Detailed Description

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

Symmetric diffeomorphic deformable registration of two images using static velocity fields.

VariationalSymmetricDiffeomorphicRegistrationFilter is derived from VariationalRegistrationFilter and aims to minimize the functional

$(1)\quad J( \phi ) = \frac{1}{2} (D[R, T\circ\phi] + D[R\circ\phi^{-1}, T]) + \alpha S[\phi] \rightarrow \min$

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 $ , VariationalSymmetricDiffeomorphicRegistrationFilter implements the following iterative scheme to compute $ v$ (and $\phi$ ):

initialize (default ), $\phi_0=exp(v_0)$ and $\phi_0^{-1}=exp(-v_0)$
do
- compute the forward update field $f_k^{forw}$ using and the warped image $T\circ\phi_k$
- compute the backward update field $f_k^{back}$ using the warped image $R(x)\circ\phi_k^{-1}$ and
- compute the next velocity field by $v_{k+1} = (Id - \tau\alpha A)^{-1} (v_k + \frac{\tau}{2}(f_k^{forw} + f_k^{back}))$
- compute the next transformation $\phi_{k+1}=exp(v_{k+1})$ and the inverse $\phi_{k+1}^{-1}=exp(-v_{k+1})$
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.
