[Insight-users] ImageFunctions in itk::CurvatureRegistrationFilter

[somi]

Hi,
I am trying to use different finite difference functions as listed at
http://www.itk.org/Doxygen/html/group__FiniteDifferenceFunctions.html
in itk::CurvatureRegistrationFilter .

However, itk::CurvatureRegistrationFilter requires a GetMetric() function
which is implemented only in few finite difference functions
(e.g. itk::FastSymmetricForcesDemonsRegistrationFunction ).
Is there any way I could use Mutual Information function
with itk::CurvatureRegistrationFilter ? Do I have to implement a
GetMetric()
in itk::MIRegistrationFunction< TFixedImage, TMovingImage, TDeformationField
> ?

Thanks,
Somi
