Well, I am using a picture, that isn't super clear (e.g could be
places where the edge isn't closed )
also I think that computing whatever a contour is closed or not is
very time consuming ( correct me if I Am wrong here..)
and I need something that work very fast.
thanks for the idea, if you have more I would be glad to hear.
