Realtime Face Tracking and Animation

Sofien Bouaziz

Capturing and processing human geometry, appearance, and motion is at the core of computer graphics, computer vision, and human-computer interaction. The high complexity of human geometry and motion dynamics, and the high sensitivity of the human visual sy ...

The DHLAB Trajectory

Alexandre André Robert Rigal, Dario Rodighiero, Loup Cellard

This visualisation represents the research activity of the Digital Humanities Lab through publications and co-authorship. Vertical disposition is ordered by time: each layer is a different year of publications, from the lab’s foundation to nowadays. The la ...

Dynamic 3D Avatar Creation from Hand-held Video Input

Mark Pauly, Sofien Bouaziz, Alexandru Eugen Ichim

We present a complete pipeline for creating fully rigged, personalized 3D facial avatars from hand-held video. Our system faithfully recovers facial expression dynamics of the user by adapting a blendshape template to an image sequence of recorded expressi ...

MATHICSE Technical Report : Low-rank tensor approximation for high-order correlation functions of Gaussian random fields

Fabio Nobile, Daniel Kressner, Christine Tobler, Rajesh Kumar

Gaussian random fields are widely used as building blocks for modeling stochastic processes. This paper is concerned with the efficient representation of d-point correlations for such fields, which in turn enables the representation of more general stochas ...

Representation of Medical Guidelines with a Computer Interpretable Model

Giovanni De Micheli, Alena Simalatsar, Wenqi You Dubout

Nowadays medical software is tightly coupled with medical devices that perform patient state monitoring and lately even some basic treatment procedures. Medical guidelines (GLs) can be seen as specification of a medical system which requires their computer ...

A clustering-based method to estimate saliency in 3D animated meshes

Mahmut Sami Arpa

We present a model to determine the perceptually significant elements in animated 3D scenes using a motion-saliency method. Our model clusters vertices with similar motion-related behaviors. To find these similarities, for each frame of an animated mesh se ...

Online Modeling For Realtime Facial Animation

Mark Pauly, Sofien Bouaziz

We present a new algorithm for realtime face tracking on commodity RGB-D sensing devices. Our method requires no user-specific training or calibration, or any other form of manual assistance, thus enabling a range of new applications in performance-based f ...

Prony Series Representation for the Lightning Channel Base Current

In this paper, a new representation for the lightning channel base current is proposed in terms of the so-called Prony series, obtained by means of a modified time-domain variant of the well-known vector fitting technique. This method allows both to reprod ...

Learning to use novel objects: A training study on the acquisition of novel action representations

Michiel van Elk, Christian Pfeiffer

Many studies have suggested that the motor system is organized in a hierarchical fashion, around the prototypical end location associated with using objects. However, most studies supporting the hierarchical view have used well-known actions and objects th ...
