jagged edge

AI can detect a deepfake face because its pupils have jagged edges

New Scientist

Could this be a computer-generated face? Creating a fake persona online with a computer-generated face is easier than ever before, but there is a simple way to catch these phony pictures โ€“ look at the eyes. The inability of artificial intelligence to draw circular pupils gives away whether or not a face comes from a real photograph. Generative adversarial networks (GANs) โ€“ a type of AI that can generate images from a simple prompt โ€“ can produce realistic-looking faces.
