摘要： Systems and techniques are described for extended reality (XR) operations. An XR system displays virtual content using a display according to display settings. The display settings can identify, for instance, a position, orientation, and/or size of the virtual content as displayed. The environment can be viewable using the display as the virtual content is displayed by the display, for example using a see-through display or a pass-through display. The imaging system can determine, based on one or more attributes of one or both eyes of the user of the imaging system, an extent of perception of the virtual content that is displayed using the display by the user. The attributes can identify, for instance, eye position, eye movement, pupil dilation, saccades, fixations, blinking, and/or squinting. The XR system can determine, based on the extent of perception of the virtual content by the user, a modification to the display settings.

摘要： The present disclosure relates to methods and apparatus for display or graphics processing. Aspects of the present disclosure can calculate first location information based on a first image mesh. Further, aspects of the present disclosure can determine a first UV image based on the calculated first location information. Additionally, aspects of the present disclosure can calculate second location information based on a second image mesh and the determined first UV image. Aspects of the present disclosure can also determine a second UV image based on the calculated second location information. Aspects of the present disclosure can also generate a third image mesh based on the determined second UV image. Also, aspects of the present disclosure can calculate third location information based on the third image mesh and a camera image. Aspects of the present disclosure can also determine a display image based on the calculated third location information.

摘要： Examples are described for overlaying primitives, arranged as concentric circles, in circular images onto respective mesh models to generate rectangular images representative of a 360-degree video or image. Portions of the rectangular images are blended to generate a stitched rectangular image, and image content for display is generated based on the stitched rectangular image.

摘要： Systems, methods, and non-transitory media are provided for generating private control interfaces for extended reality (XR) experiences. An example method can include determining a pose of an XR device within a mapped scene of a physical environment associated with the XR device; detecting a private region in the physical environment and a location of the private region relative to the pose of the XR device, the private region including an area estimated to be within a field of view (FOV) of a user of the XR device and out of a FOV of a person in the physical environment, a recording device in the physical environment, and/or an object in the physical environment; based on the pose of the XR device and the location of the private region, mapping a virtual private control interface to the private region; and rendering the virtual private control interface within the private region.

摘要： A method performed by an electronic device is described. The method includes obtaining one or more trip objectives. The method also includes obtaining one or more evaluation bases. The method further includes identifying an association between at least one site and the one or more trip objectives. The method additionally includes obtaining sensor data from the at least one site. The sensor data includes at least image data. The method also includes performing analysis on the image data to determine dynamic destination information corresponding to the at least one site. The method further includes performing trip planning based on the dynamic destination information, the one or more trip objectives, and the one or more evaluation bases. The method additionally includes providing one or more suggested routes based on the trip planning.

摘要： Techniques and systems are provided for processing one or more images. In one example, a method of processing a plurality of images comprises: obtaining a first image captured using a first aperture setting; obtaining a second image captured using a second aperture setting, the first aperture setting being associated with a smaller aperture size than an aperture size associated with the second aperture setting; detecting pixels of the first image having lens flare; and generating an output image by combining the first image and the second image, the first image and the second image being combined by replacing the pixels of the first image having the lens flare with corresponding pixels of the second image.

摘要： Examples are described for overlaying circular images onto a three-dimensional mesh model to generated respective portions of image content for 360-degree viewable content, where each of the portions is a sub-capsule that is larger than half of the sphere. The portions are rendered and then blended based on overlapping portions of the image content from the 360-degree viewable content.

摘要： In general, techniques are described that facilitate processing of a depth map image in mobile devices. A mobile device comprising a depth camera, a camera and a processor may be configured to perform various aspects of the techniques. The depth camera may be configured to capture a depth map image of a scene. The camera may include a linear polarization unit configured to linearly polarize light entering into the camera. The camera may be configured to rotate the linearly polarization unit during capture of the scene to generate a sequence of linearly polarized images of the scene having different polarization orientations. The processor may be configured to perform image registration with respect to the sequence of linearly polarized images to generate a sequence of aligned linearly polarized images, and generate an enhanced depth map image based on the depth map image and the sequence of aligned linearly polarized images.
