According to new research shared by the Royal Astronomical Society, AI-generated fakes can be analyzed the same way astronomers study galaxies.
University of Hull MSc student Adejumoke Owolabi concludes that it is all about the reflection in a person’s eyes. If the reflections match, the image is likely to be that of a real human. If they don’t, they’re probably deepfakes.
“The reflections in the eyeballs are consistent for the real person, but incorrect (from a physics point of view) for the fake person,” explains Kevin Pimbblet, professor of astrophysics and director of the Centre of Excellence for Data Science, Artificial Intelligence, and Modelling at the University of Hull.
The researchers analyzed reflections of light on the eyeballs of people in real and AI-generated images. They then borrowed a method typically used in astronomy to quantify the reflections and checked for consistency between left and right eyeball reflections.
