Order Statistic-Based Nonlinear Filters: Stack Filters and Weighted Median Filters
Edward J. Coyle, Moncef Gabbouj, Ji‐Sang Yoo · 2005
Since the introduction of the median filter by John Tukey in 1971, many important classes of order statistic-based nonlinear filters have been developed. In this paper we review some recent results obtained for the two filter classes known as stack filters and weighted median filters. The highlights include new results on optimal filter design and fast training algorithms.
