Trends in Electronic Security and Computers fighting crime.

Automatic face detection with OpenCV.

The days of traditional surveillance are almost gone. If it is in a prison , a burglary or riots on the streets,.. electronic security, cameras and computers are the new trend, and they can see all the action.

For example, in a recent drill in a penitentiary in West Virginia five cameras tracked the “prisoners”, and artificial-intelligence software analyzed the images for face recognition, plus gestures and patterns of group behavior.  When during the drill, two groups of “inmates”  moved toward each other, the experimental computer system sent a text message  -an alert-  to a corrections officer that warned his superiors of a potential incident and gave them the exact location of the incident.

In that sense, computers have a differential advantage in comparison to regular surveillance monitors, is that the computers do not get tired or bored, they do not have to go to the toilette. The computers do not forget, they even do not blink. They are always there.

The possibilities for such computarized systems is vast.

In a high school, a computer-vision system can watch all students and prevent incidents. Can be used for the security in streets, hospitals, malls, subways, offices and stadiums.

In the future, people can take a picture of a person by using a smartphone, and obtain a facial recognition.

Computer vision allows  machines to see people, but also to reason about what themachines are seeing. That could be useful to spot spot a terrorist or a criminal.

This is the future of law enforcement, national security and military operations. they will rely mostly on observant machines. The machines will be able to  recognize, analyze and communicate what they see.  Mounted on small robots or drones, these smart machines could replace human recognition teams.
