Crime investigators often use photographic evidence to try to catch perpetrators. Face photographs could now provide investigators with more information to catch criminals, not only in the form of facial recognition, but also because pupils can reflect the appearance of the surrounding area.
The eyes are more than windows to the soul, thanks to technologies that can reveal reflected faces in pupils of photographs. Dr. Rob Jenkins of the University of York’s Department of Psychology published a study that showed how pupils in photographs of faces can be “mined” for hidden information.
