    • Accurate Real-time 3D Gaze Tracking Using a Lightweight Eyeball Calibration 

      Wen, Quan; Bradley, Derek; Beeler, Thabo; Park, Seonwook; Hilliges, Otmar; Yong, Jun-Hai; Xu, Feng (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      3D gaze tracking from a single RGB camera is very challenging due to the lack of information in determining the accurate gaze target from a monocular RGB sequence. The eyes tend to occupy only a small portion of the video, ...

    • Facial Animation with Disentangled Identity and Motion using Transformers 

      Chandran, Prashanth; Zoss, Gaspard; Gross, Markus; Gotardo, Paulo; Bradley, Derek (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      We propose a 3D+time framework for modeling dynamic sequences of 3D facial shapes, representing realistic non-rigid motion during a performance. Our work extends neural 3D morphable models by learning a motion manifold ...

    • Facial Expression Synthesis using a Global-Local Multilinear Framework 

      Wang, Mengjiao; Bradley, Derek; Zafeiriou, Stefanos; Beeler, Thabo (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We present a practical method to synthesize plausible 3D facial expressions for a particular target subject. The ability to synthesize an entire facial rig from a single neutral expression has a large range of applications ...

    • Fast Dynamic Facial Wrinkles 

      Weiss, Sebastian; Chandran, Prashanth; Zoss, Gaspard; Bradley, Derek (The Eurographics Association, 2024)
      We present a new method to animate the dynamic motion of skin micro wrinkles under facial expression deformation. Since wrinkles are formed as a reservoir of skin for stretching, our model only deforms wrinkles that are ...

    • Fast Nonlinear Least Squares Optimization of Large-Scale Semi-Sparse Problems 

      Fratarcangeli, Marco; Bradley, Derek; Gruber, Aurel; Zoss, Gaspard; Beeler, Thabo (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Many problems in computer graphics and vision can be formulated as a nonlinear least squares optimization problem, for which numerous off-the-shelf solvers are readily available. Depending on the structure of the problem, ...

    • Graph-Based Synthesis for Skin Micro Wrinkles 

      Weiss, Sebastian; Moulin, Jonathan; Chandran, Prashanth; Zoss, Gaspard; Gotardo, Paulo; Bradley, Derek (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      We present a novel graph-based simulation approach for generating micro wrinkle geometry on human skin, which can easily scale up to the micro-meter range and millions of wrinkles. The simulation first samples pores on the ...

    • Improved Lighting Models for Facial Appearance Capture 

      Xu, Yingyan; Riviere, Jérémy; Zoss, Gaspard; Chandran, Prashanth; Bradley, Derek; Gotardo, Paulo (The Eurographics Association, 2022)
      Facial appearance capture techniques estimate geometry and reflectance properties of facial skin by performing a computationally intensive inverse rendering optimization in which one or more images are re-rendered a large ...

    • Interactive Sculpting of Digital Faces Using an Anatomical Modeling Paradigm 

      Gruber, Aurel; Fratarcangeli, Marco; Zoss, Gaspard; Cattaneo, Roman; Beeler, Thabo; Gross, Markus; Bradley, Derek (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Digitally sculpting 3D human faces is a very challenging task. It typically requires either 1) highly-skilled artists using complex software packages for high quality results, or 2) highly-constrained simple interfaces for ...

    • Learning Dynamic 3D Geometry and Texture for Video Face Swapping 

      Otto, Christopher; Naruniec, Jacek; Helminger, Leonhard; Etterlin, Thomas; Mignone, Graziana; Chandran, Prashanth; Zoss, Gaspard; Schroers, Christopher; Gross, Markus; Gotardo, Paulo; Bradley, Derek; Weber, Romann (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Face swapping is the process of applying a source actor's appearance to a target actor's performance in a video. This is a challenging visual effect that has seen increasing demand in film and television production. Recent ...

    • A Perceptual Shape Loss for Monocular 3D Face Reconstruction 

      Otto, Christopher; Chandran, Prashanth; Zoss, Gaspard; Gross, Markus; Gotardo, Paulo; Bradley, Derek (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      Monocular 3D face reconstruction is a wide-spread topic, and existing approaches tackle the problem either through fast neural network inference or offline iterative reconstruction of face geometry. In either case ...

    • Practical Person-Specific Eye Rigging 

      Bérard, Pascal; Bradley, Derek; Gross, Markus; Beeler, Thabo (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We present a novel parametric eye rig for eye animation, including a new multi-view imaging system that can reconstruct eye poses at submillimeter accuracy to which we fit our new rig. This allows us to accurately estimate ...

    • Shape Transformers: Topology-Independent 3D Shape Models Using Transformers 

      Chandran, Prashanth; Zoss, Gaspard; Gross, Markus; Gotardo, Paulo; Bradley, Derek (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Parametric 3D shape models are heavily utilized in computer graphics and vision applications to provide priors on the observed variability of an object's geometry (e.g., for faces). Original models were linear and operated ...

    • Stylize My Wrinkles: Bridging the Gap from Simulation to Reality 

      Weiss, Sebastian; Stanhope, Jackson; Chandran, Prashanth; Zoss, Gaspard; Bradley, Derek (The Eurographics Association and John Wiley & Sons Ltd., 2024)
