The Technology Behind Animoji by Apple Last year Apple releases their new phone Apple X that has an exciting feature called Animoji. I am so fascinated by this technology that I really want to make my own version of it. But the problem is I am really new in image processing stuff and I've no idea about the technology behind Animoji. So what is the technology behind the Applle Animoji and what sort of knowledge should I have if I want to build my own version of Animoji from scratch?
It's more like a soft answer (I am happy to update it later), but Alex Acero explained the technology behind aniomoji on this years ICASSP 2018. Here is the link. Basically, they are using so-called Blendshapes to estimate the positions of the muscles and then they are mapping them to the actual animoji model.
