Detailed Description

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

Modifies the UpdateTransformParameters method to peform a Gaussian smoothing of the displacement field after adding the update array.

This class is the same as DisplacementFieldTransform, except for the changes to UpdateTransformParameters. The method smooths the result of the addition of the update array and the displacement field, using a GaussianOperator filter.

To free the memory allocated and cached in GaussianSmoothDisplacementField on demand, see FreeGaussianSmoothingTempField.
