!_ Gabriel Brostow, a former undergraduate research assistant at UNT and 1993
TAMS graduate, specializes in the computational perception of motion - analyzing
it in video, modeling it and synthesizing it. Think of it as finding, identifying and
Tracking individual needles in a moving haystack.
Researchers in England, Tel Aviv, Glasgow and Singapore who focus on group
dynamics are interested in his studies.
"We started developing an automatic system that can detect individuals in large
crowds some time before the terrorist attacks in London in 2005," Brostow says.
"We're now focusing on systems that will automatically follow individuals as they
move through the views of multiple tracking monitors."
Brostow completed his doctorate in computer science at the Georgia Institute of
Technology before going to Cambridge University in England as a Marshall Sherfield Fellow. He's conducting research
there at the Vision and Robotics Group with Roberto Cipolla, "using the power of complex mathematical algorithms."
Brostow's techniques can be applied to police work other than tracking. For example, he recently presented a
paper on the forensics of blood spatters.
"Traditionally, the study of blood spatters at a crime scene involves stretching hundreds of threads from individual
blood stains to determine trajectories," he says. "We've developed a program that can eliminate all that time-
consuming work, making the job of crime scene analysts much easier."
Not all of his research is crime-related.
"My research extends to fields as diverse as biomechanics, games, special effects and zoology," Brostow says.
William Dwyer, who earned a bachelor's degree at North Texas in 1968 and a
. , . master's in 1973, works at the Johnson Space Center in Houston, but what he works
on orbits 220 miles above the Earth. Dwyer is the system manager for the command
S and data handling system computer hardware aboard the International Space Station
ISS). He says his job can be a challenge.
"I come from a math and physics background," he says. "I was not a systems
' guy - this was a real education."
There are 31 computers on board the ISS, and four more were scheduled to go
up this fall.
"By 2010 [the year construction is due to be completed and NASA plans to
retire the Space Shuttle fleet], there will be 50 computer systems controlling every-
thing from life support to guidance and navigation, and from electrical power to payload control," Dwyer says.
The ISS is a joint project of five space agencies: NASA, the Russian Federation Space Agency, the Japan Aerospace
Exploration Association, the Canadian Space Agency and the European Space Agency. Much of Dwyer's work focuses
on joint projects with the European Space Agency. He says the two groups have different approaches to getting things
done, and they have to work together.
"For example, the European Space Agency defines the project at the very beginning to cut down on the possible
need for changes. With 13 countries involved, changes reverberate," he says. "Meanwhile, we make changes all the time
on our end of the project. We recognize this in each other. They become less rigid, and we give them enough advance
warning that a change is coming. It's a great relationship - they have a good attitude and spirit."
