You could chop the image in half, call fliplr() to flip one of the halves, then check similarity with SSIM (See wikipedia) or something similar like PSNR.

There is an ssim() function in the Image Processing Toolbox. Or you cuold look for published articles on it here:

If you still want ssim(), upgrade to the latest version of MATLAB, or program it yourself with information from
