NEC Corporation (NEC; TSE: 6701) has developed the world's
first (*) "crowd behavior analysis technology" that utilizes security
camera footage to understand the behavior of crowds and to detect
abnormalities. This technology is expected to contribute to greater safety and
security through the early detection of unusual conditions and accidents.
When a large-scale facility or public space attracts a large
amount of people, there is always the risk of an unexpected incident taking
place, including accidents and acts of crime. As a result, a wide range of
heavily trafficked facilities are equipped with security cameras in order to
help prevent accidents and to minimize possible damages. However, in a crowded
environment, where hundreds of people are interacting in a complex mixture of
activity, it is difficult for conventional technologies to quickly detect and
identify the characteristics of a disturbance.
