High-Speed Face-Tracking for Dynamic Facial Projection Mapping
- bhouston 2y agoNeat stuff. I wonder if one could use a neural network to try to do prediction as well. Human movements are super stereotyped in the face and you could likely predict with decent accuracy the next frame given the previous frames.
- tsumnia 2y agoCheck out a lot of DisneyResearchHub's videos on YouTube. They are regularly posting research on object/face tracking and projections. That said as you mentioned faces are pretty stereotyped. We "solved" face mapping two decades ago with Tim Cootes and Paul Ekman's work. We're able to quickly map rough estimates using traditional haar cascade classifiers and Viola-Jones with AdaBoost. Neural Networks may help, but we have other solutions that also handle the problem with "relative" ease (ignoring lighting, occlusion, etc.)
- _flux 2y agoPretty cool. I've had this idea of converting face data into MIDI CC data to use with DAWs or synths, this could be a useful algorithm for it. Is the source code available?
- sporkl 2y agoNot this project, I've seen this something like this done with Google's MediaPipe models to get face tracking data into Max/MSP. https://cycling74.com/forums/n4m-facemesh-handpose-google-mediapipe https://cycling74.com/forums/n4m-facemesh-handpose-google-me...

- Hugsun 2y agoWhat sort of propaganda do you forsee this enabling?
- croes 2y ago„Leaked“ videos of political enemies saying abysmal things The Protocols of the Elders of Zion on steroids.
- grayhatter 2y agoUh... this is a white paper about projecting an image onto a moving face. Not super imposing, but projecting... with a projector... using light... so what exactly are you worried about with this tech? Or is it just that you're afraid of face tracking in general? And it's not really about this topic specifically?
- croes 2y agoIt’s about high speed face tracking. Can you imagine other use cases than projection?
- grayhatter 2y ago> Can you imagine other use cases than projection? yes vtubers human interface device for quadriplegics automated camera tracking/zoom for video calls emotion recognition support software for people with difficulty reading or understanding emotions (ASD) truly smart, smart home that can track and respond to gaze, e.g. "can you turn off that light" and it will turn off the light they're looking at sleep detection for smart locks liveness detection for identify verification systems vr tracking for interactions that both escape the uncanny valley, and feel more real time need more?
- croes 2y agoYes, list the malicious ones too.
- xfeeefeee 2y agoThe artistic possibilities of this are really fascinating. Looking forward to what people come up with! Projection mapping interactive art is always mesmerizing

- addandsubtract 2y agoWhat is the SotA OSS for face tracking these days? I've never been able to make face tracking work without having alignment issues during movement.
- brcmthrowaway 2y agoYou mean lag? try mediapipe w/ gpu support
- zipy124 2y agoI don't know if it's SoTa but previously in a joint academic+industrial project I've had very good success with faceboxes for face tracking and then adaptive Wing loss for facial alignment. With c++ and an ONNX runtime, I achieved very fast and accurate results, being robust to lighting and harsh angles. https://github.com/protossw512/AdaptiveWingLoss https://github.com/protossw512/AdaptiveWingLoss https://github.com/sfzhang15/FaceBoxes https://github.com/sfzhang15/FaceBoxes
- vessenes 2y agoOoooh, this is so cool. I didn’t realize I was seeing projected ‘makeup’ on faces until they showed some lower latency prior work. Once I saw it, I could see occasional misalignment. But, this is just an awesome and fun thing. I can imagine it being just amazing for live theater costuming and story telling. That said, it looks like the tech currently works at 1-2m range. I’d guess this is because that’s an easy range for a projector to work at and provide high res, in which case there’s no reason you couldn’t get a zoom setup going. Perhaps some enterprising director of the next Disney theater production will put the money in to get this working reliably on stage.
- suyash 2y agoWould love to know how to build such a system but with a normal camera and projector if possible for creative art+tech projects!
- brcmthrowaway 2y agoCan't mediapipe detect faces at 60fps?
- m3kw9 2y agoIs good but when you need that extra lens shift camera, it goes from mass market to super niche.
- echelon 2y agoIt seems like they've done two things here - the physical optical apparatus setup and the algorithm. I'm wondering why the physical alignment is so important. Are camera distortion models and mapping, view projection, etc. just too slow or low quality to run? I suppose I'll have to take a look at their paper later.
