Examples are presented where the even-length median filter offers improved mean squared error characteristics over the odd-length median. This indicates that even-length filters should be considered in optimal filter design. In terms of the mean absolute error criterion, it is shown that the even-length median filter admits a representation as a generalised stack filter.
