Compute deformation field smoothness

Hello. I am trying to develop and algorithm for deformable image registration and I want to know if there is a way to calculate the smoothness of the deformation field that warps an image.

Thank you in advance

It depends how “smoothness” is defined, but one option is to characterize smoothness with the strain energy density computed from the displacement field strain.
