SOFTWARE TO PREVENT DEATHS
A new piece of software has been developed to detect when
crowds are starting to build up to dangerous levels. By pre-
empting riots it will then give security personnel the chance
to disperse crowds to safety. Barbara Krausz, from the
Fraunhofer Institute for Intelligent Analysis and Information
Systems in Sankt Augustin, Germany, developed the system.
She found that when people become trapped in a highly
congested area, they sway slowly from side to side in an
effort to keep their balance. The software notices this collec-
tive motion by scrutinising the movement of each pixel
between different frames of crowd video footage.
