Detailed Description

template<typename TParametersValueType, unsigned int VDimension>
class itk::GaussianExponentialDiffeomorphicTransform< TParametersValueType, VDimension >

Exponential transform using a Gaussian smoothing kernel.

Exponential transform inspired by the work of J. Ashburner (see reference below). Assuming a constant velocity field, the transform takes as input the update field at time point t = 1, \(u\) and smooths it using Gaussian smoothing, \(S_{update}\) defined by GaussianSmoothingVarianceForTheUpdateField We add that the current estimate of the velocity field and then perform a second smoothing step such that the new velocity field is

\begin{eqnarray*} v_{new} = S_{velocity}( v_{old} + S_{update}( u ) ). \end{eqnarray*}

We then exponentiate \(v_{new}\) using the class ExponentialDisplacementImageFilter to yield both the forward and inverse displacement fields.
