Detailed Description

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

Deformably register two images using the demons algorithm.

DemonsRegistrationFilter implements the demons 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 algorithm has one parameters: the number of iteration to be performed.

The output displacement 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 DemonsRegistrationFunction.

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

PushBackInput(), PushFronInput() in the public section force the input to be the type expected by an ImageToImageFilter. However, these methods end of "hiding" the versions from the superclass (ProcessObject) whose arguments are DataObjects. Here, we re-expose the versions from ProcessObject to avoid warnings about hiding methods from the superclass.
