Rank-order based filters such as stack filters, multistage median filters, morphological filters, and order statistic filters, have all proven to be very effective at enhancing and restoring images. Perhaps the primary reason for their success is that they can suppress noise without destroying important image details such as edges and lines. Two approaches have been used in the past to design rank-order based nonlinear filters to enhance or restore images. They may be called the structural… CONTINUE READING
