The eyes, the old saying goes, are the window to the soul — but when it comes to deepfake images, they might be a window into unreality.
That's according to new research conducted at the University of Hull in the U.K., which applied techniques typically used in observing distant galaxies to determine whether images of human faces were real or not. The idea was sparked when Kevin Pimbblet, a professor of astrophysics at the University, was studying facial imagery created by artificial intelligence (AI) art generators Midjourney and Stable Diffusion. He wondered whether he could use physics to determine which images were fake and which were real. "It dawned on me that the reflections in the eyes were the obvious thing to look at," he told Space.com.
