Detailed Description

template<class TFixedImage, class TMovingImage, class TDisplacementField>
class itk::VariationalRegistrationDemonsFunction< TFixedImage, TMovingImage, TDisplacementField >

This class computes different Demon forces in the variational registration framework.

This class implements active, passive and symmetric Demons forces given by

\[ f^{active}(x)=\tau\frac{(F(x)-M(x+u(x)))}{\|\nabla M(x+u(x))\|^2 + \kappa|F(x)-M(x+u(x))|^2}\nabla M(x+u(x)) \]

\[ f^{passive}(x)=\tau\frac{(F(x)-M(x+u(x)))}{\|\nabla F(x)\|^2 + \kappa|F(x)-M(x+u(x))|^2}\nabla F(x) \]

\[ f^{symmetric}(x)=\tau\frac{(F(x)-M(x+u(x)))}{\|\frac{\nabla F(x) + \nabla M(x+u(x))}{2}\|^2 + \kappa|F(x)-M(x+u(x))|^2}\frac{\nabla F(x) + \nabla M(x+u(x))}{2} \]

with $\tau$ as the step size and $\kappa$ as the mean squared spacing.
