Can you say if you're using a lifting transform, why the reconstructed image approximation is not 512x512?

What if you just used imresize() on one of them? And then did the usual PSRN formula. Would that work for your purposes?

Make your reference image bigger to match the size of your super resolution image.

Sivakrishna Did you find how to calculate PSNR between an original image and the super resolution constructed one?
