Learning a Generalized Physical Face Model From Data

no code implementations29 Feb 2024 Lingchen Yang, Gaspard Zoss, Prashanth Chandran, Markus Gross, Barbara Solenthaler, Eftychios Sifakis, Derek Bradley

Physically-based simulation is a powerful approach for 3D facial animation as the resulting deformations are governed by physical constraints, allowing to easily resolve self-collisions, respond to external forces and perform realistic anatomy edits.

An Implicit Physical Face Model Driven by Expression and Style

no code implementations27 Jan 2024 Lingchen Yang, Gaspard Zoss, Prashanth Chandran, Paulo Gotardo, Markus Gross, Barbara Solenthaler, Eftychios Sifakis, Derek Bradley

At the core, we present a framework for learning implicit physics-based actuations for multiple subjects simultaneously, trained on a few arbitrary performance capture sequences from a small set of identities.

Artist-Friendly Relightable and Animatable Neural Heads

no code implementations6 Dec 2023 Yingyan Xu, Prashanth Chandran, Sebastian Weiss, Markus Gross, Gaspard Zoss, Derek Bradley

An increasingly common approach for creating photo-realistic digital avatars is through the use of volumetric neural fields.

A Perceptual Shape Loss for Monocular 3D Face Reconstruction

no code implementations30 Oct 2023 Christopher Otto, Prashanth Chandran, Gaspard Zoss, Markus Gross, Paulo Gotardo, Derek Bradley

In this work we propose a new loss function for monocular face capture, inspired by how humans would perceive the quality of a 3D face reconstruction given a particular image.

CADS: Unleashing the Diversity of Diffusion Models through Condition-Annealed Sampling

no code implementations26 Oct 2023 Seyedmorteza Sadat, Jakob Buhmann, Derek Bradley, Otmar Hilliges, Romann M. Weber

While conditional diffusion models are known to have good coverage of the data distribution, they still face limitations in output diversity, particularly when sampled with a high classifier-free guidance scale for optimal image quality or when trained on small datasets.

Continuous Landmark Detection With 3D Queries

no code implementations CVPR 2023 Prashanth Chandran, Gaspard Zoss, Paulo Gotardo, Derek Bradley

Neural networks for facial landmark detection are notoriously limited to a fixed set of landmarks in a dedicated layout, which must be specified at training time.

ReNeRF: Relightable Neural Radiance Fields with Nearfield Lighting

no code implementations ICCV 2023 Yingyan Xu, Gaspard Zoss, Prashanth Chandran, Markus Gross, Derek Bradley, Paulo Gotardo

Recent work on radiance fields and volumetric inverse rendering (e. g., NeRFs) has provided excellent results in building data-driven models of real scenes for novel view synthesis with high photorealism.

Adaptive Convolutions for Structure-Aware Style Transfer

2 code implementations CVPR 2021 Prashanth Chandran, Gaspard Zoss, Paulo Gotardo, Markus Gross, Derek Bradley

Style transfer between images is an artistic application of CNNs, where the 'style' of one image is transferred onto another image while preserving the latter's content.

ETH-XGaze: A Large Scale Dataset for Gaze Estimation under Extreme Head Pose and Gaze Variation

1 code implementation ECCV 2020 Xucong Zhang, Seonwook Park, Thabo Beeler, Derek Bradley, Siyu Tang, Otmar Hilliges

We show that our dataset can significantly improve the robustness of gaze estimation methods across different head poses and gaze angles.
