Efficient implementation of one-dimensional recursive median filters
Sung-Jea Ko, Y.H. Lee, Adly T. Fam · IEEE Transactions on Circuits and Systems · 1990
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 are shown to compete favorably with those for standard median (SM) filtering.>
