Biological Vision
There are interesting relations between scale-space representation and biological vision. Neurophysiological studies have shown that there are receptive field profiles in the mammalian retina and visual cortex, which can be well modelled by linear Gaussian derivative operators, in some cases also complemented by a non-isotropic affine scale-space model and/or non-linear combinations of such linear operators.

Famous quotes containing the words biological and/or vision:
“In America every woman has her set of girl-friends; some are cousins, the rest are gained at school. These form a permanent committee who sit on each other’s affairs, who “come out” together, marry and divorce together, and who end as those groups of bustling, heartless well-informed club-women who govern society. Against them the Couple of Ehepaar is helpless and Man in their eyes but a biological interlude.”
—Cyril Connolly (1903–1974)
“Thinking is seeing.... Every human science is based on deduction, which is a slow process of seeing by which we work up from the effect to the cause; or, in a wider sense, all poetry like every work of art proceeds from a swift vision of things.”
—Honoré De Balzac (1799–1850)
