A generalization of the linear fractional integral equation u(t)=u"0+@?^-^@aAu(t), 1 0, and allows us to handle the diffusion by means of a viscosity parameter instead of introducing nonlinearities in the equation as in the Perona-Malik and alike approaches. Several experiments showing the improvements achieved by our approach are provided.
