The Science of Land Target Spectral Signatures
Rama Chellappa, Joshua Broadwater
This project is a collaboration with the Georgia Institute of Technology, University of Hawaii, Rochester Institute of Technology, Clark Atlanta University, and University of Florida. The Multiple
University Research Initiative (MURI) team is focused on understanding
the physical phenomena that affect target spectral signatures such as
weathering, atmospheric effects, and camera position. Our part of the
project focuses on incorporating physical phenomena into automatic target
detection/recognition (ATD/R) algorithms for hyperspectral imagery. Our
past research has provided improved parametric detectors that incorporate
sum-to-one and non-negativity abundance constraints. Our current research
revolves around the development of physics-based kernels for
non-parametric detectors and the development of advanced adaptive
threshold techniques based on importance sampling.
Algorithms and Architectures For Vision Based Inference From Distributed Cameras
This project is a collaboration with Dr.Shuvra Bhattacharya and Dr.Wayne Wolf .This project
develops new techniques for distributed smart camera networks through an
integrated exploration of distributed algorithms, embedded architectures,
and software synthesis techniques. The objective is to build real time
systems for coordinated inference from multiple cameras. Specifically, we
are investigating a series of complex smart camera algorithms and
applications, specifically, human gesture recognition; self-calibration of
the distributed camera network; detection, tracking and fusion of
trajectories using distributed cameras; view synthesis using image based
visual hulls; gait-based human recognition; and human activity analysis.
New Technology for Capture, Analysis and Visualisation of Human Movement Using Distributed Cameras
This project is a collaboration with the Biomotion Laboratory at Stanford University and the Media Research Laboratory at New York University.
The objective is to perform markerless motion capture using multiple
calibrated cameras. We use shape models such as super-quadrics to
represent the humans. Such models are essential for tracking the
articulated motion accurately.
Insect Inspired Navigation of Micro Air Vehicles
project aims at developing autonomous Micro Air Vehicles capable of
navigation and terrain understanding. The project is a collaboration
with Aerospace Engineering , Mechanical Engineering Departments at the University of Maryland and Visual Sciences Group at Australian National University.
Current focus is on the following issues.
- Estimating the ego-motion of Micro Air Vehicles(MAV) from a
combination of visual and inertial sensors.
- Terrain Understanding from videos acquired from MAVs.
- Simultaneous tracking and Behavior analysis of social insects.
Multi-sensor Multi-nodal Fusion for Audio-Video Survillence
This project is a collaboration with BAE Systems and Prof. Jim McClellan of
Georgia Institute of Technology. This project addresses issues related to surveillance and outdoor scene monitoring and develops algorithms for the following.
- Develop PDA based remote sentry devices for monitoring scene acoustic and video through secure wireless networks.
Multi-nodal Multi-sensor fusion for robust tracking with efficient use
of the individual modality for low power consumption and prolonged
- Multi-camera tracking (especially for non-overlapping views).
