Abstract

This paper studies the concept of noise, how noise is added to an image and various noise removal techniques. This paper contributes a comparative analysis of noise removal techniques such as ‘salt & pepper noise’, and ‘gaussian noise’’ with reference to original image. For experimental purposes, initially we observed the original image with respect to following parameters: mean, variance, entropy etc. Then we observed the image after adding different types of noise and lastly we have observed which noise removal technique is suitable for which noise for denoising. We have performed this work on MATLAB.

Keywords: Gaussian noise, Salt & Pepper noise, mean, median, Binary image
