A New Adaptive Multistage Median Filter

A new filter structure called adaptive multistage median filter (say AMM for simple) is proposed. It follows the basic architecture of the multistage median filter (MLM), but its subfilters are based on the date-dependent and sizes variant subwindows, that allows AMM give better performance than MLM. In addition, like MLM, the proposed filter is not only computationally effective, but also needs no a priori information about image or noise. Experiment results are given to show the superiority of the new proposed filters.
