Facebook researchers have created a machine-learning system which can take an image of somebody with closed eyes and replace them with open ones.
Researchers Brian Dolhansky and Cristian Canton Ferrer note in their paper for Facebook that "face retouching algorithms" like red-eye removal and virtual makeup have become very popular. So they turned their attention to making an algorithm that could successfully replace closed eyes with open ones.
