Detailed Description

template<typename TFixedImage, typename TMovingImage, typename TDisplacementField>
class itk::VariationalRegistrationSSDFunction< TFixedImage, TMovingImage, TDisplacementField >

This class computes SSD forces in the variational registration framework.

This class implements SSD forces given by

\[ f^{SSD}(x)=\tau\kappa(F(x)-M(x+u(x)))\nabla M(x+u(x)) \]

$\tau$ is the step size and $\kappa$ is the mean squared spacing. Alternative, the classical gradient $\nabla M(x+u(x))$ can be replaced by $\nabla F(x)$ or $\frac{\nabla F(x) + \nabla M(x+u(x))}{2}$.
