The ANTs guys originally claim their "multiply by negative scaling factor" is to calculate a small-scale linear approximation of the inverse average transform.

InverseDisplacementFieldImageFilter, InvertDisplacementFieldImageFilter and IterativeInverseDisplacementFieldImageFilter

all can estimate a inverse of a displacement field transform. Can this achieve better/faster convergence?
