PNG is lossless, so I don't get the quality comparison.

I don't think this approach can compete with JPEG and newer transform based variants for natural photos (event at edge cases), but seems like it would be nice for lossy compression of logos/general internet pics.

The point is, is that technique in between JPEG and PNG in terms of quality/size or is it worse than JPEG altogether ?
