Abstract :
Studies the speed of operation of median filtering algorithms. An iterative approach is investigated, and then simplified to take the local neighbourhood centre pixel as a starting approximation. Overall speedup factors of 2-4 are obtained. The method is useful when the ´running median´ technique cannot be used, as for ´skimmed´ median-based corner detectors.
