[Insight-users] How to use itkFastSymmetricForcesDemonsRegistrationFunction

[Siwei Yang]

Hi every one,
does anybody know, how to use the registrtation method 
itk::FastSymmetricForcesDemonsRegistionFunction?  It looks like to need 
a itk::FastSymmetricForcesDemonsRegistionFilter. I don't know, if this 
filter has been already implemented.
However, I tried to use itk::SymmetricForcesDemonsRegistionFilter with  
little modification, but the result was very bad.

best wishes
