Paper Abstract

This paper describes the generalization of the Radix method of finding the median to Weighted Median (WM), Order Statistic (OS) and Weighted Order Statistic (WOS) filters. The method requires that input signal is discretized to 2M possible magnitude levels. Supposing that N is the filter window width the time complexities for different one-dimensional filters are O(M) for Standard Median (SM) filters, 0(NM) for WM filters, O(M) for OS filters and 0(NM) for WOS filters. Comparison of time complexities with other methods is performed.
