Realistic One-Shot Mesh-Based Head Avatars

We present a system for the creation of realistic one-shot mesh-based (ROME) human head avatars. From a single photograph, our system estimates the head mesh (with person-specific details in both the facial and non-facial head parts) as well as the neural texture encoding, local photometric and geometric details. The resulting avatars are rigged and can be rendered using a deep rendering network, which is trained alongside the mesh and texture estimators on a dataset of in-the-wild videos. In the experiments, we observe that our system performs competitively both in terms of head geometry recovery and the quality of renders, especially for cross-person reenactment.
