Example Usage:

import airlab as al
import SimpleITK as sitk

# ... registration process with image pyramid
constant_flow = transformation.get_flow()
trans = al.transformation.utils.get_displacement_itk(constant_flow, mov_im_level.itk())
warped = sitk.Resample(moving, fixed, trans, sitk.sitkLinear)
