Re: The answer of your question is right here

There is signal (the brightness of the red patch), I think your point more precisely is that there is no high frequency signal.

My point was a little more abstract than that. I’m not saying that there isn’t a physical level there...obviously, as you noted, if there’s a color there then there’s some information representing that. I was trying to bring attention to the fact that the poster’s process for evaluating noise has completely discarded signal. As you noted, the poster’s comparison is of noise vs. noise when it should be s/n ratio vs. s/n ratio.

Well I think we’re almost saying the same thing...so that’s good enough for me!
