PSAvatar: A Point-based Morphable Shape Model for Real-Time Head Avatar Animation with 3D Gaussian Splatting. (arXiv:2401.12900v4 [cs.GR] UPDATED)
cs.CV updates on arXiv.org arxiv.org
Despite much progress, achieving real-time high-fidelity head avatar
animation is still difficult and existing methods have to trade-off between
speed and quality. 3DMM based methods often fail to model non-facial structures
such as eyeglasses and hairstyles, while neural implicit models suffer from
deformation inflexibility and rendering inefficiency. Although 3D Gaussian has
been demonstrated to possess promising capability for geometry representation
and radiance field reconstruction, applying 3D Gaussian in head avatar creation
remains a major challenge since it is difficult for …
