Multichannel distance filter
Michail Angelos Pappas, Ioannis Pitas · IEEE Transactions on Signal Processing · 1999
A nonlinear multichannel digital filter is presented in this correspondence. The output is a weighted sum of all samples in the filter window, with a single parameter controlling the filter nonlinearity. Although input data ordering is not required, performance can surpass the performance of other ordering-based multichannel filters.
