Abstract :
The authors point out that, in one-dimensional (1-D) recursive median (RM) filtering, all of the previous outputs except the most recent output are redundant in determining the present output. On the basis of this observation, efficient software and VLSI algorithms for 1-D RM filters are presented. It is shown that the implementation of RM filtering based on the proposed algorithms is simpler than that of standard median filtering
