 This is a demo app showing face tracking and 3D Morphable Model fitting on live webcams and videos. It builds upon the 3D face model library [eos](https://github.com/patrikhuber/eos) and the landmark detection and optimisation library [superviseddescent](https://github.com/patrikhuber/superviseddescent).
