[Insight-users] Split based on Shape

[Luis Ibanez]

Hi Srivalli,

Thanks for posting your images,
It is now much clearer what you intended to do.
We were quite off with the assumption that you
were spliting clusters in a parametric space...



We probably don't have in ITK an algorithm that
implements this splitting.

However, if you are willing to give it a try,
the classes recently added by John Galeotti
may be the best way to go. These classes
are intended to represent closed/open paths
in images.

Starting from a representation of your contours
as itk::Paths you could test for left/right turns
in order to identify the places where the figure
must be split.

You may want to take a look at the classes:
