This makes me think about descartes' devil, if in such a short time we are able to generate fake bodies. What if we could generate fake people (not necessarily conscious but behaving as if they are.) in the future.

and with enough advances in brain/computer interfaces one could live a whole life without meeting a real human . In fact, in that case, one wouldn't even need accurate models since there would be no baseline to compare to.

Or maybe, we could implement surgical lenses that applies a filter on other people generating a fake person.

You can basically, eliminate _ism(s) in the workplace by making everyone look and sound the same.

People can pay to make their images in others' eyes different. Or one can pay to make their spouse look like a their true love in their eyes.

Exactly. If you're Gap and have a lineup with thousands of articles of clothing, why would you go through the trouble of procuring models? You have to deal with modeling agencies, photographers, set managers, etc... When the AI gets good enough, it will be even better than the alternative. It will serve ads showing only your body type. Maybe the models will even have....your face.

That would be great. You don't need a floor length mirror and changing rooms if you can just have your rendered body and face to exchange clothes on. Need to get accurate measurements for the right dimensions though.

That would depend on very accurate cloth physics simulation as well. This is way beyond what the article is showcasing, it's not even in the same ballpark.

They can use this technology to generate a model to fit a particular user profile. Filter bubbles are going to get even better! Or maybe they can ask user to upload his photo and feed that as a prior to the model so it can generate visuals of that person wearing different dresses. That would be cool!

That would be neat. Imagine going to a site, adding some photos of yourself and seeing all the clothes as they would look on you based on your actual dimensions. You'd never have to wonder if something would look good on you. I imagine this would save a ton of shipping costs on returns.

The AI showed here is not even a step in that direction. If you want photo-realistic images of how a piece of clothing would look on your body you need:

- very accurate measurements of your body

- a very accurate representation of the materials used in that piece of clothing, including weight, tensile strength etc.

- a very accurate physics simulation matching the materials to your body measurements

The technology showcased here does nothing similar. It could perhaps generate pictures of what someone who looks sort of similar to your general body shape, as seen in your pictures, looks in clothes. It would be no better than what you currently have: look at the picture, and try to guess how well that fits your actual body.

Even worse, you would completely miss details like "the material is very stretchy, it looks good on the model's abs but it might look bad on my belly fat" because the AI would NOT be doing a simulation of how that clothing actually fits a human body - it's always producing an idealized simulation.

Edit: and to make this clear, I'm not saying that "the AI can't do that yet". I'm saying that the technique they are using can't achieve the goal you are talking about. There is nowhere near enough detail in pictures of clothing to get the kind of simulation you are looking for.

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,…

Looks better to me than a lot of what is on your video. The video is very nice and it's really good, however it's often not really photorealistic when it's supposed to be and I also don't believe it'll be possible to do raytracing at such performance it'll be usable for most people (mobile phones), for VR. This approach is a new way that sidesteps the issues of raytracing.

With all the work on making these ML models controllable it seems like they now have a decent concept of things like "tall person" or "wears glasses". I assume it would be entirely possible to replace the last few layers and generate 3d models instead of images. Nobody is doing that right now because nobody has training data for that, and generating such training data is hard (or expensive). But it seems like it should be in reach of someone with a profitable use case.

Amazing! This pretty much enables clothing brands to generate extremely targeted ads on the fly. Models can have similar body shape, hair style, skin colour to the user. Based on past photos the advertiser can figure out preferred colours, patterns and possibly even styles.

"Mirrors" in a store display that shows the clothes on "you". And conveniently adjusts your figure...

Couple this with the work in neural 3d rendering and we will probably have a new generation of 3d technology in a few years.

While AI models might replace catalogue models for small labels that are starting out (maybe) and for e-commerce companies (definitely). I highly doubt it that they will replace real models for large companies and fashion boutiques now or ever. Because what people (women and men) are buying is aspiration wrapped in dead plant fibers. The reason why I buy a dress from Hervé Leger is because I want to look like old sch…

In the future we are going to have neural fashion. People will use the knobs of an autoencoder to generate the clothes they like, preview them on artificial models , and then order them for manufacturing.

I expect that data to grow quickly over the next decade, assuming things like the 3D selfie camera on iPhones end up on the main camera too. (I expect they will end up on all the cameras, just for the value they’d add to AR).
