Hi Everyone, I am trying to define a polygonal ROI object as part of an initial image segmentation. I looked at the ITK doumentation for itk::Region, itk::ImageRegion, itk::MeshRegion, but they don't seem to provide what I need. Does ITK have a class for simple (planar) polygons? Is there an associated iterator for a plygonal region? Thanks, Ofri Sadowsky.
