We  did some work  at Mitre  Corp  [1] on  cloud recognition, which we
presented at the INNC conference  in Paris.   My  own part of the work
involved  mostly the Boundary  Contour System / Feature Contour System
(BCS/FCS) of Grossberg and Mingolla,  which  is a neural  vision model
that   performs a  variety  of  image   enhancement   and  recognition
functions, and which  we used as   a front-end  for a  backpropagation
network to classify  different  cloud  types, as identified   (for the
training set) by meterological specialists.

If you would like more details on the BCS, or my extension  to  it the
MRBCS, I would be happy to send you  a  an informal description I have
prepared as an ASCII file.  If you  are interested in the backprop end
of it,  or the overall  research effort, write to ira at linus.mitre.org,
or howells at linus.mitre.org for further information.
