"
Well,
to say the brain is a computer is correct but misleading. It's
really a highly specialized information-processing device-or
rather, a whole lot of them. Viewing our brains as
information-processing devices is not demeaning and does not
negate human values. If anything, it tends to support them and may
in the end help us to understand what from an
information-processing view human values actually are, why they
have selective value, and how they are knitted into the capacity
for social mores and organization with which our genes have
endowed us."
"Trying to understand
vision by studying only neurons is like trying to understand
bird flight by studying only feathers: it just cannot be done."
-- David Marr in his book
Vision (W.H. Freeman, 1982)
Image
semantics, therefore, must be seen as a property of a human observer
that watches and scrutinizes an image. That is why we can definitely
say: semantics is assigned to an image by a human observer.
-- Emanuel
Diamant in Chapter 5 of the book "Frontiers in
Brain, Vision and AI",2008
