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.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Get the threshold below which the absolute difference of intensity yields a match. When the intensities match between a moving and fixed image pixel, the update vector (for that iteration) will be the zero vector.
