Motion Integration in Visual Attention Models for Predicting Simple Dynamic Scenes

Heinz Hügli, Alexandre Bur

Visual attention models mimic the ability of a visual system, to detect potentially relevant parts of a scene. This process of attentional selection is a prerequisite for higher level tasks such as object recognition. Given the high relevance of temporal a ...

3D Hand Model Fitting for Virtual Keyboard System

Edoardo Charbon, Huan Du

In this paper, a 3D hand model fitting method is presented which can recover the accurate finger positions for a virtual keyboard system. The 3D hand model consists of a detailed polygonal skin driven by an underlying skeleton system. The system uses a str ...

An action selection architecture for autonomous virtual humans in persistent worlds

Etienne De Sevin

Nowadays, virtual humans such as non-player characters in computer games need to have a strong autonomy in order to live their own life in persistent virtual worlds. When designing autonomous virtual humans, the action selection problem needs to be conside ...

Merging Cellular Automata for Simulating Surface Effects

Stéphane Gobron

This paper describes a model of three-dimensional cellular automata allowing to simulate different phenomena in the fields of computer graphics or image processing. Our method allows to combine them together in order to produce complex effects such as auto ...

Images incorporating microstructures

Roger Hersch

A method of generating an image incorporating a microstructure includes the steps of obtaining an original image, generating a microstructure, and rendering a region or the whole said original image with said microstructure. The operation of generating the ...

Organic shape modeling through haptic devices

Daniel Thalmann, Frédéric Vexo, Renaud Ott

This paper presents a sketching system for 3D organic shapes modeling and animation using virtual reality devices. On the hardware side, it is based on the Haptic Workstation™ which conveys force feedback on the user arms (upper body limbs), and a head mou ...

Mixing virtual and real scenes in the site of ancient Pompeii

Daniel Thalmann, Sébastien Schertenleib

This paper presents an innovative 3D reconstruction of ancient fresco paintings through the real-time revival of their fauna and flora, featuring groups of virtual animated characters with artificial-life dramaturgical behaviours in an immersive, fully mob ...

Which Colors Best Catch Your Eyes: a Subjective Study of Color Saliency

Touradj Ebrahimi, Elisa Drelie Gelasca

To determine Regions of Interest (ROI) in a scene, percep-tual saliency of regions has to be measured. When scenes are viewed with the same context and motivation, these ROIs are often highly correlated among different people. As a result, it is possible t ...

Tracking People in Meetings with Particles

Daniel Gatica-Perez, Jean-Marc Odobez, Guillaume Lathoud, Silèye Oumar Ba, Kevin Smith

Automatic meeting analysis is an emerging research field. In this paper, we present stochastic algorithms for tracking people in multi-sensor meeting rooms, for a number of relevant tasks, including tracking multiple people, tracking head pose towards anal ...
