Real-Time fight detector algorithm
As
the number of installed CCTV cameras dramatically increases, the number
of personnel watching over them ought to be also increased. This
obviously means higher costs that many companies simply cannot afford.
As a result, the existing personnel will be in charge of the excess
number of cameras. This eventually leads to performance loss.
Our
new algorithm helps to ease
the burden of focusing the valuable attention of security personnel.
The algorithm detects fights and sends a signal when disorderly motion
patterns are detected in the video stream. The tuning of this robust
and effective algorithm is easy and mostly invariant to the
characteristics of video (spatial resolution, refresh rate, view
parameters etc.)
Automatic
detection of events
is a must in the leading video surveillance and video retrieval
systems. Our algorithm provides a valuable index key for the database
engine when searching for suspicious activities.
Current trends in the video
camera market show that in the future IP cameras will become dominant.
They transfer the video data in compressed format. Our fight detector
algorithm is suitable to operate in this compressed domain thus
achieving the multiples of real-time performance.
