Detailed Description

template<class TInputImage, class TOutputImage>
class itk::ExponentialDeformationFieldImageFilter< TInputImage, TOutputImage >

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.
