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.
