Detailed Description

Float AOS Barash filter.

Purpose:        Fast Computation of TV recursive flow.
                        Use the Thomas LU model.
                        Semi-Implicit solver using AOS additive splitting

            (I - tau/(1+tau*lambda) * A) * uNew=  (uOld + tau*lambda*u0)/(1.0 + tau*lambda)

                        Should be better than LOD: Rotation invariant.

                        LOD is sequential (handelling each direction x y z in sequence)

                        AOS is parallel (handelling each direction x y z at the same time)
                        AOS build an average operator

                        Both LOD and AOS are designed for large image restoration, O(N) in time ang space!!!
