To evaluate this experimental compression codec, I didn’t use any of the standard test images or images found online in order to ensure that I’m not testing it on any data that might have been used in the training set of the Stable Diffusion model (because such images might get an unfair compression advantage, since part of their data might already be encoded in the trained model). I think it would be very interesting to determine if these images do come back with notably better compression.
