“It is with our faces that we face the world, from the moment of birth to the moment of death. Our age and our sex are printed on our faces. Our emotions, the open and instinctive emotions which Darwin wrote about, as well as the hidden or repressed ones which Freud wrote about, are displayed on our faces, along with our thoughts and intentions.”

Oliver Sacks, The Mind’s Eye


“Once again, getting computers to “see” the face involves building into these systems particular ways of seeing, rather than creating a technically neutral form of machine vision that is free from the ambiguities, imperfections, and subjective capacities of human visual perception.”
