The beginning of the end of photography (video & still) as evidence.

The real title to this thread should read:

"Nvidia released details of a new face creating algorithm."

But I had to keep up forum appearances and be click-baity.

Several prominent companies and universities are working on similar human being creation technology.

Also, before anyone brings up the "these are stills, not video". Yes, video is much harder to create convincingly. (Though keep in mind they don't have to create the entire 3 model for each person. They just need to create a tweakable 3d model and then skin it & tweak it for each person.) (And companies also keep that tech much more closer to their chest... until it is outdated, of course.)


All of the below human beings do not exist.

The faces above don’t seem particularly remarkable. They could easily be taken from, say, Facebook or LinkedIn. In reality, they were dreamt up by a new kind of AI algorithm. Nvidia researchers posted details of the method to produce completely imaginary fake faces with stunning, almost eerie, realism <snip>. The researchers, Tero Karras, Samuli Laine, and Timo Aila, came up with a new way of constructing a generative adversarial network, or GAN.

GANs employ two dueling neural networks to train a computer to learn the nature of a dataset well enough to generate convincing fakes. When applied to images, this provides a way to generate often highly realistic fakery.
In the most recent work, the researchers took inspiration from a technique known as style transfer to built their GAN in a fundamentally different way. This allowed their algorithm to identify different elements of a face, which the researchers could then control. A video produced by the researchers shows how the approach can also be used to play with, and remix, different elements, like age, race, and gender--or even freckles.

How does this relate to there being a time soon where video & still photography should no longer be used as evidence? I admit they are not exactly the same field, but they are sister fields, and they are more than tangentially related.

We are not that far away from someone being able to make a video of you doing whatever the **** they want. Cheaply.

Just like in photoshop, that will happen when you are able to show a group of people 2 examples and they cannot tell beyond a 50/50 chance which one is real.

Also, it is very likely that by 2025, or at the most 2030, there will be an extremely popular celebrity (most likely a youtube celebrity) outed. Outed as not an actual human being. (Though, somewhat non-intuitively, creating completely fake and unique audio (speech) can be harder than creating completely fake video.) They will be tailored to make $$$. And we all know if it makes money, it will happen eventually.
