SurveillanceNew surveillance system: 1 second to search through 36 million faces
New surveillance camera system can search through data on thirty-six million faces in one second
A new surveillance camera system can search through data on thirty-six million faces in one second. Developed by Hitachi Kokusai Electric, the camera can automatically detect a face from either surveillance footage or a regular photo, and search for it.
DigInforeports that the search results are displayed immediately, showing thumbnail images of potential matches. When a thumbnail is selected, the associated recorded surveillance footage can be viewed, so users can quickly review the person’s actions before and after the image was taken.
DigiInfonotes that with the new system, it is 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.
Hitachi says the system is suitable for customers that have a relatively large-scale surveillance system, such as railways, power companies, law enforcement, and large stores.
