Why is it not working? I've attached a demo for computing PSNR that does not use the built-in psnr(). It's used as an alternate to ssim -- it was used a lot before ssim came along.

Then get the code - it's in the lastest (and probably some older) version of MATLAB, or program it up yourself from the definition.
