Detailed Description

template<typename TInputImage>
class itk::WarpHarmonicEnergyCalculator< TInputImage >

Compute the harmonic energy of a deformation field.

This class computes the harmonic energy of a deformation field which is a measure inversely related to the smoothness of the deformation field.
