I guys, I have to skeletonize a 3D vascular net of the liver vessels. Any ideas/code/examples that could help me? I know that it exists the class itkBinaryThinningImageFilter but it works only for 2D images…  
Thanks in advance for any help!

Hi Marco,  
the easiest would be to use the `itkBinaryThinningImageFilter3D` from the ITKThickness3D external module: [https://github.com/InsightSoftwareConsortium/ITKThickness3D](https://github.com/InsightSoftwareConsortium/ITKThickness3D)
