#include <FDistanceAosOp.hpp>
Inheritance diagram for FDistanceAosOp:
Purpose: Fast Computation of Simple AOS recursive flow. Use the Thomas LU model. Semi-Implicit solver using AOS additive splitting (I - tau * A) * uNew= uOld 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!!!
