Detailed Description

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

This class encapsulate the PDE which drives the demons registration algorithm. It is used by DemonsRegistrationFilter to compute the output deformation field which will map a moving image onto a a fixed image.

Non-integer moving image values are obtained by using interpolation. The default interpolator is of type LinearInterpolateImageFunction. The user may set other interpolators via method SetMovingImageInterpolator. Note that the input interpolator must derive from baseclass InterpolateImageFunction.

This class is templated over the fixed image type, moving image type, and the deformation field type.

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