clc clear all close all %Read an Image I = imread('C:\Users\shankar\Documents\MATLAB\filtering\box.jpg'); I=rgb2gray(I); figure(1),imshow(I); %Add multiplicative noise to the image J = imnoise(I,'speckle',0.01); figure(2),imshow(J); %Apply Lee filter K = Lee_filter_C(I,J,[5 5]); figure(3),imshow(uint8(K));
