Zusammenfassung
Surveillance cameras are today a common sight
in public spaces and thoroughfares, where they are used to
prevent crime and monitor traffic. However, human operators
have limited attention spans and may miss anomalies. Here,
we develop an intelligent surveillance system on the basis of
spatio-temporal information in comprehensive flow of human
traffic. The comprehensive flow is extracted from optical flows,
and anomalies are identified on the basis of the spatiotemporal
distribution. Because our system extracts only a few anomalies
from many surveillance cameras, operators will not miss the
important scenes. In experiment, we confirmed effectiveness of
our intelligent surveillance system.
