Detailed Description

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

Diffeomorphic deformable registration of two images using static velocity fields.

VariationalDiffeomorphicRegistrationFilter is derived from VariationalRegistrationFilter and aims to minimize the functional

$(1)\quad J( \phi ) = D[R, T\circ\phi] + \alpha S[\phi] \rightarrow \min$

with $\phi(x)=exp(v(x))$ and $ v(x)$ is a static velocity field. Let $ f $ denote the force term corresponding to the similarity measure $ D$ and $ A$ denote the linear differential operator associated with the regularization term $ S $ , VariationalDiffeomorphicRegistrationFilter implements the following iterative scheme to compute $ v$ (and $\phi$ ):

initialize (default ) and $\phi^0=exp(v)$ (default $\phi^0=Id$ )
do
- compute the update field using and the warped image $T\circ\phi^k$
- compute the next velocity field by $v^{k+1} = (Id - \tau\alpha A)^{-1}(v^k + \tau f^k)$
- compute the next transformation $\phi^{k+1}=exp(v^{k+1})$
until is fulfilled or

The force term $ f $ is implemented in a subclass of VariationalRegistrationFunction. The computation of the regularization with $(Id - \tau\alpha A)^{-1}$ is implemented in a subclass of VariationalRegistrationRegularizer. The exponentiation of the velocity field $\phi(x)=exp(v(x))$ is done using the ExponentialDisplacementFieldImageFilter.

You can set SmoothUpdateFieldOn() to smooth the velocity field before exponentiation.
