I M Avatar: Implicit Morphable Head Avatars from Videos

1 code implementation CVPR 2022 Yufeng Zheng, Victoria Fernández Abrevaya, Marcel C. Bühler, Xu Chen, Michael J. Black, Otmar Hilliges

Traditional 3D morphable face models (3DMMs) provide fine-grained control over expression but cannot easily capture geometric and appearance details.

SNARF: Differentiable Forward Skinning for Animating Non-Rigid Neural Implicit Shapes

1 code implementation ICCV 2021 Xu Chen, Yufeng Zheng, Michael J. Black, Otmar Hilliges, Andreas Geiger

However, this is problematic since the backward warp field is pose dependent and thus requires large amounts of data to learn.

Continuous Conditional Generative Adversarial Networks (cGAN) with Generator Regularization

no code implementations27 Mar 2021 Yufeng Zheng, Yunkai Zhang, Zeyu Zheng

To partially alleviate this difficulty, we propose a simple generator regularization term on the GAN generator loss in the form of Lipschitz penalty.

Doubly Stochastic Generative Arrivals Modeling

no code implementations27 Dec 2020 Yufeng Zheng, Zeyu Zheng

Numerical experiments suggest that, in terms of performance, the successful model estimation for DS-WGAN only requires a moderate size of representative data, which can be appealing in many contexts of operational management.


Self-Learning Transformations for Improving Gaze and Head Redirection

2 code implementations NeurIPS 2020 Yufeng Zheng, Seonwook Park, Xucong Zhang, Shalini De Mello, Otmar Hilliges

Furthermore, we show that in the presence of limited amounts of real-world training data, our method allows for improvements in the downstream task of semi-supervised cross-dataset gaze estimation.
