Current approaches
to security detection systems (metal detectors and baggage
scanners) rely on a few independent sensors to assess
an individual's threat level. The IRIS team is developing
a prototype walk-through security portal that uses a variety
of sensors, visible, infrared and millimeter-wave images,
metal detection data, and air detection data along with
other information about the individual to determine a
threat level. We believe the fusion of all data from the
sensors will yield a more accurate assessment than any
one or more of the sensors produce individually. The team's
approach encompasses several interdisciplinary research
areas, including smart sensors, wireless sensor and data
networks, sensor placement, sensor fusion, pervasive computing,
image processing, databases and data mining. Progress
in these areas is crucial to our national security efforts
and will have a large impact in both the scientific and
industry communities.
