Hi! I'm Guy. I received my Bachelor's degree in Mathematics from Tel-Aviv University. During my Master's studies at TUM, I joined the Visual Computing group, where I have worked on face-swapping, GANs, and neural rendering of point clouds. I later joined the group as a PhD candidate with Prof. Matthias Nießner.

Dynamic Neural Radiance Fields for Monocular 4D Facial Avatar Reconstruction
Guy Gafni, Justus Thies, Michael Zollhöfer, Matthias Nießner
CVPR 2021 (Oral)
Given a monocular portrait video sequence of a person, we reconstruct a dynamic neural radiance field representing a 4D facial avatar. The radiance field is conditioned on blendshape expressions, which allow us to then photorealistically synthesize novel head poses as well as novel facial expressions of the person. This can be used for self-reenactment, novel view synthesis and cross-subject reenactment.
