VideoTrek: A Vision System for a Tag-Alone Robot
We present a system that combines multiple visual navigation techniques to achieve GPS-denied, non-line-of-sight SLAM capability for heterogeneous platforms.

Pedestrian Association and Localization in Monocular FIR Video Sequence
This paper addresses the frame-to-frame data association and state estimation problems in localization of a pedestrian relative to a moving vehicle from a monocular far infra-red video sequence.

Tools for Planning and Coordinating Development of Medical Countermeasures in the Public Sector
We have developed a set of software tools and methods for using them that could support the desired coordination and that could also provide for more rapid, comprehensive, and shared…

Real-Time Vehicle Detection for Highway Driving
We present a new multi-stage algorithm for car and truck detection from a moving vehicle. The algorithm performs a search for pertinent features in three dimensions, guided by a ground…

Remote Oxygen Sensing By Ionospheric Excitation (ROSIE)
We can demonstrate an approach to remotely detect O-atoms at the altitudes relevant to IM experiments, which we call remote oxygen sensing by ionospheric excitation (ROSIE).
-
Weapon Identification Using Hierarchical Classification of Acoustic Signatures
We apply a unique hierarchical audio classification technique to weapon identification using gunshot analysis.

Communication Pattern Anomaly Detection in Process Control Systems
To protect these process control systems, we present a learning-based approach for detecting anomalous network traffic patterns.

ACT-Vision Active Collaborative Tracking for Multiple PTZ Cameras
We describe a novel scalable approach for the management of a large number of Pan-Tilt-Zoom (PTZ) cameras deployed outdoors for persistent tracking of humans and vehicles, without resorting to the…

Infrastructure Free 6 DOF Location and Pose Estimation for Mixed Reality Systems
Mixed reality training systems using Head Mounted Displays (HMDs) require very high precision knowledge of the 3D location and 3D orientation of the user's head.

Laboratory Measurement of the Co Cameron Bands and Visible Emissions Following Vuv Photodisassociation of CO2
The experimental results confirmed that once a triplet state excitation threshold is exceeded, a fraction of the Cameron band emission is accompanied by visible emission.
