Title: The Perona-Malik paradox

The Perona-Malik equation is  the prototype  of "forward-backward" parabolic equations. It is the formal gradient flow of an integral functional with non -convex integrand. From the analytic point of view one expect that an ill-posed problem. However numerical simulations presents an unexpected stability. This is known in the literature as "Perona-Malik paradox".
