classdef Median< dsp.private.MedianBase %Median Median values % HMDN = vision.Median returns a System object, HMDN, that computes the % median of the input or a sequence of inputs. % % HMDN = vision.Median('PropertyName',PropertyValue, ...) returns a % median System object, HMDN, with each specified property set to the % specified value. % % Step method syntax: % % Y = step(HMDN, X) computes median of input X. % % System objects may be called directly like a function instead of using % the step method.
