I'm sure this could have applications in porn as well. Want to cater to someone's specific kink? Just generate it.

I do wonder if we'll ever reach a liberal enough society to be OK with machine-generated porn of all types, especially those taboo or illegal now (child pornography, sadism, zoophilia, etc). I could foresee it being banned before it even gets commercialized, which in my opinion would be unfortunate because I could see it as the methadone of porn to the "real stuff's" heroin.

That's already illegal in the US:[0]

> Child pornography under federal law is defined as any visual depiction of sexually explicit conduct involving a minor (someone under 18 years of age). Visual depictions include photographs, videos, digital or computer generated images indistinguishable from an actual minor, and images created, adapted, or modified, but appear to depict an identifiable, actual minor.

But that's not so in Japan. So one ought take care when torrenting Japanese films in the US.

Interesting moral implications. Should e.g. child porn still be illegal if no child is harmed? I think most people's natural reaction would be of course it should be illegal, it's child porn!

Forgive me for being off-topic, this comment resonated with me to the point that I went to your profile and read your other posts.

Much to my surprise, I remember reading some of them. I don't know who you are, but you're a good writer.

You make a good point and I think the upper-end of models will continue to be in demand (besides, these computationally generated images were trained at least in part from human photos).

However, if I were just an above-average model, where the main function is to display clothes rather than weave a narrative, I might be worried about this technology because many use-cases of models may be in jeopardy from this technology.

Is this really generating anything new or is it essentially just morphing between existing photos that it's been trained on? It would be interesting to take some of these GAN demos and write a utility where for each output, have it find the closest-matching training input, and see how similar it is.

This similarity of model output to training data, by pixel to pixel similarity, is often included in ML papers. The GAN here will very likely be producing uniques images in each case, some will be closer to the training data. But in general GANs are very capable and can for instance imagine a person with red hair wearing a green jacket even if it has never seen this combination of things before.

To answer this one would need to invest time into researching something that might potentially deflate the AI hype, so no one is doing it. Training dataset similarity analysis I usually see in these papers is downright laughable.

would this mean that outside of runway models, you wouldn't need models to showcase your clothing anymore since you can just "wrap" your clothes over these AI humans?

Somehow they'll have to find a way around lookalikes. A real human who believes the rendering is actually their image and likeness. So they'll have to have a way to prove that there was no "contamination". Funny enough, there was a case[1] of a real person thinking a model on a website was him but it turned out the image was that of an altogether different person that just looked like them, uncannily. For illustratio…

We simply use `bod2vec` to enforce a perimeter around trademarked personas. One simply chooses a suitable metric and embedding, and a safe distance, like (kDash-prezBurundi)², and any corporate avatar closer than that to a trademarked bod has to pay royalties at an inverse-square rate.

I've tried a couple of times to do this. The latest tech at the time had trouble with longer range structure, so things would start to look weird, with limbs just not looking right. I think it's totally doable, a way that I think wold work is use a nn to get the pose data from the graph and then generate the image from that pose data. Pretty sure it work, if you know what you are doing. Marketed right it will make big big money in the coming years. I just can't bring myself to invest the 100s of hours to get it running and into a marketable product. Can't stand programming anymore.

It’s fascinating how in the 80s and 90s we imagined virtual worlds being populated by 3D graphics built on modeled / digitized wireframes — and then this technology comes out of nowhere in the past decade. The holodeck seemed so implausible in its ability to just synthesize things. Doesn’t seem so implausible anymore. “Computer: Sherlock Holmes, in his study, speaking with Albert Einstein.”

Stop peddling meaningless hype. Current 3D rendering technology is lightyears ahead[1] of these AI toys and you can trivially parametrize it. Many games already do. So if you want to generate people, you already can do that while having full control, instead of some glitchy sliders.

Something genuinely useful might, perhaps, be achieved by applying GANs to parameters of those 3D models to allow easier customization, but I haven't seen any work in that direction.

Another vote for agree and disagree. Take for example Japan - the land of anime girls on every piece of advertising. How much would the demand for human models expand if illustrated characters were not an alternative? There's a scarcity in the type of human beauty that's sought after by the fashion industry. What if that scarcity didn't exist? If people grow up with this new economic model of beauty and scarcity, may…

I’m posting this message from a local train in rural japan. The sides are plastered with ads but nowhere where i look at can i see anime girls.

While i know few instances where they exist, that’s just not the reality in japan. Akihabara is as much of a japan as Silicon Valley is Usa. At certain level yes but on the other hand not at all.
