Comment on Not likely to be AI-generated or Deepfake
vithigar@lemmy.ca 1 month agoIt is absolutely not true of all AI images. I’d be surprised if it’s even true about most AI images.

Just saying that because you feel like it’s true or because you’ve participated in that line of thought for even 5 seconds?
AI images come from a noise map, it’s true cause they generate from it in a consistent manner.

I’m saying it because it’s not only obvious with even a moments thought (you can literally just ask it for an entirely red image or whatever), but also because it’s easily provable.

So I ask you the same question. Did you just say that because you felt like it was true?

The average brightness values of those are both middle of the road grey. Sorry I should have rephrased as I misspoke calling it beige but the point still stands that has the most average toned color.
If you look they are middling around 50-60% where as a similar red photo intake would likely have a higher contrast and an average color with a higher brightness.

I’d expect that many images are going to be somewhere near 50% grey if you average their luminance out overall. That’s just the average of every colour though. The fact that averaging a range of things tends toward a standard distribution isn’t particularly surprising. Again though, it’s not hard to get a diffusion model to generate something outside of that expectation.
