What does adding surface blur really fix? Why could you not add similarly subtle network-breaking noise to a blurred image? If you think of blurring as downsampling, it is obvious that you also need downsampled noise to trick the NN.
- ivanca 12y agoThe noise is not random, one can see exactly where the artifacts were added (the white parts of the image). 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.
