Dynamic facial expression recognition with a discrete choice model

Michel Bierlaire, Javier Cruz Mota, Thomas Robin

We propose a dynamic facial expression recognition framework based on discrete choice models (DCM). We model the choice of a person who has to label a video sequence representing a facial expression. The originality is based on the explicit modeling of cau ...

BOLD responses to trigeminal nerve stimulation

Rolf Gruetter, Carl Petersen, Nathalie Just

The current study investigates a new model of barrel cortex activation using stimulation of the infraorbital branch of the trigeminal nerve. A robust and reproducible activation of the rat barrel cortex was obtained following trigeminal nerve stimulation. ...

View-Based Appearance Model Online Learning for 3D Deformable Face Tracking

Jean-Marc Odobez, Stephanie Lefèvre

In this paper we address the issue of joint estimation of head pose and facial actions. We propose a method that can robustly track both subtle and extreme movements by combining two types of features: structural features observed at characteristic points ...

A 3-D Audio-Visual Corpus of Affective Communication

Communication between humans deeply relies on the capability of expressing and recognizing feelings. For this reason, research on human-machine interaction needs to focus on the recognition and simulation of emotional states, prerequisite of which is the c ...

Modelling human perception of facial expressions

Michel Bierlaire, Jean-Philippe Thiran, Matteo Sorci, Javier Cruz Mota, Thomas Robin

Facial expression recognition by human observers is affected by subjective components. Indeed there is no ground truth. We have developped Discrete Choice Models to capture the human perception of facial expressions. In a first step, the static case is tre ...

Automatic facial expression recognition: a discrete choice approach

Michel Bierlaire

Automatic facial expression recognition finds applications in various fields where human-machine interactions are involved. We propose a framework based on discrete choice models, where we try to forecast how a human person would evaluate the facial expres ...

Pointing with the eyes: The role of gaze in communicating danger

Nouchine Hadjikhani

Facial expression and direction of gaze are two important sources of social information, and what message each conveys may ultimately depend on how the respective information interacts in the eye of the perceiver. Direct gaze signals an interaction with th ...

Modelling human perception of static facial expressions

Michel Bierlaire, Jean-Philippe Thiran, Matteo Sorci, Gianluca Antonini, Javier Cruz Mota, Barbara Cerretani

Data collected through a recent web-based survey show that the perception (i.e. labeling) of a human facial expression by a human observer is a subjective process, which results in a lack of a unique ground-truth, as intended in the standard classification ...

A Web Survey for Facial Expressions Evaluation

Michel Bierlaire, Jean-Philippe Thiran, Matteo Sorci, Gianluca Antonini

In the recent years, researchers have investigated several methods of facial expression analysis. Their interest has been to apply their algorithms to sets of images labelled by a restrained number of experts. In order to deal with the generalizability of ...
