Model-based 3D Face Reconstruction

The human face plays an essential role in social interactions as it brings information about someone's identity, state of mind, or mood. People are, by nature, very good at catching this non-spoken information. Therefore, scientists have been interested in ...

ExprADA: Adversarial domain adaptation for facial expression analysis

Jean-Philippe Thiran, Seyedbehzad Bozorgtabar

We propose a deep neural network based image-to-image translation for domain adaptation, which aims at finding translations between image domains. Despite recent GAN based methods showing promising results in image-to-image translation, they are prone to f ...

Using Photorealistic Face Synthesis and Domain Adaptation to Improve Facial Expression Analysis

Jean-Philippe Thiran, Mohammad Saeed Rad, Hazim Kemal Ekenel

Cross-domain synthesizing realistic faces to learn deep models has attracted increasing attention for facial expression analysis as it helps to improve the performance of expression recognition accuracy despite having small number of real training images. ...

Context-Aware Emotion Recognition Networks

Seungryong Kim, Jiyoung Lee

Traditional techniques for emotion recognition have focused on the facial expression analysis only, thus providing limited ability to encode context that comprehensively represents the emotional responses. We present deep networks for context-aware emotion ...

Put on that colour, it fits your emotion: Colour appropriateness as a function of expressed emotion

Christine Mohr, Cynthia Marchand

People associate affective meaning with colour, and this may influence decisions about colours. Hue is traditionally considered the most salient descriptor of colour and colour-affect associations, although colour brightness and saturation seem to have par ...

A Wearable Camera Detects Gaze Peculiarities during Social Interactions in Young Children with Pervasive Developmental Disorders

Aude Billard, Basilio Noris, Patrick Jermann, Silvia Magrelli

We report on the study of gazes, conducted on children with pervasive developmental disorders (PDD), by using a novel head-mounted eye-tracking device called the WearCam. Due to the portable nature of the WearCam, we are able to monitor naturalistic intera ...

Asymmetric facial expressions: revealing richer emotions for embodied conversational agents

Daniel Thalmann, Ronan Boulic, Stéphane Gobron, Junghyun Ahn

In this paper, we propose a method to achieve effective facial emotional expressivity for embodied conversational agents by considering two types of asymmetry when exploiting the Valence-Arousal-Dominance representation of emotions. Indeed, the asymmetry o ...

Conveying Real-Time Ambivalent Feelings through Asymmetric Facial Expressions

Daniel Thalmann, Ronan Boulic, Junghyun Ahn, Stéphane Gobron

Achieving effective facial emotional expressivity within a real-time rendering constraint requests to leverage on all possible inspiration sources and especially from the observations of real individuals. One of them is the frequent asymmetry of facial exp ...

An Interdisciplinary VR-Architecture for 3D Chatting with Non-verbal Communication

Daniel Thalmann, Junghyun Ahn, Stéphane Gobron, Quentin Silvestre

The communication between avatar and agent has already been treated from different but specialized perspectives. In contrast, this paper gives a balanced view of every key architectural aspect: from text analysis to computer graphics, the chatting system a ...

Sizing of riprap for spill-through abutments

Anton Schleiss, António Heleno Cardoso

An experimental investigation of riprap stability at spill-through abutments has been carried out in two similar horiontal-bed flumes, avoiding riprap failure modes other than shear failure and erosion failure. Tests were conducted for two common abutment ...

Automatic face analysis in static and dynamic environments

Matteo Sorci

Faces play a vital role in people's daily lives, as they are able to convey many different information and above all their behaviour and emotions. Therefore, for decades the face has been investigated by researchers in several fields such as computer scien ...

3D Spectral Nonrigid Registration of Facial Expression Scans

Jean-Philippe Thiran, Hazim Kemal Ekenel, Gabriel Louis Cuendet, Christophe René Joseph Ecabert, Marina Zimmermann

In this paper, we introduce a new template-based spectral nonrigid registration method in which the target is represented using multilevel partition of unity (MPU) implicit surfaces and the template is embedded in a discrete Laplace-Beltrami based spectral ...
