Image restoration, rotating filters, edge detection, anisotropic diffusion. In this paper, we present a rotating filter (inspired by (Montesinos and Magnier, 2010), (Magnier et al., 2011c) and (Magnier et al., 2011b)) able to detect homogenous regions and edges regions, even in highly noisy images. Then, we present an anisotropic edge detector which defines two directions for pixels belonging to edges. Finally, we introduce a method for anisotropic diffusion which controls accurately the diffusion near edge and corner points and diffuses isotropically inside noisy homogeneous regions. In particular, our detector provides two different directions on edge and corner points, these informahal-00807974,
