Yes. OBS offers it. Teams and Zoom have guesswork-based imitations.
And where can I find the OBS implementation of this work?

I found the chroma key implementation, but this seems to assume you have a green screen or similar: https://github.com/obsproject/obs-studio/blob/master/plugins...
I thought GP was asking for an implementation of background removal without a green screen.

#13What's novel about this?
If you have a background picture, you have all the info you need to identify your subject - just plain subtraction. I think this is what the Photo Booth app on my circa-2012 MacBook does, quite effectively.

That's definitely my impression, and to my knowledge, OBS doesn't offer it. I'd be thrilled to learn otherwise.

The project page has a video comparison against previous state of the art. You can't just subtract the background if it's not 100% static and stable. Further, the novelty seems to be less artifacts, especially around hair and eyeglasses.

#16I recently tried working on this with OpenCV but it didn't quite work like I expected. I had problems with artifacts caused by my own shadows

#17Peripheral: What is the benefit of halving these artificial backgrounds? Apart from „it’s fun“, which wears off after about a minute? In my experience (Zoom Meetings), there’s blurring/artefacts around the edge of the head and the image quality seems to suffer as well.
I had a meeting where one participant uses an actual green screen, and the difference was remarkable, with none of the issues above.

This is a question we’ve gotten quite a bit (second author here).
A good intuition is that if it were easy to do it already with any background, professional studios wouldn’t be spending so much money on green screens. Background subtraction is pretty poor in general without very constrained setups. Our goal is really to provide professional quality without any of the equipment.

#19Is it fast enough to operate on a live video feed from, say, a webcam?
I recently tried to do this with Python OpenCV but it was too slow and had a lot of artifacts caused by my own shadows.

#20Is it fast enough to operate on a live video feed from, say, a webcam?
I recently tried to do this with OpenCV but I didn't figure out how to make it fast enough and remove artifacts caused by my own shadows.
