Integration of the 3D Environment for UAV Onboard Visual Object Tracking

no code implementations6 Aug 2020 Stéphane Vujasinović, Stefan Becker, Timo Breuer, Sebastian Bullinger, Norbert Scherer-Negenborn, Michael Arens

The 3D reconstruction of the scene is computed with an image-based Structure-from-Motion (SfM) component that enables us to leverage a state estimator in the corresponding 3D scene during tracking.

Context-Driven Interactive Query Simulations Based on Generative Large Language Models

1 code implementation15 Dec 2023 Björn Engelmann, Timo Breuer, Jana Isabelle Friese, Philipp Schaer, Norbert Fuhr

The proposed query generation methods build upon recent Large Language Model (LLM) approaches and consider the user's context throughout the simulation of a search session.
