Hi,
It gets rid of overlapping coordinates of the ROI that do not contribute to
the actual shown shape. If you run consecutively the macro several times you
end up with lots of repeated ROI points in the ROI chain that do not make a
difference to the ROI that you see. The code gets rid of those.
If there are no overlapping points it uses the original smoothed chain, if
there are, it uses the thinned chain.

Regards

Gabriel
