153–175 Application of the Topological Gradient Method to Color Image Restoration∗ Didier Auroux†, Lamia Jaafar Belaid‡, and Badreddine Rjaibi‡ Abstract

In order to check this prediction, a comparison with exact solutions of the cylindrical bending of the lattice is performed in Section 4. It reveals that only the

The problem here consists in extracting the cleavage facets from a fractured surface in steel (MEB image).. A rather complex combination of contrast and distance functions is used

• a discrete space of unknowns X D , which is a finite dimensional space of discrete unknowns – e.g., the values at the nodes of a mesh (as in the conforming P 1 finite element

We apply Scheme (21) with three different gradient discretisations, corresponding respectively to the mass- lumped conforming P 1 finite element method (or CVFE method, see [18] for

The diffusion tensor used to restore an image is anisotropic on the edges, with a small diffusion coefficient on primary edges and a larger one on the secondary edges.. This

Abstract: We prove in this paper the second-order super-convergence in L ∞ -norm of the gradient for the Shortley-Weller method. Indeed, this method is known to be second-order
