Today, you can buy palm-sized organisers
for $250 that link to computers, transmit data, and
store thousands of addresses, appointments, memos, lists,
and e-mails. The keys to this stunning revolution in
personal power are the transistor and the integrated
circuit -- the centrepieces of the modern electronics
systems that swept the world in the last half of the
Where will microchips appear next? They
might appear on the front of refrigerators to monitor
food supplies and send grocery lists to the store, automatically
charging credit cards or bank accounts. Or they could
be implanted in children to prevent kidnapping, or inside
the human brain to cure blindness or other medical conditions.
The technology is limitless. Only imagination will govern
Signal Processing and Media Applications Team
The act of extracting useful information from sometimes
poor data is usually called "Signal processing".
This area has devloped rapidly in the last 25 years
because of the rise of the comsumer PC. Products like
DVD Players, Digital television, CD Players and even
the automobile, rely on basic signal processing ideas
for their operation.
In DVD and Digital Multimedia players
in general, the data is stored in compressed format
in order to allow an entire movie to fit onto the limited
space available. It is amazing to think that just 10
years ago, the elements of the MPEG video compression
standard like Motion tracking, were just ideas in research
laboratories spread around the world. Signal processing
in automobiles is used for cancelling the noise from
the engine and automated engine tuning, for instance.
Daimler-Chrysler used video analysis
to track air flows inside the cabin and evaluate the
effect of window shape and temperature on that "draught
of air" that exists between the driver's shoulder
and the window. Image and Video processing is a very
interesting area in Signal processing, and the group
in the Electronics and Electrical Engineering Department,
"The Signal processing and media applications group"
has been involved in a wide variety of projects. The
demonstrations below show what could be achieved through
some simple mathematical interpretation of video data.
