Removal of Salt and Pepper Noise Using 2D Median Filtering

Noise is a redundant signal that may occur in the image. Salt and Pepper noise is also recognized as impulse noise, independent noise or random noise, random occurrence of black and white pixels .The random occurrence of black and white pixels is Salt and Paper noise. Image de-noising is the first step in analysing, restore quality of the image. In this paper we use 2D median filter for salt and pepper noise without the use of medfilt2 FUNCTION. Median filter is a type of non-linear filter used to condense the amount of intensity variant between one pixel and the other pixel.
