Hi all

I've been working on a Java port of some MATLAB scripts that fit circles
to data.  I originally started it to find a good method to work out
radii of curvature, and it's grown (since Monday) to be something that
might be useful to other people.

The algorithms are described in detail by Nikolai Chernov on his page,
http://www.math.uab.edu/~chernov/cl/MATLABcircle.html

It includes Chernov's Hyper non-biased algebraic (non iterative, fast
and accurate) circle fitting method and a couple of the geometric methods.

The class is designed to be generic, and I've written an example testing
plugin, here: http://doube.org/files/Test_Circle.java

If you'd like to check it out, I've posted an initial, mostly-working
version at http://doube.org/files/FitCircle.java

It's also in my git repo, http://github.com/mdoube/BoneJ/tree/master.

Cheers,

Mike
