CVD-SfM: A Cross-View Deep Front-end Structure-from-Motion System for Sparse Localization in Multi-Altitude Scenes
Yaxuan Li, Yewei Huang, Bijay Gaudel +2
We present a novel multi-altitude camera pose estimation system, addressing the challenges of robust and accurate localization across varied altitudes when only considering sparse…
Multi-Robot Coordination with Adversarial Perception
Rayan Bahrami, Hamidreza Jafarnejadsani
This paper investigates the resilience of perception-based multi-robot coordination with wireless communication to online adversarial perception. A systematic study of this problem…
Distributed Detection of Adversarial Attacks for Resilient Cooperation of Multi-Robot Systems with Intermittent Communication
Rayan Bahrami, Hamidreza Jafarnejadsani
This paper concerns the consensus and formation of a network of mobile autonomous agents in adversarial settings where a group of malicious (compromised) agents are subject to dece…
Learning When to Use Adaptive Adversarial Image Perturbations against Autonomous Vehicles
Hyung-Jin Yoon, Hamidreza Jafarnejadsani, Petros Voulgaris
The deep neural network (DNN) models for object detection using camera images are widely adopted in autonomous vehicles. However, DNN models are shown to be susceptible to adversar…
Multi-level Adaptation for Automatic Landing with Engine Failure under Turbulent Weather
Haotian Gu, Hamidreza Jafarnejadsani
This paper addresses efficient feasibility evaluation of possible emergency landing sites, online navigation, and path following for automatic landing under engine-out failure subj…
A Modular Continuum Manipulator for Aerial Manipulation and Perching
Qianwen Zhao, Guoqing Zhang, Hamidreza Jafarnejadsani +1
Most aerial manipulators use serial rigid-link designs, which results in large forces when initiating contacts during manipulation and could cause flight stability difficulty. This…
Detection of Stealthy Adversaries for Networked Unmanned Aerial Vehicles*
Rayan Bahrami, Hamidreza Jafarnejadsani
A network of unmanned aerial vehicles (UAVs) provides distributed coverage, reconfigurability, and maneuverability in performing complex cooperative tasks. However, it relies on wi…
Privacy-Preserving Stealthy Attack Detection in Multi-Agent Control Systems
Rayan Bahrami, Hamidreza Jafarnejadsani
This paper develops a glocal (global-local) attack detection framework to detect stealthy cyber-physical attacks, namely covert attack and zero-dynamics attack, against a class of…
Learning Image Attacks toward Vision Guided Autonomous Vehicles
Hyung-Jin Yoon, Hamidreza Jafarnejadsani, Petros Voulgaris
While adversarial neural networks have been shown successful for static image attacks, very few approaches have been developed for attacking online image streams while taking into…
Detectability of Intermittent Zero-Dynamics Attack in Networked Control Systems
Yanbing Mao, Hamidreza Jafarnejadsani, Pan Zhao +2
This paper analyzes stealthy attacks, particularly the zero-dynamics attack (ZDA) in networked control systems. ZDA hides the attack signal in the null-space of the state-space rep…
Novel Stealthy Attack and Defense Strategies for Networked Control Systems
Yanbing Mao, Hamidreza Jafarnejadsani, Pan Zhao +2
This paper studies novel attack and defense strategies, based on a class of stealthy attacks, namely the zero-dynamics attack (ZDA), for multi-agent control systems. ZDA poses a fo…
