It is shown that in one-dimensional (1-D) recursive median (RM) filtering, the present output is fully determined by the input data in the window and by the most recent output. All other past outputs are shown to be redundant. Based on this result, efficient algorithms and VLSI implementation for 1-D RM filters are presented, and shown to compete favorably with those for standard median (SM) filtering.
