#include <itkMultiResolutionPDEDeformableRegistration.h>
Framework for performing multi-resolution PDE deformable registration.
MultiResolutionPDEDeformableRegistration provides a generic framework to peform multi-resolution deformable registration.
At each resolution level a PDEDeformableRegistrationFilter is used to register two images by computing the deformation field which will map a moving image onto a fixed image.
A deformation field is represented as an 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.
The internal PDEDeformationRegistrationFilter can be set using SetRegistrationFilter. By default a DemonsRegistrationFilter is used.
The input fixed and moving images are set via methods SetFixedImage and SetMovingImage respectively. An initial deformation field maybe set via SetInitialDisplacementField if is matches the characteristics of the coarsest pyramid level. If no such assumption can be made (e.g. the deformation field has the same characteristics as the input images), an initial deformation field can still be set via SetArbitraryInitialDisplacementField or SetInput. The filter will then take care of mathching the coarsest level characteristics. If no initial field is set a zero field is used as the initial condition.
MultiResolutionPyramidImageFilters are used to downsample the fixed and moving images. A VectorExpandImageFilter is used to upsample the deformation as we move from a coarse to fine solution.
This class is templated over the fixed image type, the moving image type, and the Deformation Field type.
The current implementation of this class does not support streaming.
