Surveillance Camera System Searches Through 36 Million Faces In One Second

This surveillance camera system can search through data on 36 million faces in one second. Developed by Hitachi Kokusai Electric, the system can automatically detect a face from either surveillance footage or a regular photo, and search for it.

The search results are displayed immediately, showing thumbnail images of potential candidates. When a thumbnail is selected, the associated recorded surveillance footage can be viewed, so users can quickly review the persons actions before and after the image was taken.

"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."

With this system, it's assumed that faces are turning within around 30 degrees in the horizontal and vertical directions from the camera, and the faces are at least 40 x 40 pixels in size.

"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."

"We plan to release this system next fiscal year. We'll be handling each project individually, so if you're interested, please contact us."
