Oddly enough, Karsten Rodenacker was just here for the IEPA
Conference of Mathematical Morphologists and we spent a pleasant
weekend walking in the mountains and talking about this very
thing for a chapter of a book I am writing. As a result, I'm
gung ho to start writing some programs to do just this thing.
If you would like to send me some images, I would be happy
to play around with this a little bit.
I can't guarantee exactly when you will see results (the
holidays seem to slow things down, although I have spent free
Christmas afternoons in the past working on IDL programs,
much to the disgust of my family). But you catch me at
a reasonably good time to work on something like this, if
you are interested.
Cheers,
David
P.S. I think this particular problem would be fairly easy,
looking at the images. But perhaps the article that results
would at least give you some notion of how to approach a
problem like this in the future.
