NPGA: Neural Parametric Gaussian Avatars

no code implementations29 May 2024 Simon Giebenhain, Tobias Kirschstein, Martin Rünz, Lourdes Agapito, Matthias Nießner

In contrast to previous work, we condition our avatars' dynamics on the rich expression space of neural parametric head models (NPHM), instead of mesh-based 3DMMs.

HeadCraft: Modeling High-Detail Shape Variations for Animated 3DMMs

no code implementations21 Dec 2023 Artem Sevastopolsky, Philip-William Grassal, Simon Giebenhain, ShahRukh Athar, Luisa Verdoliva, Matthias Niessner

The decomposition of the parametric model and high-quality vertex displacements allows us to animate the model and modify it semantically.

GaussianAvatars: Photorealistic Head Avatars with Rigged 3D Gaussians

1 code implementation4 Dec 2023 Shenhan Qian, Tobias Kirschstein, Liam Schoneveld, Davide Davoli, Simon Giebenhain, Matthias Nießner

We introduce GaussianAvatars, a new method to create photorealistic head avatars that are fully controllable in terms of expression, pose, and viewpoint.

DiffusionAvatars: Deferred Diffusion for High-fidelity 3D Head Avatars

no code implementations30 Nov 2023 Tobias Kirschstein, Simon Giebenhain, Matthias Nießner

DiffusionAvatars synthesizes a high-fidelity 3D head avatar of a person, offering intuitive control over both pose and expression.

NeRSemble: Multi-view Radiance Field Reconstruction of Human Heads

no code implementations4 May 2023 Tobias Kirschstein, Shenhan Qian, Simon Giebenhain, Tim Walter, Matthias Nießner

We focus on reconstructing high-fidelity radiance fields of human heads, capturing their animations over time, and synthesizing re-renderings from novel viewpoints at arbitrary time steps.

AIR-Nets: An Attention-Based Framework for Locally Conditioned Implicit Representations

1 code implementation22 Oct 2021 Simon Giebenhain, Bastian Goldlücke

This paper introduces Attentive Implicit Representation Networks (AIR-Nets), a simple, but highly effective architecture for 3D reconstruction from point clouds.
