[Insight-users] How to get mean shape image instead of vector in itkActiveShapeModelCalculator

[Zachary Pincus]

Aah, I see now; sorry for the misunderstanding!

Perhaps the SpatialObject hierarchy (which you can read about in the 
ITK software guide) would allow you to take a list of the landmark 
points, connect them into a polygon or surface, and then either 
rasterize that to an image, or just use the spatial object as is?
