Detailed Description

template<class TFixedImage, class TMovingImage, class 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 $\frac{\nabla F(x) + \nabla M(x+u(x))}{2}$ .

See Also: VariationalRegistrationFilter; VariationalRegistrationFunction

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