ELIMINATING IMPULSIVE DISTURBANCES USING ADAPTED WEIGHTED MEDIANS

• 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.
