ELIMINATING IMPULSIVE DISTURBANCES USING ADAPTED WEIGHTED MEDIANS

Janusz Sawicki

Abstract

The idea of adaptive weighted median filtering of disturbed signals is presented in the contribution. The disturbance is assumed to be impulsive, hence linear filters are not a suitable tool for elimination of such pulses. After a short review of literature concerning weighted medians and their properties a piecewise linear process is analyzed and optimum weight vectors of the median filter are determined.
