#include <itkVariationalRegistrationNCCFunction.h>
This class computes NCC forces in the variational registration framework.
This class implements NCC forces as given in Hermosillo, Chefd'Hotel, and Faugeras. "Variational methods for multimodal image matching." IJCV 50(3), 2002: 329-343 and Avants et al. "Symmetric diffeomorphic image registration with cross-correlation: evaluating automated labeling of elderly and neurodegenerative brain." Medical image analysis 12(1), 2008: 26-41 (except Jacobian term). We define the derivative of NCC between two images as:
is the step size and is the mean squared spacing. Use SetRadius() (see FiniteDifferenceFunction) to set the size of the neighbourhood to compute local mean values and and the local sums. Alternative, the classical gradient can be replaced by or .
