Spatio-temporal motion completion using a sequence of latent primitives

no code implementations27 Jun 2022 Mathieu Marsot, Stefanie Wuhrer, Jean-Sebastien Franco, Anne Hélène Olivier

We address both problems by learning a motion prior that encodes a 4D human motion sequence into a sequence of latent primitives instead of one latent code.

Neural Human Deformation Transfer

Data-Driven 3D Reconstruction of Dressed Humans From Sparse Views

1 code implementation16 Apr 2021 Pierre Zins, Yuanlu Xu, Edmond Boyer, Stefanie Wuhrer, Tony Tung

We propose a data-driven end-to-end approach that reconstructs an implicit 3D representation of dressed humans from sparse camera views.

A Decoupled 3D Facial Shape Model by Adversarial Training

no code implementations ICCV 2019 Victoria Fernandez Abrevaya, Adnane Boukhayma, Stefanie Wuhrer, Edmond Boyer

Data-driven generative 3D face models are used to compactly encode facial shape data into meaningful parametric representations.

Analyzing Clothing Layer Deformation Statistics of 3D Human Motions

no code implementations ECCV 2018 Jinlong Yang, Jean-Sebastien Franco, Franck Hetroy-Wheeler, Stefanie Wuhrer

Recent capture technologies and methods allow not only to retrieve 3D model sequence of moving people in clothing, but also to separate and extract the underlying body geometry, motion component and the clothing as a geometric layer.

A Multilinear Tongue Model Derived from Speech Related MRI Data of the Human Vocal Tract

2 code implementations15 Dec 2016 Alexander Hewer, Stefanie Wuhrer, Ingmar Steiner, Korin Richmond

We present a multilinear statistical model of the human tongue that captures anatomical and tongue pose related shape variations separately.

A Robust Multilinear Model Learning Framework for 3D Faces

1 code implementation CVPR 2016 Timo Bolkart, Stefanie Wuhrer

Multilinear models are widely used to represent the statistical variations of 3D human faces as they decouple shape changes due to identity and expression.

Multilinear Wavelets: A Statistical Shape Space for Human Faces

1 code implementation13 Jan 2014 Alan Brunton, Timo Bolkart, Stefanie Wuhrer

We show that in comparison to a global multilinear model, our model better preserves fine detail and is computationally faster, while in comparison to a localized PCA model, our model better handles variation in expression, is faster, and allows us to fix identity parameters for a given subject.

Analysis of Farthest Point Sampling for Approximating Geodesics in a Graph

no code implementations19 Nov 2013 Pegah Kamousi, Sylvain Lazard, Anil Maheshwari, Stefanie Wuhrer

We show that $\mathcal{F}_{FPS}$ can be bounded in terms of the minimal value $\mathcal{F}^*$ of the stretch factor obtained using an optimal placement of $k$ sources as $\mathcal{F}_{FPS}\leq 2 r_e^2 \mathcal{F}^*+ 2 r_e^2 + 8 r_e + 1$, where $r_e$ is the ratio of the lengths of the longest and the shortest edges of the graph.
