Hi Remi,

I have an Insight Journal paper which proposes an implementation of a
Demons deformable registration optimizing mutual information. You can
get the code and the paper here :

        http://insight-journal.org/dspace/handle/1926/183


I would be glad to help if you have any questions.



Best regards,



Mathieu.
