Abstract: This paper presents the study and comparison of various salt & pepper noise reduction techniques for the gray scale images. In this paper we have discussed various linear and non-linear filters. Study of all algorithms and compare these to determine better detail preserving algorithm. This survey provides help to researchers for selecting the best algorithm with detail preserving for the removal of salt & pepper noise from the gray scale image.
Keywords: impulse noise, linear filter, non-linear filter
