SPHEAR: Spherical Head Registration for Complete Statistical 3D Modeling

SPHEAR: Spherical Head Registration for Complete Statistical 3D Modeling

We present SPHEAR, an accurate, differentiable parametric statistical 3D human head model, enabled by a novel 3D registration method based on spherical embeddings. We shift the paradigm away from the classical Non-Rigid Registration methods, which operate under various surface priors, increasing reconstruction fidelity and minimizing required human intervention. Additionally, SPHEAR …
