[vtkusers] Filling in blood vessels

[David Gobbi]

Hi Gib,

I have a VTK filter that does thresholded flood-filling, it would do a
little better than thresholding by itself:
http://github.com/dgobbi/VTK/blob/5df7a182240c/Imaging/vtkImageFloodFill.h
http://github.com/dgobbi/VTK/blob/5df7a182240c/Imaging/vtkImageFloodFill.cxx
http://github.com/dgobbi/VTK/blob/5df7a182/Imaging/Testing/Tcl/TestFloodFill.tcl
But I'd have to agree with Mauro that vessel segmentation might be tough
with VTK alone.
