Variational Image Restoration
Variational Convex Potential
Purpose: Variational Restoration uses a reaction diffusion approach,
the reaction term ensures that the evolution is always near the original image.
It is more robust against strong noise that classic diffusion, but do not enhance edges.
ut= div( g(|grad(u)|^2) grad(u)) + beta*(f-u)
g(s2)= 1.0/sqrt(1.0+ s2/contrast*contrast);
Variational Restoration can be used in cascade to do a pyramidal restoration.
