xooyoozoo,
Thank You for interesting comparsion and useful papers.
There was also the comparison between different jpeg2000 (kdu also) encoders vs jpeg, though pretty old. Not sure whether kdu is enough representative jpeg2000 encoder, anyway it was PSNR.

Can I ask You to post lossy images in png also?
