Detailed Description

Abstract Float Regularized AOS flow.

Author:

Bernard De Cuyper

Version:

1.1

Date:

19/01/2004

 
Purpose:        Fast Computation of Regularized AOS 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!!!
