In Heinonen and Neuvo (1988), the FIR-median hybrid (FMH) filter, a class of median type filters for image processing was proposed. In these filters, linear FIR predictors are used in conjunction with the median operation. In the present paper, the one dimensional FMH is shown to be biased at boundaries and does not smooth junctions well for one dimensional signals. In addition it does not preserve corners of less than 900 or line endings for two dimensional signal. The residual technique introduced can solve both of these problems.<>
