Dear Users, I have a problem in finding the PSNR & MSE for tow images that I do a skin detection on the first one and see the PSNR & MSE for them and that is the code that I did; I need the answer for me research clc clear all close all %Find MSE and then you can go for PSNR & SNR. %For the gray image (0 to 255), convert both the image to double. im1 = imread(('D:\ziyad PHD\New Research\1234.jpg')); I = imresize (im1,[256 256] ); I = rgb2gray(I); %figure(1),imshow(I); im2 = imread('D:\ziyad PHD\New Research\12345.jpg'); I2 = imresize (im2,[256 256] ); I2 = rgb2gray(I2); %figure(2),imshow(I2);
[M, N] = size (I); squaredErrorImage = (double(I) - double(I2)) .^ 2; mse = sum(sum(squaredErrorImage)) / (M*N);
PSNR = 10*log(256*256/mse) / log(10); % Alert user of the answer. message = sprintf('The mean square error is %.2f.\nThe PSNR = %.2f', mse, PSNR); msgbox(message);

What is a "tow" image?
Have you tried the functions psnr() and immse() in the Image Processing Toolbox?

Dear Image Analyst, I am so sorry for the miss spelling that happen due to the computer, I meant "two images" that is all of it thanks again
