstract: Disclosed are a system, apparatus, and method for depth and color camera image synchronization. Depth and color camera input images are received or otherwise obtained unsynchronized and without associated creation timestamps. An image of one type is compared with an image of a different type to determine a match for synchronization. Matches may be determined according to edge detection or depth coordinate detection. When a match is determined a synchronized pair is formed for processing within an augmented reality output. Optionally the synchronized pair may be transformed to improve the match between the image pair.

Abstract: A master device images an object device and uses the image to identify the object device. The master device then automatically interfaces with the identified object device, for example, by pairing with the object device. The master device interfaces with a second object device and initiates an interface between the first object device and the second object device. The master device may receive broadcast data from the object device including information about the visual appearance of the object device and use the broadcast data in the identification of the object device. The master device may retrieve data related to the object device and display the related data, which may be display the data over the displayed image of the object device. The master device may provide an interface to control the object device or be used to pass data to the object device.

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 determine graphics primitives of a computer graphics scene that are visible from a camera viewpoint, generate a primitive atlas that includes data representing the graphics primitives that are visible from the camera viewpoint, and shade the visible graphics primitives in the primitive atlas to produce a shaded primitive atlas. The second GPU is configured to render an image using the shaded primitive atlas.

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.
