Paper Abstract

In this paper, we present the output probability density functions of generalized open-closing (GOC) and generalized close-opening (GCO) filters under the different input distributions such as uniform, Gaussian and biexponential distributions, and calculate their digital features (expectations and variances). Then, we apply these filters to restore an image corrupted by impulsive noise and further test their efficiency in noise-suppressing and detail- preserving characteristics. The simulation results show that the GOC and GCO filter have good performances.
