%X This paper presents a new adaptive multilevel median filter based on direction information measure to solve the contradiction between noise attenuation and image details-preserving (edge-preserving). Direction is one of nature distinctions between noise and edge, and an adaptive algorithm based on direction information measure is constructed to decide the format and size of median filter without any knowledge of image and noise. A comparison of median filter, single direction multilevel filter, bidkection multilevel filter and the method in this paper has been done. The result indicates that the method has better effectiveness.
