when solving ill-posed inverse problems in order to handle the stabilitiy issue. A way to achieve such a regularization is to consider constrained optimization problems as proposed in the Tikhonov-Philips [...] in the direction of gradients with high values. Various choices of isotropic diffusion equations, such as Perona-Malik, were successfully proposed in the literature. In the case of Perona-Malik, a sup
