Face2Face: Real-time Face Capture and Reenactment of RGB Videos [video]

This demo is doubly amazing: First, the obviously impressive (and slightly unsettling in its implications) manipulation of the target face, but second, the fact that this is all being done with a single RGB camera.

Consider the massive rig required to perform the at-the-time groundbreaking performance capture for the game L.A. Noire: http://i.kinja-img.com/gawker-media/image/upload/s--y6fmsAIU... This is how far computer vision has come in five years.

In terms of gaming applications this could be huge for virtual reality avatars. You can still be anonymous but still convey facial expressions with a webcam!

I'm curious how you think a webcam will be able to read your facial expression when you have a VR headset on you face.

smaller vr rigs should just cover the eyes. or maybe there is a small camera hanging under the vr rig to capture face elements.

This research uses a camera to capture the mouth area and strain sensors for the upper face (that part can obviously be improved).

This is insanely awesome. Something that comes to my mind is the use of this for dubbing movies and TV series; I'm very sensitive about correctly syncing what's being said to what we see, to the point where I only watch movies in their native tongue - even if I don't know the language and need subtitles. This could be a game-changer.

It's even cooler since you could even do this retroactively if you had the original footage of the dubbing voice actor.

I'm curious, how do you both read subtitles and watch that the sound is properly synced to an actor's lips? I can't read that fast, so I spend 80% of my time "watching a movie" simply reading text on the bottom of the screen.

    > I can't read that fast

I can't speak for the op, but I can read a great deal faster than most people speak.

Subtitles aren't synched to actor's lips. He talked about dubbed voices, not subtitles. :)

One of the references towards the end of the video mentions using this for translation, so that's definitely one of the intended applications.

Very well done. The best part is how they re-enact the mouth/teeth to look so real by capturing it by sampling earlier parts in the video to then use that on the non expression still or loop. I was blown away when Trump's teeth looked so real then they explained this process and why.

This could be huge (yuuuge) in games and virtual spaces. At GDC Unreal 4 has a demo recently and seems we are approaching that era[1]

One of the barriers existing in webcam meetings is the inability to make eye contact. It seems subtle but I think it is more important than one might intuitively think.

I've thought a lot about how to overcome this and came up with nothing but cameras beneath the screen (which Apple seems to have worked on but we have yet to see it: http://appleinsider.com/articles/09/01/08/apple_files_patent...). This technology could possibly provide a competing solution.

Discerning fake video from real just got a lot harder. Video is one of the last bastions of honest evidence.

I heard light source has been a way to determine whether something is likely to be fake or not.

The data vacuuming companies (FB, Google, ad networks, etc.) collect the information about us required to know how to manipulate us and technologies such as this one represent the tools to actually get it done.

Conan could use this for his fake celebrity interviews instead of just cutting the mouth out of an image. :)

Imagine live edit of your video conversations, that attaches joyful emotions to any mention of an advertised brand.

The paper is great, but I wanna see some source code!

I don't think they want the world to see some source code, should it get into the wrong hands, though the repercussions of this work are bound to hit us sometime. [1]

Where can I find the paper?

The video made me feel very uncomfortable, and it takes a lot to make me feel that way.

Faking news got an order of magnitude easier :)

It would be cool to use this to fix movie footage in post production. You could just copy a face over if the actor screwed up

Or bringing back dead actors using past footage!

What is Target Actor and what is Reenactment Result? The former looks better to me.

Taget actor is the source material that they're changing, and the latter is the result of that.

Does anyone have the link to the paper?

Terrifying, amazing but terrifying.

This is impressive.

The title is really underwhelming compared to how cool the demo is.

Hilarious and scary at the same time. The admissibility of videos in courts is becoming more and more questionable.

Wow.
