Professor Colin Blakemore presents a fascinating insight to all the major topics in visual science research. Experts from around the world show how this vast subject can be unified from the viewpoint that describes the way in which visual systems efficiently encode and represent the outside world. The approach, which is both rigorous and general, was championed by H. B. Barlow in the fifties and has recently acquired a new significance in the light of exciting developments in computer science and artificial intelligence and vision. The book is essential reading for advanced undergraduates, postgraduates and researchers in the field of vision research and neuroscience.
