Adaptive weighted meridian nonlinear filter used for filtering of signal with impulsive noise

Popis výsledku v původním jazyce

The median, weighted median, myriad and weighted myriad filters have recently been proposed as a class of nonlinear filters for robust non-Gaussian signal processing in impulsive noise environments. A broad range of statistical processes is characterizedby the generalized Gaussian statistics. For instance, the Gaussian and Laplacian probability density functions are special cases of generalized Gaussian statistics. Moreover, the linear and median filtering structures are statistically related to the maximum likelihood estimates of location under Gaussian and Laplacian statistics, respectively. Recently proposed myriad filtering is based on the maximum likelihood estimate of location under Cauchy statistics. An analogous relationship is formed here forthe Laplacian statistics, as the ratio of Laplacian statistics yields the distribution referred here to as the Meridian. Therefore, the Meridian distribution is also a member of the generalized Cauchy family. Based on the maximum likelih
