Hi,
It looks like Nils wants to segment the pelvis from CT and MR.
This should be do-able with itk now...
1) Region grow (itkRegionGrowImageFilter or
itkFuzzyConnectednessImageFilter.h)
2) morphological erosion (2cm - remove ribs)
3) morphological dilate (3cm - restore to original size + fill in marrow
holes)
4) morphological erosion (1cm - restore to original size)
The problem with abdominal MR are the intensity inhomogeneities.
Try the MRBiasFieldCorrection method and then do the above for MR (bones
being dark).
Stephen
