Abstract :
This paper derives the joint distribution of medians over moving windows in a two dimensional noisy image. The general formulation presented allows derivation of the probability distribution, needed to evaluate the probability of failing to detect an edge when present (“edge miss probability”) and the probability of falsely detecting a nonexistent edge
