Sphere fitting

Michael Doube
Hi all

A colleague just handed me a difficult-looking and user-unfriendly bunch
of MATLAB code that does least-squares sphere fitting to a set of
(x,y,z) coordinates (n ~ 10 usually).

Has anyone implemented something like this for ImageJ?  I'm imagining a
plugin where you click on a bunch of points in a stack, hit go and then
have a centre and radius returned.

The most useful thing I've found so far is this:

cheers,

Mike
