[Insight-users] Labeled neighborhoods

[Luis Ibanez]

Hi Daniel,

It seems that you can take advantage of the Voting filters.

http://www.itk.org/Insight/Doxygen/html/classitk_1_1VotingBinaryImageFilter.html

You probably can create your filter by just modifying the
code of the Votingfilter, given that this one already computes
the counts of zero neighors,


    Regards,



        Luis
