Ph. Dietz et Lr. Carley, SIMPLE NETWORKS FOR PIXEL PLANE MEDIAN FILTERING, IEEE transactions on circuits and systems. 2, Analog and digital signal processing, 40(12), 1993, pp. 799-801
In this work, we present networks that estimate the median of an odd n
umber of inputs. The simplicity of these circuits rivals that of resis
tive grids, allowing their use in pixel plane processing systems.
