Peter,

Do a paper search on the Cognitron and Neo-Cognitron.  Can't remember the
fellow's name, but the papers are on a neural system that is designed for
recognition of characters...handwritten or otherwise.  I believe the
technique involved the use of defocused images (broaden the input matrix)
and a Kohenen network as a content-addressable or associative memory.
I'm going by very fuzzy memory here and can't find my references right now,
so may be a bit off...but the above is all I had to go by when I looked for
the papers myself.  Found them with no problems.

Brian
