By and large various channels are utilized for disposing of various commotions like Mean channel evacuates the motivation noise, Median filter removes "salt and pepper" noise and Weiner channel evacuates noise that has tainted a sign. It depends on a factual methodology. we have advised that Median filter delivers best results against impulsive noise.
