The Renaissance-era painting, named the de Brécy Tondo, has been studied extensively for more than 40 years. Researchers from the University of Nottingham and University of Bradford used an artificial intelligence facial recognition system developed by Hassan Ugail, a professor of visual computing at Bradford, to determine its likely creator. Instead of DNA, the system uses DNN – a deep neural network – which identifies patterns in images and videos. The system...
