Aldo W. Morales, Eugene C. Boman, Sung-Jea Ko · IEEE Signal Processing Letters · 2002
Sample and rank selection probabilities are important in the analysis of weighted median filters as well as in comparing linear and nonlinear filters. We propose a new, efficient algorithm to calculate these probabilities for weighted median filters. The computational savings of this new algorithm are substantial and compare favorably with other known algorithms.
