Theories of Visual Perception 3rd Edition provides clear critical accounts of several of the major approaches to the challenge of explaining how we see the world. It explains why approaches to theories of visual perception differ so widely and places each theory into its historical and philosophical context. Coverage ranges from early theories by such influential writers as Helmholtz and the Gestalt School, to more recent work in the field of Artificial Intelligence. This fully revised and expanded edition contains new material on the Minimum Principle in perception, neural networks, and cognitive brain imaging.
