Hi Tina

PSNR can be calculated for the two image, one is input image and another ones in noisy affected image..

You can try with the example...

A = image1; B = image2;

C = psnr(A,B)

A is input image, B is noisy image, from this we can have a signal to noise ration result

See this link: http://www.cb.uu.se/~cris/blog/index.php/archives/490#more-490

I've also attached a file to do psnr for those people with antique versions of MATLAB before the psnr became a built-in function.
