Facial regognition could be revolutionized by new light-eliminating algorithm


Facial identification in images and video is heavily dependent on light, or at least it has been up until now.

A team of researchers working out of Ben-Gurion University of the Negev has created an algorithm that can actually remove light from an image.

What this means is that if the lighting in a scene is coming heavily from behind, or above the source, the camera will still be able to identify the subject.

Interestingly for facial identification systems like FaceID, the algorithm can remove light from flat panels, meaning it would be impossible to hack the system with an image of a person on a screen.

Turning your camera into an AM radio

LIVI eliminates background light, and dynamic light, creating a steady, easily identifiable image, regardless of how erratic the lighting is.

It’s difficult to picture exactly what this looks like without a demonstration so check out the video demo from the team below:

This has obvious application in facial recognition systems used to unlock phones and in animoji, but also in home security where low-light or high-contrast lighting could mean you’re left unable to identify a burglar.

The algorithm works like an AM radio, effectively ‘tuning out’ the unwanted signal.
