Abstract
A class of nonlinear two-dimensional filters is presented. A matrix description is developed for such operators, and some symmetry conditions are imposed which simplify and render more effective the filter structure. A strategy for the design of filters capable of enhancing images having reduced contrast and degraded by noise is proposed
