Median filters: Analysis for 2 dimensional recursively filtered signals
Gonzalo R. Arce, Regis J. Crinon · 2005
Median filtering is a nonlinear technique for smoothing signals. In this paper we find the output distribution of recursively median filtered two dimensional signals with additive impulsive noise. We study the edge jitter effect that recursive median filtering introduces. Finally some examples are included illustrating these results.
