[Insight-users] FW: FloodFilledFunctionConditionalConstIterator neighborhood

[Luis Ibanez]

Hi Hauke,

Yes the FloodFilledFunctionConditionalConstIterator uses 4-connectivity
when used in 2D images, and, in general, it uses face-connectivity in
N-D images.

If you wanted to modify this behavior, the key place in the code is
in lines 175-178 of


   Insight/Code/Common/
      itkFloodFilledFunctionConditionalConstIterator.txx


It is suggested the code, that the existing for loop could be replaced
with a ShapeNeighborhoodIteration, in order to provide flexibility
in the connectivity.


     That will make an interesting course project,
     and...
     a nice paper for the Insight Journal   :-)



   Regards,


     Luis
