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