Detailed Description

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

This class encapsulate the PDE which drives the demons registration algorithm (formula (5) in J.-P. Thirions's paper "Fast Non-Rigid Matching of 3D Medical Images", May 1995). It is used by SymmetricForcesDemonsRegistrationFilter to compute the output displacement field which will map a moving image onto a a fixed image.

This class was contributed by Corinne Mattmann, ETH Zurich, Switzerland. based on a variation of the DemonsRegistrationFunction. The basic modification is to use equation (5) from Thirion's paper along with the modification for avoiding large displacements when gradients have small values.

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 displacement field type.

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