[vtkusers] Removing surfaces created by a watershed transform

[Roman Grothausmann]

Dear mailing list members,


How can I remove the surfaces created/introduced by a watershed transform?
Would these steps work? :
1. Run watershed separation that does not introduce a border on a binary 
image of some blobs
2. mesh the resulting label image with vtkDiscreteMarchingCubes
3. find and remove congruent triangles

Is my assumption correct that vtkDiscreteMarchingCubes yields congruent 
triangles for surfaces introduced by a border-less watershed separation? 
And is this the case ONLY for the introduced surfaces?
Is there a VTK-filter that would remove congruent triangles? 
vtkCleanPolyData seems to be close to what I would need but not exactly, 
I think.

Any help or hints on this are very much appreciated
Roman
