#include <itkSymmetricForcesDemonsRegistrationFilter.h>
Deformably register two images using the demons algorithm.
This class was contributed by Corinne Mattmann, ETH Zurich, Switzerland. based on a variation of the DemonsRegistrationFilter. The basic modification is to use equation (5) from Thirion's paper along with the modification for avoiding large deformations when gradients have small values.
SymmetricForcesDemonsRegistrationFilter 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 DemonsRegistrationFunction.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Get the metric value. The metric value is the mean square difference in intensity between the fixed image and transforming moving image computed over the the overlapping region between the two images. This value is calculated for the current iteration

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Set/Get the threshold below which the absolute difference of intensity yields a match. When the intensities match between a moving and fixed image pixel, the update vector (for that iteration) will be the zero vector. Default is 0.001.
