Detailed Description

template<typename TFixedImage, typename TMovingImage, typename TDisplacementField, typename TParentImageFilter = itk::DemonsRegistrationFilter< TFixedImage, TMovingImage, TDisplacementField >>
class itk::GPUDemonsRegistrationFilter< TFixedImage, TMovingImage, TDisplacementField, TParentImageFilter >

Deformably register two images using the demons algorithm with GPU.

GPUDemonsRegistrationFilter implements the demons deformable algorithm that register two images by computing the deformation field which will map a moving image onto a fixed image.

A deformation 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 deformation field type.

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

The algorithm has one parameters: the number of iteration to be performed.

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

This class make use of the finite difference solver hierarchy. Update for each iteration is computed in GPUDemonsRegistrationFunction.

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