Paper Abstract

Median-based filtering techniques are compared by considering a test image which contains a central disk-shaped region with a step or a ramp edge against a uniform background. Free parameters are the amplitude of Gaussian noise added,'the edge slope, and the number of filtering iterations. The quantitative comparison measure is the normalized squared error between the filtered noisy image and the noise-free image, on the flat image regions and on the transition region separately.
