Detailed Description

template<typename TFixedImage, typename TMovingImage, typename TOutputTransform = DisplacementFieldTransform<double, TFixedImage::ImageDimension>, typename TVirtualImage = TFixedImage, typename TPointSet = PointSet<unsigned int, TFixedImage::ImageDimension>>
class itk::SyNImageRegistrationMethod< TFixedImage, TMovingImage, TOutputTransform, TVirtualImage, TPointSet >

Interface method for the performing greedy SyN image registration.

For greedy SyN we use m_Transform to map the time-parameterized middle image to the fixed image (and vice versa using m_Transform->GetInverseDisplacementField() ). We employ another ivar, m_InverseTransform, to map the time-parameterized middle image to the moving image.

Output: The output is the updated transform which has been added to the composite transform.

This implementation is based on the source code in Advanced Normalization Tools (ANTs)

Avants, B. B.; Tustison, N. J.; Song, G.; Cook, P. A.; Klein, A. & Gee, J. C. A reproducible evaluation of ANTs similarity metric performance in brain image registration. Neuroimage, Penn Image Computing and Science Laboratory, University of Pennsylvania, 2011, 54, 2033-2044

The original paper discussing the method is here:

Avants, B. B.; Epstein, C. L.; Grossman, M. & Gee, J. C. Symmetric diffeomorphic image registration with cross-correlation: evaluating automated labeling of elderly and neurodegenerative brain. Med Image Anal, Department of Radiology, University of Pennsylvania, 2008, 12, 26-41

The method evolved since that time with crucial contributions from Gang Song and Nick Tustison. Though similar in spirit, this implementation is not identical.
