US 2026/0212528 A1 · JOINT BITRATE ADAPTATION AND FEATURE EXTRACTION FOR EDGE-ASSISTED LOCALIZATION OF MOBILE DEVICES

Abstract

Systems and methods are disclosed for joint bitrate adaptation and feature extraction for server-assisted localization of mobile devices. In one embodiment, a method performed by a mobile device comprises obtaining an image of an environment in which the mobile device is located, determining a desired bitrate for compression of the image, and determining whether one or more criteria for transmission of the image at the desired bitrate are satisfied. The method further comprises, if the criteria are not satisfied, performing a feature extraction procedure that detects features in the image and provides feature information comprising information that describes the detected features and information that indicates locations of the features within the image and transmitting the feature information to the associated server. The method further comprises, if any of the criteria are satisfied, compressing the image at the desired bitrate and transmitting the compressed image to the associated server.

A method performed by a mobile device for server-assisted localization and mapping, the method comprising:

obtaining an image of an environment in which the mobile device is located from an associated camera;
determining a desired bitrate for compression of the image based on one or more network conditions of a wireless network over which the mobile device is to transmit the image to an associated server for server-assisted localization and mapping;
