Sadly his only quality measure is PSNR, which is a rather artificial measure
and does not necessarily tell you which is the best quality in your eyes.
However, although I read about "better" measures, I cannot currently remember
where.. But in general, one should use more than one measure (another equally
simple and not better one would be MSE, the mean square error).
