use this code
clear all
close all
clc
image=imread('cameraman.tif');
figure(1)
imshow(image);
drawnow
image_n=imnoise(image,'salt & pepper',0.1);
figure(2)
imshow(image_n)
drawnow
I=double(image);
K=double(image_n);
[m n]=size(I);
MSE=(I-K).^2;
MSE=sum(MSE(:))/(m*n)
PSNR=10*log10(255.^2/MSE)
correlation = corr2(I,K)
