#include <itkExponentialDeformationFieldImageFilter.h>
Computes a diffeomorphic deformation field as the Lie group exponential of a vector field.
ExponentialDeformationFieldImageFilter takes a 'smooth' vector field as input and computes the deformation field that is its exponential.
Given that both the input and output deformation field are represented as discrete images with pixel type vector, the exponential will be only an estimation and will probably not correspond to a perfect exponential. The precision of the exponential can be improved at the price of increasing the computation time (number of iterations).
The method used for computing the exponential deformation field is an iterative scaling and squaring (cf Arsigny et al., "A Log-Euclidean Framework for Statistics on Diffeomorphisms", MICCAI'06).
This filter expects both the input and output images to be of pixel type Vector.
This implementation was taken from the Insight Journal paper: https://hdl.handle.net/1926/510

If ComputeInverse is on, the filter will compute the exponential of the opposite (minus) of the input vector field. The output deformation fields computed with ComputeInverse set to on and off respectively therefore represent spatial transformations that are inverses of each other.

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.
