[Insight-users] HausdorffDistanceImageFilter

[cecilia.zanella at studio.unibo.it]

Thank you Andinet!!
My purpouse is to calculate the Hausdorff Distance between a synthetic image 
(sphere) and the surface (PolyData) resulting from segmentation, to compare 
different segmentation techniques. Do you know if there is another alternative 
way to catch up the same result? 

Thanks,
Cecilia.
