I think in astronomical / biological circles this kind or problem is known as "blob analysis", or something like that (certainly I remember the word "blob" correctly ;-). Try one of the numpy / numarray / Numerical Python / SciPy lists, bound to be people there who know a lot about this sort of problem, and your problem sounds quite a bit easier than the general one.
