    Actually, based on this report, 
http://reports-archive.adm.cs.cmu.edu/anon/ml/CMU-ML-06-118.pdf, it 
appears like HAMMER operates on par with Demons.  The authors concluded 
that their hybrid FEM/Demons method worked slightly better using their 
metrics.  In short, not having HAMMER in ITK is probably not a big loss 
for ITK.  Also, after using HAMMER for a year or so, and implementing 
some badly needed features on my own in order to use it, I also agree 
with Bill's comment. 
    To comment on segmented vs. intensity based registration ... I would 
be interested to see a comparison of segmented vs. intensity based 
registration using B-splines or Demons.  Has anyone tried this yet?
