template<typename TInputImage, typename TOutputImage>
class itk::ExponentialDisplacementFieldImageFilter< TInputImage, TOutputImage >
Computes a diffeomorphic displacement field as the Lie group exponential of a vector field.
ExponentialDisplacementFieldImageFilter takes a 'smooth' vector field as input and computes the displacement field that is its exponential.
Given that both the input and output displacement 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 displacement field is an iterative scaling and squaring (cf Arsigny et al., "A
Log-Euclidean Framework for Statistics on Diffeomorphisms", MICCAI'06).
![\[ exp(\Phi) = exp( \frac{\Phi}{2^N} )^{2^N} \]](form_216.png)
This filter expects both the input and output images to be of pixel type Vector.
