  I recently got the book "Digital Image Processing: A Systems Approach".  I
need to be able to do rubber sheeting but I can't figure out how to set up the
matrices based on the tiepoints.  I understand what the spatial and intensity
interpolations are trying to do, but just don't know what I'm supposed to put
in the equations.  Anybody care to enlighten me?
