#include <itkESMDemonsRegistrationFunction.h>
Fast implementation of the symmetric demons registration force.
This class provides a substantially faster implementation of the symmetric demons registration force. Speed is improved by keeping a deformed copy of the moving image for gradient evaluation.
Symmetric forces simply means using the mean of the gradient of the fixed image and the gradient of the warped moving image.
Note that this class also enables the use of fixed, mapped moving and warped moving images forces by using a call to SetUseGradientType
The moving image should not be saturated. We indeed use NumericTraits<MovingPixelType>::Max() as a special value.
This implementation was taken from the Insight Journal paper: http://hdl.handle.net/1926/510
