Fast Nonlinear Least Squares Optimization of Large-Scale Semi-Sparse Problems
(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, ...
SoftSMPL: Data-driven Modeling of Nonlinear Soft-tissue Dynamics for Parametric Humans
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
We present SoftSMPL, a learning-based method to model realistic soft-tissue dynamics as a function of body shape and motion. Datasets to learn such task are scarce and expensive to generate, which makes training models ...
Style-Controllable Speech-Driven Gesture Synthesis Using Normalising Flows
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Automatic synthesis of realistic gestures promises to transform the fields of animation, avatars and communicative agents. In off-line applications, novel tools can alter the role of an animator to that of a director, who ...
Expression Packing: As-Few-As-Possible Training Expressions for Blendshape Transfer
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
To simplify and accelerate the creation of blendshape rigs, using a template rig is a common procedure, especially during the creation of digital doubles. Blendshape transfer methods facilitate copy and paste functionality ...
