Automatic detection of threats based on video analysis video demonstration

A new demonstration video has been uploaded on YouTube. This one shows how the detection of threats based on video analysis for city security systems is done.

In the video the dangerous event detection process is presented. First, image analysis is performed for moving objects detection. The object is separated from the background and its movement is analyzed. Then, based on changes of movement speed and direction, various potentially dangerous events can be detected.
In presented sample an event "robbery" is defined as:
- first a meeting of two moving objects A and B occurs,
- then rapid change of speed and direction of A's movement happens (escape),
- it is followed by B running after A (moving fast in direction of A's escape).

When such potentially dangerous event is automatically detected by video analysis algorithm, the video clip containing whole event is transmitted to the security system operator for verification. The operator verifies the alarm, confirms the event and decides what should be done next.
