System and method for projecting images through scattering media

Demetri Psaltis, Christophe Moser, Babak Rahmani

The invention discloses a system (1) and method to guide light through a scattering medium (4) and project images on a screen (5) placed after the medium (4). Many of the shortcomings of previous approaches for guiding light through scattering medium (4) h ...

Epitome - A Social Game for Photo Album Summarization

Touradj Ebrahimi, Jong Seok Lee, Ivan Ivanov, Péter Vajda

In this paper, we propose an approach for photo album summarization through a novel social game "Epitome" for mobile phones. Our approach to album summarization consists of two games: "Select the Best!" and "Split it!". The goal of the first game is to all ...

Recognizing Human Visual Focus of Attention from Head Pose in Meetings

Jean-Marc Odobez, Silèye Oumar Ba

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 ...

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 ...
