This paper introduces a new image processing algorithm, called the pseudomedian filter, which is based on concepts of morphological image processing. The pseudomedian filter possesses many of the properties of the median filter, but it can be computed much more efficiently. Introduction The median filter has found significant application in the processing of multidimensional signals for noise reduction and signal enhancement [1 -3]. The principal drawback of median filtering is its…

It is shown how linear combinations of morphological operators can be formed to alleviate the bias introduced by the individual morphological operators. Since every morphological operator has a

Pseudo-median filter with enhancing impulse suppression

The improved pseudo-median filter algorithm with impulsive noise detecting and suppressing enhances the ability of impulse-attenuation and is a higher efficient alternative to median filter for the application in wireless sensor network.

Negative Weighted Repeated Pseudo-median Filter

In this paper, the Negative Weighted Repeated Pseudo-median Filter (NWRPM), a new method combined the characteristics of repeated median filter (RM), weighted median filter and pseudo-median filter

Experimental results show that the proposed adaptive variable block-based method gives a satisfactory result in terms of noise level and block size.

Continuous-time analysis of the response of the pseudomedian and related filters to periodic signals

A continuous time method is introduced to analyze the response of median, pseudomedian, average (mean), and midrange filters to certain periodic signals. The filter definitions are generalized to
