Detailed Description

template<class TScalar, unsigned int NDimensions>
class itk::BSplineSmoothingOnUpdateDisplacementFieldTransform< TScalar, NDimensions >

Representation of a smooth deformation field with B-splines.

Although there already exists a B-spline transform in ITK which can be used for processes such as image registration, if these processes involve a dense sampling of an image a significant computational speed-up can be achieved by densely sampling the B-spline transform prior to invoking transformations.

This class takes as input a displacement field, smooths it on demand using the specified B-spline parameters. This represents an alternative approach to B-spline (FFD) registration and is explained more in detail in the reference given below.
