VRMM: A Volumetric Relightable Morphable Head Model
CoRR(2024)
摘要
In this paper, we introduce the Volumetric Relightable Morphable Model
(VRMM), a novel volumetric and parametric facial prior for 3D face modeling.
While recent volumetric prior models offer improvements over traditional
methods like 3D Morphable Models (3DMMs), they face challenges in model
learning and personalized reconstructions. Our VRMM overcomes these by
employing a novel training framework that efficiently disentangles and encodes
latent spaces of identity, expression, and lighting into low-dimensional
representations. This framework, designed with self-supervised learning,
significantly reduces the constraints for training data, making it more
feasible in practice. The learned VRMM offers relighting capabilities and
encompasses a comprehensive range of expressions. We demonstrate the
versatility and effectiveness of VRMM through various applications like avatar
generation, facial reconstruction, and animation. Additionally, we address the
common issue of overfitting in generative volumetric models with a novel
prior-preserving personalization framework based on VRMM. Such an approach
enables accurate 3D face reconstruction from even a single portrait input. Our
experiments showcase the potential of VRMM to significantly enhance the field
of 3D face modeling.
