#include <itkLevelSetMotionRegistrationFunction.h>
This class encapsulate the PDE which drives the demons registration algorithm. It is used by LevelSetMotionRegistrationFilter 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.

Set/Get the parameter alpha. Alpha is added to the calculated gradient magnitude prior to normalizing the gradient to protect against numerical instability as the gradient magnitude approaches zero. This should be set as a small fraction of the intensity dynamic range, for instance 0.04%. Default is the absolute (not percentage) value of 0.1.

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.
