And for this solution to work the down sampling must happen inside the program, not in the file system, therefore all network-braking noise would have been already discarded. I see, maybe I just didn't get your point the first time. Anyway, what I was trying to say is that if you do view the downsampling as part of the network/program, you could apply the optimization procedure mentioned in the paper to a network that blurs its input. I assume that this would then generate network-breaking patterns that are imperceptible to the human eye, in the same way as happens in the paper.
