#include <IF2DRestorationOp.hpp>
Inheritance diagram for IF2DRestorationOp:
Purpose: Fast Computation of gaussian blurring.
Very useful for linear time scale space, Retinex, and linear time image blurrings.
Much faster than FFT on large kernels: sigma >>> 0
Semi-Implicit solver using LOD multiplicative splitting
(I - tau * A) * uNew= uOld
