I feel very much a sense of uncanny valley looking at the PDE-based images. The extreme jpeg images /look/ mechanically compressed, whereas the PDE images seem to be almost but not quite natural in the results. I'm curious as to what the results would be with an image compressed to say 1:10th its original size
