The Japanese company Hitachi Kokusai Electric has developed a monitoring system that automatically detects faces in still images or video. It can also search for the same faces in content from other surveillance cameras.

A system to recognize faces is nothing new, but Hitachi’s new surveillance camera is capable of comparing faces with a speed of 36 million faces per second. In theory, the system can search the entire world population in just over three minutes.

“This high speed is achieved by detecting faces through image recognition when the footage from the camera is recorded, and also by grouping similar faces.”

Hitachi system assumes that all face images it detects at least 40 x 40 pixels in size and that faces are turned towards the camera enough, both vertically and horizontally.

The technology delivers search results in real time, in the form of thumbnails. When you click on one of these images, you will be able to see footage of what this person did both before and after the still image was taken.

“We think this system is suitable for customers that have a relatively large-scale surveillance system, such as railways, power companies, law enforcement, and large stores.”

The company plan to release this system next year, and they will be handling each project individually, so if you’re interested you can contact the company.
