Abstract
The success of ringing artifact reduction in image restoration depends mainly on how restoration methods accommodate the piecewise smoothnes s of the image. This letter presents a regularization method that adap ts both its degree and orientation of regularization operation to the spatial activities of image intensity and edge orientations. This is a chieved by anisotropic diffusion. Its restoration quality compares fav orably with that of a previously proposed regularization method that i s space adaptive only in the degree of regularization.
