Asymmetrical Facial Expressions based on an Advanced Interpretation of Two-dimensional Russells Emotional Model

Daniel Thalmann, Stéphane Gobron, Junghyun Ahn, Quentin Silvestre

This paper proposes a novel method to compute emotional parameters based on Russell's 2D circumplex diagram for simulating and visualizing asymmetric facial expressions. Based on a large set of emotion coordinates allocated by psychologists, we have select ...

From Sentence to Emotion: a real-time 3D graphics metaphor of emotions extracted from text

Daniel Thalmann, Stéphane Gobron, Junghyun Ahn

This paper presents a novel concept: a graphical representation of human emotion extracted from text sentences. The major contributions of this paper are the following. First, we present a pipeline that extracts, processes, and renders emotion of 3D virtua ...

Sentiment analysis of informal textual communication in cyberspace

Daniel Thalmann, Stéphane Gobron

The ability to correctly identify the existence and polarity of emotion in informal, textual communication is a very important part of a realistic and immersive 3D environment where people communicate with one another through avatars or with an automated s ...

GPU Accelerated Computation and Visualisation of Hexagonal Cellular Automata

Stéphane Gobron

We propose a graphics processor unit (GPU)-accelerated method for real-time computing and rendering cellular automata (CA) that is applied to hexagonal grids. Based on our previous work –which introduced first and second dimensional cases– this paper prese ...

Retina Simulation using Cellular Automata and GPU Programming

Stéphane Gobron

This article shows how the architecturalmod- elization of biological retina allows real-time performances on cheap and widespread computing systems. Firstly we describe the biological retina in terms of its pipeline ar- chitecture detailing its layer behav ...

Information Visualization of Multi-dimensional Cellular Automata using GPU Programming

Stéphane Gobron

We propose a method for generating all possible rules of multidimension Boolean cellular automata (CA). Based on an original encoding method and the programming of graphical processor units (GPU), this method allows us to visualize the CA information flow ...

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 ...

Generating Surface Textures based on Cellular Networks

Stéphane Gobron

This paper describes a method allowing the automatic multi-texturing and simulation of surface imperfections based on a cellular network. In this representation, networks of connected cells are constructed in a natural and dynamic way allowing simultaneous ...

Interactive three-dimensional reconstruction and weathering simulations on buildings

Stéphane Gobron

Architectural sites suffers from weathering effects such as liquid sedimentation, lampblack or pollution deposit, moss growing or longterm erosion. Displaying their impact on present buildings could help deciders to plan relevant actions for preserving the ...
