Human emotion distribution has been regarded as an important part of emotional geography research. However, it is difficult to form a global scaled map reflecting human emotions at the same sampling density because various emotional sampling data are usually positive occurrences without absence data. In this study, a methodological framework for mapping the global geographic distribution of human emotion is proposed and applied, combining a species distribution model with physical environment factors. State-of-the-art affective computing technology is used to extract human emotions from facial expressions in Flickr photos. Various human emotions are considered as different species to form their ‘habitats’ and predict the suitability, termed as ‘Emotional Habitat’. To our knowledge, this framework is the first method to predict emotional distribution from an ecological perspective. Different geographic distributions of seven dimensional emotions are explored and depicted, and emotional diversity and abnormality are detected at the global scale. These results confirm the effectiveness of our framework and offer new insights to understand the relationship between human emotions and the physical environment. Moreover, our method facilitates further rigorous exploration in emotional geography and enriches its content.

Simultaneous Facial Action Tracking and Expression Recognition in the Presence of Head Motion / Fadi Dornaika in International journal of computer vision, vol 76 n°3 (March 2008)  

Public [article]  inInternational journal of computer vision > vol 76 n°3 (March 2008) . - pp 257 - 281 Titre : Simultaneous Facial Action Tracking and Expression Recognition in the Presence of Head Motion Type de document : Article/Communication Auteurs : Fadi Dornaika , Auteur ; Franck Davoine, Auteur Année de publication : 2008 Article en page(s) : pp 257 - 281 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Traitement d'image optique [Termes IGN] reconnaissance faciale Résumé : (auteur) The recognition of facial gestures and expressions in image sequences is an important and challenging problem. Most of the existing methods adopt the following paradigm. First, facial actions/features are retrieved from the images, then the facial expression is recognized based on the retrieved temporal parameters. In contrast to this mainstream approach, this paper introduces a new approach allowing the simultaneous retrieval of facial actions and expression using a particle filter adopting multi-class dynamics that are conditioned on the expression. For each frame in the video sequence, our approach is split into two consecutive stages. In the first stage, the 3D head pose is retrieved using a deterministic registration technique based on Online Appearance Models. In the second stage, the facial actions as well as the facial expression are simultaneously retrieved using a stochastic framework based on second-order Markov chains. The proposed fast scheme is either as robust as, or more robust than existing ones in a number of respects. We describe extensive experiments and provide evaluations of performance to show the feasibility and robustness of the proposed approach.

Dynamic vs. Static recognition of facial expressions / Bogdan Raducanu (2008)  

Public Titre : Dynamic vs. Static recognition of facial expressions Type de document : Article/Communication Auteurs : Bogdan Raducanu, Auteur ; Fadi Dornaika , Auteur Editeur : Berlin, Heidelberg, Vienne, New York, ... : Springer Année de publication : 2008 Collection : Lecture notes in Computer Science, ISSN 0302-9743 num. 5355 Conférence : AmI 2008, 2nd European Conference on Ambient Intelligence 19/11/2008 22/11/2008 Nuremberg Allemagne Importance : pp 13 - 25 Format : 16 x 24 cm Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Traitement d'image optique [Termes IGN] intelligence artificielle [Termes IGN] reconnaissance faciale [Termes IGN] robotique [Termes IGN] série temporelle Résumé : (auteur) In this paper, we address the dynamic recognition of basic facial expressions. We introduce a view- and texture independent schemes that exploits facial action parameters estimated by an appearance-based 3D face tracker. We represent the learned facial actions associated with different facial expressions by time series. Furthermore, we compare this dynamic scheme with a static one and show that the former performs better than the latter. We provide evaluations of performance using several classification schemes. With the proposed scheme, we developed an application for social robotics, in which an AIBO is mirroring the facial expression recognized.

Efficient facial expression recognition for human robot interaction / Fadi Dornaika (2007)  

Public Titre : Efficient facial expression recognition for human robot interaction Type de document : Article/Communication Auteurs : Fadi Dornaika , Auteur ; Bogdan Raducanu, Auteur Editeur : Berlin, Heidelberg, Vienne, New York, ... : Springer Année de publication : 2007 Collection : Lecture notes in Computer Science, ISSN 0302-9743 num. 4507 Conférence : IWANN 2007, 9th International Work-Conference on Artificial Neural Networks 20/06/2007 22/06/2007 San Sebastian Espagne Importance : pp 700 - 708 Format : 16 x 24 cm Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Traitement d'image [Termes IGN] interaction homme-machine [Termes IGN] reconnaissance faciale [Termes IGN] robot [Termes IGN] vision par ordinateur Résumé : (auteur) In this paper, we propose a novel approach for facial expression analysis and recognition. The main contributions of the paper are as follows. First, we propose an efficient facial expression recognition scheme based on the detection of keyframes in videos where the recognition is performed using a temporal classifier. Second, we use the proposed method for extending the human-machine interaction functionality of the AIBO robot. More precisely, the robot is displaying an emotional state in response to the recognized user's facial expression. Experiments using unseen videos demonstrated the effectiveness of the developed method.
