    • Visibility Cues for Communication Aware Guidance in Cluttered Environments 

      Christmann, Hans Claus; Johnson, Eric N. (Georgia Institute of TechnologySpringer Berlin Heidelberg, 2011)
      This paper presents the usage of visibility based guidance cues in order to find waypoints useful for maintaining communication in a multi UAV (Uninhabited Aerial Vehicle), single operator system. Based upon the overlay ...
    • Vision-based Target Tracking with Adaptive Target State Estimator 

      Sattigeri, Ramachandra J.; Johnson, Eric N.; Calise, Anthony J.; Ha, Jin-Cheol (Georgia Institute of TechnologyAmerican Institute of Aeronautics and Astronautics, Inc., 2007-08)
      This paper presents an approach to vision-based target tracking with a neural network (NN) augmented Kalman filter as the adaptive target state estimator. The vision sensor onboard the follower (tracker) aircraft is a ...
    • Vision-Only Aircraft Flight Control 

      De Wagter, Christophe; Proctor, Alison A.; Johnson, Eric N. (Georgia Institute of Technology, 2003-10)
      Building aircraft with navigation and control systems that can complete flight tasks is complex, and often involves integrating information from multiple sensors to estimate the state of the vehicle. This paper describes ...
    • Visual Marker Detection In The Presence Of Colored Noise for Unmanned Aerial Vehicles 

      Shah, Syed Irtiza Ali; Wu, Allen D.; Johnson, Eric N. (Georgia Institute of TechnologyAmerican Institute of Aeronautics and Astronautics, Inc., 2010-04)
      This paper develops a vision-based algorithm to detect a visual marker in real time and in the presence of excessive colored noise for Unmanned Aerial Vehicles. After using various image analysis techniques, including ...
    • The Zermelo-Voronoi Diagram: a Dynamic Partition Problem 

      Bakolas, Efstathios; Tsiotras, Panagiotis (Georgia Institute of TechnologyElsevier, 2010)
      We consider a Voronoi-like partition problem in the plane for a given finite set of generators. Each element in this partition is uniquely associated with a particular generator in the following sense: An agent that resides ...
