I was just commenting on the way that the author of that webpage seems to have compared the various algorithms. I don't have a problem with using a reconstructed image, I'd like to see them use a lot of different types of images with reconstructed being maybe one of them. Each algorithm tends to be better with different types of images, and reconstructed ones might even exaggerate those differences. Different algorithms will appear at the top, with different images.

Regardless, when dealing with priceless images of other worlds, it should be a felony to compress them in a lossy mode for any purpose other than to use as thumbnails (but the underlying image should be made available), or printed pictures in a magazine.

Unfortunately, it's lossly compressed pictures on various websites which get so jacked up that people can't tell the difference between cornfields in Iowa and compression artifacts.

digital images too. Maybe we could make even simple possession of magnifijuana a misdemeanor.
