Detailed Description

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

Flexible framework for deformable registration of two images using PDE-based variational registration.

VariationalRegistrationFilter aims to minimize the functional

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

with $\phi(x)=x+u(x)$ by solving the associated Euler-Lagrange equation (ELE)

$f(x, u(x)) + \alpha A[u](x)=0,\quad x\in\Omega$

$ f $ denotes the force term corresponding to the similarity measure $ D$ and $ A$ is a linear differential operator associated with the regularization term $ S $ . The ELE is solved using gradient descent with a semi-implicite update scheme and step size $\tau$ :

$(2)\quad u^{k+1} = (Id - \tau\alpha A)^{-1}(u^k + \tau f^k).$

VariationalRegistrationFilter has two images as input (fixed image $ R $ , and moving image $ T $ ) and computes the displacement field $ u $ as output.

The force term $ f $ is implemented in a subclass of VariationalRegistrationFunction. The computation of the regularization with $(Id - \tau A)^{-1}$ is implemented in a subclass of VariationalRegistrationRegularizer. Different force terms and regularization methods can be combined by using the methods SetDifferenceFunction() and SetRegularizer().

The implemented method can be summariced as follows:

initialize (default )
do
- compute the update field using and the warped image
- compute the next displacement field by $u^{k+1} = (Id - \tau A)^{-1}(u^k + \tau f^k)$
until is fulfilled or

$ StopCriterion$ is implemented in the class VariationalRegistrationStopCriterion. Use AddObserver() to enable different types of stop criteria in the variational registration framework.

VariationalRegistrationFilter has the following parameters:

fixed image
moving image
force term to compute the update field (see VariationalRegistrationFunction)
regularizer (see VariationalRegistrationRegularizer)
maximum number of iterations
Initial displacement (optional)
mask image to restrict force computation (optional)

This class make use of the finite difference solver hierarchy.

virtual void itk::VariationalRegistrationFilter< TFixedImage, TMovingImage, TDisplacementField >::GenerateInputRequestedRegion ( )

overrideprotectedvirtual

It is difficult to compute in advance the input moving image region required to compute the requested output region. Thus the safest thing to do is to request for the whole moving image.

For the fixed image and deformation field, the input requested region set to be the same as that of the output requested region.
