One could just as well say that the motion search is a way of
finding a reasonable starting point for the optimization.)

+The dense inverse search paper [Kroeger16] sets
up the energy terms as described by some motion tensors and normalizations,
then says simply that it is optimized by “θ_vo fixed point iterations
and θ_vi iterations of Successive Over Relaxation (SOR) for the linear
