Detailed Description

template<typename TFixedImage, typename TMovingImage, typename 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.

Note: This class was developed with funding from the German Research Foundation (DFG: EH 224/3-1 and HA 235/9-1).
