Hi,

I've contributed some code both for the grayscale and the binary case.  
The grayscale version is based on max trees - I've called them  
component trees. Both are usable (and used) now, but the one for the  
grayscale case still lacks some doc.
You can get it from the insight journal or from the main repository to  
get the last improvements/fixes.

Binary case:

   http://www.insight-journal.org/browse/publication/176
   http://voxel.jouy.inra.fr/darcs/contrib-itk/ 
binaryAttributeMorphology/

Grayscale case:

   http://www.insight-journal.org/browse/publication/210
   http://voxel.jouy.inra.fr/darcs/contrib-itk/componentTree/

Any comments or improvements are welcome!

Regards,

Gaëtan
