Intelligent vision
Surveillance cameras developed by
Dr. Visvanathan Ramesh () are en-
abling security personnel in public spac-
es such as subway stations and airports
to respond to dangerous situations faster
and more effectively. Using new, com-
plex algorithms for electronic image rec-
ognition, the innovative smart cameras
can assess potential dangers automati-
cally and instantaneously.
Lower radiation exposure
Dr. Rainer Raupach () has optimized
image evaluation in computed tomogra-
phy systems by developing algorithms
that generate top-quality data from even
poor images. As a result, the same amount
of information can now be obtained with
up to  percent less radiation exposure.
Failsafe power lines
Dr. Tevfik Sezi () has created a new
way to measure power transmission that
makes power lines less subject to failure
and helps reduce transmission losses. In-
struments at both ends of a power line
measure the current flowing through the
line at precisely the same time, identify-
ing any deviations that require corrective
action. The method also helps detect and
eliminate small current leakages.
“Our Environmental Portfolio
includes some 14,000 patents –
further testimony to our
researchers’ power of innovation.”
