In this paper, we have proposed a new type of filter which has the most desirable properties of an image smoothing filter. These properties are 1) robust smoothing efficiency, 2) edge preservation, and 3) thin-line detail preservation. The new filter computes its output as the median of weighted averages, instead of plain averages as used in the Hodges-Lehman D-filter, of symmetrically placed order statistics. One particular weighting scheme is considered in details for experiments. The experimental and comparison results are included verifying the useful properties of the proposed filter.
