Abstract: Examples are described for processing images to mask dynamic objects out of images to improve feature tracking between images. A device receives an image of an environment captured by an image sensor. The image depicts at least a static portion of the environment and a dynamic object in the environment. The device identifies a portion of the image that includes a depiction of the dynamic object. For example, the device can detect a bounding box around the dynamic object, or can detect which pixels in the image correspond to the dynamic object. The device generates a masked image at least by masking the portion of the image. The device identifies features in the masked image, and uses the features from the masked image for feature tracking from other images of the environment, masked or otherwise. The device can use this feature tracking for mapping, localization, and/or relocation.

Abstract: Systems and techniques are described herein for processing images. 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 first processor receives an image of an environment captured by an image sensor, identifies features depicted in the image, and generates descriptors for the features. The first processor sends the descriptors to a second processor, which may be more powerful than the first processor. The second processor receives the descriptors. The second processor associates the plurality of features with a map of the environment based on at least a subset of the plurality of descriptors. For example, the second processor can track at least a subset of the features based on at least a subset of the descriptors and based on feature information from one or more additional images of the environment.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced beam management using extended reality (XR) perception data. In a first aspect, a method of wireless communication includes establishing a communication connection between a user equipment (UE) and a serving base station using a current serving beam selected by the UE from a plurality of available beams paired with a serving base station beam. The method further includes obtaining, perception information from one or more extended reality sensors associated with the UE and determining, in response to detection of UE movement, a transpositional representation of the movement using the perception information. The UE may then select a new serving beam in accordance with the transpositional representation. Other aspects and features are also claimed and described.

Abstract: Systems and techniques are described for token device transfer management. A system identifies, in a payload of at least one block of a distributed ledger, a token corresponding to media content. A parameter of the token in the distributed ledger indicates that the token is associated with a first user. The system identifies a device that is associated with the token and the media content. The device is also associated with the first user. The system identifies that the device has been relocated to an area associated with a second user. In response to identifying that the device has been relocated to the area, the system causes the parameter of the token in the distributed ledger to be modified from indicating that the token is associated with the first user to indicating that the token is associated with the second user.

Abstract: Systems and techniques are described for situational token-associated media output. A system receives sensor data captured by at least one sensor of a media device. The system identifies, based on the sensor data, a relationship between the media device and an anchor element that is associated with a token. The system identifies the token in a payload of at least one block of a distributed ledger. The token corresponds to media content according to the distributed ledger. The system generates a representation of the media content corresponding to the token. In response to identifying the relationship between the media device and the anchor element, the system outputs the representation of the media content.

Abstract: Systems and techniques are described for situational token generation. A system receives media content that is based on sensor data captured by at least one sensor of a media device.

In response to determining that the position of the media device is within the geographic area, the system generates a token corresponding to the media content. A payload of at least one block of a distributed ledger identifies the token.

Abstract: Methods, systems, and devices for head wearable display devices are described. A device may capture a set of images over a set of orientations using a set of cameras positioned on an outward facing surface of the device. The set of images include a first subset of images captured by a first camera and a second subset of images captured by a second camera. The device may detect a set of facial features in each of the first subset of images and the second subset of images, and measure a set of inter-pupillary distances over the set of orientations based on the set of facial features in each of the first and second subset of images. The device may determine an inter-pupillary distance parameter based on aggregating the set of inter-pupillary distances over the set of orientations. The device may calibrate based on the inter-pupillary distance parameter.
