Detailed Description

template<typename TParametersValueType, unsigned int NDimensions>
class itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, NDimensions >

Exponential transform using B-splines as the 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 a B-spline smoothing (i.e. fitting) operation, $S_{update}$ defined by SplineOrder and NumberOfControlPointsForTheUpdateField. 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.
