[Insight-users] Degenerated volumes question

[Benjamin King]

Hi all,

I'm working on a program that takes a labled volume and then finds the 
minimal itk::Region that contains all voxels with a certain label. I often 
get very small regions i.e. with a size of (1,8,4). Extracting them with 
itk::RegionOfInterestImageFilter and afterwards applying morphological 
operations often (but not always) results in segmentation faults.

Padding the small regions will probably fix this but I was wondering if it 
would be possible to hide this in the MorphologyImageFilter class. After 
all these filters have to handle boundary conditions anyway, haven't they?

I also think that a segmentation fault is not a very graceful way to handle 
degenerated volumes.


Best regards,
  Benjamin
