Recognizing Human Visual Focus of Attention from Head Pose in Meetings

We address the problem of recognizing the visual focus of attention (VFOA) of meeting participants based on their head pose. To this end, the head pose observations are modeled using a Gaussian Mixture Model (GMM) or a Hidden Markov Model (HMM) whose hidde ...

Display system and method using a projector and a reflective display

Sabine Süsstrunk

A display system comprising a reflective display configured to display a luminance component associated with a color input signal and a projector configured to project a chrominance component associated with the color input signal onto the reflective displ ...

Selected topics on distributed video coding

Mourad Ouaret

Distributed Video Coding (DVC) is a new paradigm for video compression based on the information theoretical results of Slepian and Wolf (SW), and Wyner and Ziv (WZ). While conventional coding has a rigid complexity allocation as most of the complex tasks a ...

A Cognitive and Unsupervised MAP Adaptation Approach to the Recognition of the Focus of Attention from Head Pose

Jean-Marc Odobez, Silèye Oumar Ba

In this paper, the recognition of the visual focus of attention (VFOA) of meeting participants (as defined by their eye gaze direction) from their head pose is addressed. To this end, the head pose observations are modeled using an Hidden Markov Model (HMM ...

Recognizing People's Focus of Attention from Head Poses: a Study

Jean-Marc Odobez, Silèye Oumar Ba

This paper presents a study on the recognition of the visual focus of attention (VFOA) of meeting participants based on their head pose. Contrary to previous studies on the topic, in our set-up, the potential VFOA of a person is not restricted to other mee ...

Multimodal authoring tool for populating a database of emotional reactive animations

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

We aim to create a model of emotional reactive virtual humans. This model will help to define realistic behavior for virtual characters based on emotions and events in the virtual environment to which they react. A large set of pre-recorded animations will ...

The mobile animator: interactive character animation in collaborative virtual environments

Daniel Thalmann, Frédéric Vexo

We have designed a mobile -PDA-based- interface for real-time control of virtual characters in multiuser semi-immersive virtual environments - using a large rear-projection screen. The proof-of-concept implementation we present shows the potential of handh ...

Conducting a virtual orchestra

Daniel Thalmann, Frédéric Vexo, Sébastien Schertenleib

The virtual orchestra is a multimodal system architecture based on complex 3D sound environment processing and a compact user interface. The system architecture supports high-performance sound content for VR (virtual reality) applications, and the user con ...

Automatic Calibration of a Structured Light System for Generation and Registration of 3D Surface Models

Roland Siegwart, Charles Baur, Oussama Khatib

This project explores a new approach in the automatic calibration of a structured light system without need of prior knowledge neither on the intrinsic or extrinsic parameters of the camera and projector, nor on the environment. ...
