Abstract
In processing digital images of different physical origin, it is frequently necessary to eliminate from analyzed fragments the spatially uncorrelated additive noise resulting usually from imperfect recording process. Fast algorithms for calculating geometric characteristics of such connected noise regions are proposed and program-implemented. The obtained results were used to construct optimal rank filters intended to detect and suppress the noise.
