Law enforcement agencies around the world use technology to equip themselves to stop crime or to improve their response time. Most of them send drones to monitor large groups of people or a large area of interest with limited staff.
Although very useful, this technology is limited to one factor: the ability to determine what is normal and what is not.
They can only forward the videos to their supervisors who will decide what action to take. Therefore, a team of Czech scientists has decided to give these machines the ability to detect suspicious behavior.
They claim to have developed a monitoring system that analyzes drone images in a manner similar to the human brain.
Developed as a joint research program between Brno University of Technology and the Czech Republic police, the new system uses neural networks to clarify data.
In addition to crowd monitoring and control, it could also be used for vehicle management, say scientists.
David Bažout, a recent graduate of Information Technology University, explained how he and his colleagues developed the program.
Czech Scientists Provide ‘Brain’ to Drone System to Detect Unusual Behavior
He told Radio Prague International that drone drawings were divided into smaller “cells”. The system then analyzes and creates a general picture of what is happening.
It then develops a standard behavior model in a given area and compares the negative, if any, reporting to the observer.
The main advantage of this program is that it reads and uses the program in real time, eliminating the possibility of critical time loss in building a police response.
During the experiment, scientists asked the system to monitor soccer players on the field. Some of them were suddenly told to lie down.
The system alerted the viewer immediately to inaccuracies, according to the report.
But there can be many differences in the crowd as everyone is expected to behave differently.
Bažout and his team therefore gave the system indicator the opportunity to set the sensitivity level.
Czech police are now said to be launching their tests to see how the system works, in the hope that it will allow its officials to reach the scene as soon as possible.
