Abstract: Methods, systems, computer-readable media, and apparatuses for assigning a color class of a defined finite set of colors to at least one sub-region within a test image are presented. A plurality of sub-regions are identified within a test image. A first sub-region color value is determined for a selected first sub-region of the test image. Using the first sub-region color value and a plurality of zero-order probability distributions, a first color class of the defined finite set of colors is determined as a hypothesis color for the first sub-region. A second sub-region color value is determined for a selected second sub-region of the test image. Using the second sub-region color value and a conditional probability distribution conditioned on the hypothesis color for the first sub-region, a second color class of the defined set of colors is determined. The second color class is assigned to the second sub-region.

Abstract: Embodiments disclosed facilitate resource utilization efficiencies in Mobile Stations (MS) during 3D reconstruction. In some embodiments, camera pose information for a first color image captured by a camera on an MS may be obtained and a determination may be made whether to extend or update a first 3-Dimensional (3D) model of an environment being modeled by the MS based, in part, on the first color image and associated camera pose information. The depth sensor, which provides depth information for images captured by the camera, may be disabled, when the first 3D model is not extended or updated.

Abstract: A mobile device uses vision and orientation sensor data jointly for six degree of freedom localization, e.g., in wide-area environments. An image or video stream is captured while receiving geographic orientation data and may be used to generate a panoramic cylindrical map of an environment. A bin of model features stored in a database is accessed based on the geographic orientation data. The model features are from a pre-generated reconstruction of the environment produced from extracted features from a plurality of images of the environment. The reconstruction is registered to a global orientation and the model features are stored in bins based on similar geographic orientations. Features from the panoramic cylindrical map are matched to model features in the bin to produce a set of corresponding features, which are used to determine a position and an orientation of the camera.

Abstract: Systems and techniques are described herein for processing frames. The systems and techniques can be implemented by various types of systems, such as by an extended reality (XR) system or device. In some cases, a process can include obtaining feature information associated with a feature in a current frame, wherein the feature information is based on one or more previous frames; determining an estimated pose of the apparatus associated with the current frame; obtaining a distance associated with the feature in the current frame; and determining an estimated scale of the feature in the current frame based on the feature information associated with the feature, the estimated pose, and the distance associated with the feature.

Abstract: Techniques are provided for generating three-dimensional models of objects from one or more images or frames. For example, at least one frame of an object in a scene can be obtained. A portion of the object is positioned on a plane in the at least one frame. The plane can be detected in the at least one frame and, based on the detected plane, the object can be segmented from the plane in the at least one frame. A three-dimensional (3D) model of the object can be generated based on segmenting the object from the plane. A refined mesh can be generated for a portion of the 3D model corresponding to the portion of the object positioned on the plane.

Abstract: Systems, methods, and non-transitory media are provided for generating virtual private spaces for extended reality (XR) experiences. An example method can include initiating a virtual session for presenting virtual content and identifying, for the virtual session, a portion of a physical space for use as a virtual private space for presenting at least a portion of the virtual content. The method can include outputting boundary information defining a boundary of the virtual private space, and generate at least the portion of the virtual content for the virtual private space. At least the portion of the virtual content is viewable in the virtual private space by one or more authorized users of the virtual session and is not viewable by one or more unauthorized users.
