In 1961, Barlow wrote a seminal article where he asked what the computational aims of the visual system are. He concluded that one of the main aims of visual processing is the reduction of redundancy, which has been extended to the efficient coding hypothesis.[4] While the brightnesses of neighbouring points in images are usually very similar, the retina reduces this redundancy. His work thus was central to the field of statistics of natural scenes that relates the statistics of images of real world scenes to the properties of the nervous system.[citation needed]
Barlow also worked in the field of
