[Insight-users] Problems with calling ReinitializeLevelSetImageFilter in order to reinitialize narrow band in NarrowBandLevelSetImageFilter

[Amardeep Singh]

Hi there

Well, I changed the definition of the LevelSetNode class to be a child 
of the BandNode class.
Then, I templated the narrow band in itkNarrowBandImageFilterBase to 
consist of LevelSetNode nodes (instead of BandNode nodes). The 
inheritance in the first place was necessary, because the 
ReinitializeImageFilter routines are written with a BandNode node in 
mind. Like this, I can at least get it to compile (I will still have to 
see if it works or not.).
However, I have the strong impression that this is a hack that will lead 
to problems some time in the future.
Does anyone know if there is a specific reason for the division between 
LevelSetNode nodes and BandNode  nodes?
Thanks a lot!

Best regards
Amardeep
