The picture resolution of the examples is really poor... Difficult to see if it works well or not...

Original paper: https://arxiv.org/abs/2203.10496

Unfortunately the source code does not appear to be available.

This is a quite interesting area because it sits between the more traditional (pure 3d mesh based) models [1] (which are wonderful for 3d contours and precision, but typically don't handle textures, lighting etc) and modern GANs which "simply" deform images (i.e. deep fakes, style transfer).

The challenge is that the deformation is not straight-forward at all! That's why it truly helps (as this paper shows) to use some 3d knowledge in aiding the deformation.

But yes, I'd love to see the code for this. Shame it's not available.

[1] i.e. something like STAR from MPI: https://star.is.tue.mpg.de/

This is a very great AI that could be put to great use in the right hands, mostly at fitness centers and weight loss programs. A great motivator for those that could work for their ideal body type. Although it could easily be abused with people getting catfished online, I think the positives far outweigh the negatives. I remember when this type of body morphing could only be done with someone with advanced expeirence on Adobe Photoshop. Now its been reduced to sliders and its all automatic. Simply amazing.

My guess is that this will more popularly be used online or in metaverse like facial make up is used in real life, i.e., not as a motivator for exercising but just to put on a virtual body shape.

And see the irony -- The media and advertising industry is sometimes manipulating the real photos in similar ways [1], resulting partially an artificial social perception of what's a beautiful body.

or the porn industry...

With all the face filters out there I wondered why there weren’t any whole body filters yet that would allow people to form their bodies into whatever shape they want. Guess we won’t have to wait much longer.

Oh, I was hoping this would be something about AI helping me change my body from an overweight type to an in-shape type.

And I was hoping for a pair of bat wings and a pair of horns.

:shrug:

Maybe one day we'll only need to maintain a body that's just healthy enough to not confuse the algorithm and glitch out all the time.

Are there any clothing retailers currently utilizing this?

It’s fairly standard practice to do this sort of thing in Photoshop, but there are also enough models out there with various body types that you don’t need to go crazy.

That said I’m sure they’d love to automate the process, though in an age where plus sized models are everywhere it probably wouldn’t be used as much as it would have 10 years ago.

I don’t do (much) commercial work so I usually just get asked to slim down the mother of the bride/groom.
