Detailed Description

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

Deformably register two images using a PDE algorithm.

PDEDeformableRegistrationFilter is a base case for filter implementing a PDE deformable algorithm that register two images by computing the displacement field which will map a moving image onto a fixed image.

A displacement field is represented as a image whose pixel type is some vector type with at least N elements, where N is the dimension of the fixed image. The vector type must support element access via operator []. It is assumed that the vector elements behave like floating point scalars.

This class is templated over the fixed image type, moving image type and the displacement Field type.

The input fixed and moving images are set via methods SetFixedImage and SetMovingImage respectively. An initial displacement field maybe set via SetInitialDisplacementField or SetInput. If no initial field is set, a zero field is used as the initial condition.

The output displacement field can be obtained via methods GetOutput or GetDisplacementField.

The PDE algorithm is run for a user defined number of iterations. Typically the PDE algorithm requires period Gaussian smoothing of the displacement field to enforce an elastic-like condition. The amount of smoothing is governed by a set of user defined standard deviations (one for each dimension).

In terms of memory, this filter keeps two internal buffers: one for storing the intermediate updates to the field and one for double-buffering when smoothing the displacement field. Both buffers are the same type and size as the output displacement field.

This class make use of the finite difference solver hierarchy. Update for each iteration is computed using a PDEDeformableRegistrationFunction.

Warning: This filter assumes that the fixed image type, moving image type and displacement field type all have the same number of dimensions.

◆ CopyInputToOutput()

template<typename TFixedImage , typename TMovingImage , typename TDisplacementField >

void itk::PDEDeformableRegistrationFilter< TFixedImage, TMovingImage, TDisplacementField >::CopyInputToOutput ( )

overrideprotectedvirtual

Copy the data from the input to the output.

When the input is not set, the output is filled with zero values.

Implements itk::FiniteDifferenceImageFilter< TDisplacementField, TDisplacementField >.

◆ GenerateInputRequestedRegion()

template<typename TFixedImage , typename TMovingImage , typename TDisplacementField >

void itk::PDEDeformableRegistrationFilter< 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 displacement field, the input requested region set to be the same as that of the output requested region.

Reimplemented from itk::ProcessObject.

Reimplemented in itk::GPUFiniteDifferenceImageFilter< TDisplacementField, TDisplacementField, itk::DemonsRegistrationFilter< TFixedImage, TMovingImage, TDisplacementField > >, itk::GPUFiniteDifferenceImageFilter< TDisplacementField, TDisplacementField, PDEDeformableRegistrationFilter< TFixedImage, TMovingImage, TDisplacementField > >, itk::GPUPDEDeformableRegistrationFilter< TFixedImage, TMovingImage, TDisplacementField, TParentImageFilter >, and itk::GPUPDEDeformableRegistrationFilter< TFixedImage, TMovingImage, TDisplacementField, itk::DemonsRegistrationFilter< TFixedImage, TMovingImage, TDisplacementField > >.
