Thomas,
The plugin measures arc length. I read your question too fast. Measuring curvature sounds interesting and I think the plugin could be modified to do it, but I don't know if that is the easiest way to a solution.

Thank you Bob,
I looked at the description and could not find what I am aiming for.
If after thresholding the object is perfectly circular, the result should
be a constant value versus the pixels along the outline. If the object is
bumpy, the function would not be constant any more. If part of the outline
is concave the function would be negative there.
Are you sure the plugin you mentioned does that?
Best, Thomas
