Abstract :
With the aid of the threshold decomposition, rank order filters are shown to be the optimal filters under a general error criterion which includes an absolute error criterion. The particular rank order filter that is optimal is specified by a linear program. The technique developed in this paper extends to an entire class of nonlinear filters known as stack filters [5].
