Abstract: A computer-implemented method for the detection and recognition of objects in unlabeled image data using an automated labelling architecture. The method includes the steps of: proposing bounding-box in every image of the unlabeled image data using a task specific and/or a related task pretrained object detection model and a Bounding Box Sampler module; filtering said bounding boxes for positive object instances; assigning to said filtered bounding boxes a class label using a Few-Shot Classification module; and modifying filtered bounding boxes based on additional class wise attention output from the Few-Shot Classification module.

Abstract: An AI based change detection system for executing a method to detect changes in geo-tagged videos to update HD maps, the method employing a neural network of modular components including a keyframe extraction module for processing two or more videos relating to separate traversals of an area of interest to which the HD map which is to be updated relates, a deep neural network module processing output of the keyframe extraction module, a change detection module processing output of the deep neural network module, and an auxiliary computations module which is designed to aid the change detection module.
