Finding Missing Children

Face recognition CCTV systems can be used to find missing children by allowing police to add a reference photo provided by the missing child’s parents and match it with past appearances of that face captured on video.

To find the time and location where the child has been declared missing, the police will use face recognition to search video sequences (video analytics).

In this way, the police can find out where the child was last seen. A real-time alert can trigger an alarm whenever there is a match.

In 2018, Delhi police traced 3,000 missing children using the facial recognition system.

Track Criminals

Using the same face recognition CCTV systems, police can track past criminals suspected of committing a crime.

Police can use the image of past criminals from their database to detect matches in live video.

Help the Blind

Listerine has developed a face recognition app that helps blind people. The app recognizes when the people around the blind person are smiling and vibrating.

This can help blind people better understand social situations and react in a better way.

Track College Attendance

Facial recognition can be used to track college attendance. Currently, to track attendance in college, students need to sign an attendance sheet.

But, the loophole here is that any student can sign for another student who is bunking the class.

Facial recognition ensures that attendance is recorded properly by tracking every student's face. In China, tablets are used to scan students' faces and match their photos against the database.
