Abstract: We are proposing a new filter for image restoration and enhancement tasks that relies
on image orientation analysis techniques for steering and directing smoothing or
enhancement processes. The filter is developed under the Partial Differential Equations
(PDE) framework using asymmetric orientation estimation operators and it has better
junction preservation and noise removal properties than existing classical PDE based
methods. We employ an experimental setup involving several computer generated
images and a statistical interpretation of the results for proving the efficiency of the
method in processing images composed of directional textures and degraded by
additive Gaussian noise. The algorithm is compared also with state–of-the-art non-PDE
based methods in filtering images containing oriented patterns.
