Abstract

An adaptive switching median filter (ASMF) is presented in this paper. Extensive simulation shows that it can provide very high quality restored images for images that are contaminated by "salt & pepper" noise, especially when the noise density is large. Comparing with other median filtering methods, the ASMF can effectively remove "salt & pepper" noise even when the majority of pixels in the filtering window are noise pixel or all of the pixels are noise pixel.
