I need matlab codes.Please give all required information as comment 1) Load and display cameraman.tif image which is present in Matlab a) Add salt and pepper noise to the original image by using imnoise function with noise density of 0.02 b) Apply 3x3 averaging filter to the noisy image by using fspecial function c) Apply median filter to the noisy image using medfilt2 with a 3x3 window, a 5x5 window and 11x11 window. Compare the resulting images for averaging and median filters.. For each window size, comment on hovw effectively the noise is reduced while sharp edges and features in the image are preserved.
