Abstract
We propose a two-pass median filter for impulse noise suppression in color images. The first pass is our previously presented algorithm, PNN-VMF. The second pass routine is chosen dynamically on the basis of the number of pixel modifications performed by the first pass filtering. Such an approach is likely to avoid barm (blurring edges etc.) due to excessive filtering. The effectiveness of the algorithm has been experimentally verified.
