[lug] Off-topic: Contour line in image problem

[Rob Mohr]

Approximate or match profile to a curve function.  Then integrate to calc
the area.  I would *guess* that cad programs such as AutoCad use a series
of Laplace Transforms to do the same thing.  

Save for the challenge, and dusty math books, you can prolly get something
via a perl library and a good Google search string.
