Person Independent 3D Facial Expression Recognition by a Selected Ensemble of SIFT Descriptors
No full textFacial expression recognition has been addressed mainly working on 2D images or videos. In this paper, the problem of person-independent facial expression recognition is addressed on 3D shapes. To this end, an original approach is proposed that relies on selecting the minimal-redundancy maximal-relevance features derived from a pool of SIFT feature descriptors computed in correspondence with facial landmarks of depth images. Training a Support Vector Machine for every basic facial expression to be recognized, and combining them to form a multiclass classifier, an average recognition rate of 77.5% on the BU-3DFE database has been obtained. Comparison with competitors approaches using a common experimental setting on the BU-3DFE database, shows that our solution is able to obtain state of the art results.Eurographics Workshop on 3D Object Retrieva
Joint ACM workshop on human gesture and behavior understanding (J-HGBU'11)
No full textThe ability to understand social signals of a person we are communicating with is the core of social intelligence. Social Intelligence is a facet of human intelligence that has been argued to be indispensable and perhaps the most important for success in life. At the same time, human-centric multimedia applications for humans and about humans are becoming increasingly important. 3D modeled human-objects, like bodies, heads and faces are exploited for animation, security, and human computer interaction, while three dimensional motion of arms, legs and local body features is used for more complete human gesture, activity and behavior analysis. The Joint Human Gesture and Behavior Understanding (J-HGBU) workshop event consists of two parts focusing on these complementary challenges: the Workshop on Multimedia Access to 3D Human Objects (MA3HO'11) and the Workshop on Social Signal Processing (SSPW'11). © 2011 ACM
Imam Ahmad Daoudi Trabelsi (402 h) and his enhancing contributions in the printed, manuscript and missing science of Hadith
No full textImam al-Daoudi has a well-known and respectful reputation among scholars in the field of
Alsharia’ah. He is the first to explain Al-Bukhari's book, presenting a creative renovation method
in interpreting its content chapters. He was not just a word-conveyed person, as the case in many
interpreters, instead, his interpretations were remarkably categorized with unique characteristics.
The most of junior Imams of modernists had done a tremendous of citation of his interpretations.
Daoudi had lived in Tripoli, the west (Libya), where it was a center of science at that time. Those
who are interested in having deeper knowledge about the efforts of libyan scientists can get their
desire fully satisfied about the knowledge of Sheikh Imam al-Daoudi’s efforts and his enrich
enhancing contributions in the science of Al-hadith only after a great effort. Therefore, this
researcher is conducted in order to reveal about the contributing heritage of Sheikh Imam alDaoudi, shedding light on his hard printed manuscripts particularly the lost ones. Thus, this
qualitative research depends on the analytical descriptive approach, which led to the following
results: The Imam Daoudi in one of the leading scientists of Al-Hadith how did well considerable
critique research studies in order to evaluate the credibility and validity of the Hadith phrases
presented in Al-Bukhari's book and one of the scientists who protected this book. Besides, his
written works (books) have possessed a well-trusted referential status among other publications
in this field. He is one of the seniors who wrote about the Islamic financial economics. More
interestingly, he was the first who interpreted Al-Bukhari's book in the Islamic Maghreb region.
His publications were a magnificent collection that consisted of a printed books, manuscripts and
missing manuscripts
Blocking Adult Images Based on Statistical Skin Detection
No full textThis work is aimed at the detection of adult images that appear in Internet. Skin detection is of the paramount importance in the detection of adult images. We build a maximum entropy model for this task. This model, called the First Order Model in this paper, is subject to constraints on the color gradients of neighboring pixels. Parameter estimation as well as optimization cannot be tackled without approximations. With Bethe tree approximation, parameter estimation is eradicated and the Belief Propagation algorithm permits to obtain exact and fast solution for skin probabilities at pixel locations. We show by the Receiver Operating Characteristics (ROC) curves that our skin detection improves the performance in the previous work in the context of skin pixel detecton rate and false positive rate. The output of skin detection is a grayscale skin map with the gray level indicating the belief of skin. We then calculate 9 simple features from this map which form a feature vector. We use the fit ellipses to catch the characteristics of skin distribution. Two fit ellipses are used for each skin map---the fit ellipse of all skin regions and the fit ellipse of the largest skin region. They are called respectively Global Fit Ellipse and Local Fit Ellipse in this paper. A multi-layer perceptron classifier is trained for these features. Plenty of experimental results are presented including photographs and a ROC curve calculated over a test set of 5,084 photographs, which show stimulating performance for such simple features
LE E-LEARNING POUR GENERALISER LES TICs AU MAROC
No full textLa dernière décennie du 20° siècle a été marquée par le développement spectaculaire des TICs, ce qui a conduit à un bouleversement dans les modes de communication et de diffusion de l'information. Le Maroc ayant la volonté de s'inscrire dans la société de l'information et du savoir a opté pour la stratégie e-Maroc, proposant une vision globale permettant la réduction de la fracture numérique qui le sépare des pays développés. En parallèle, il a lancé l'Initiative Nationale de Développement Humain (INDH) visant l'amélioration des conditions de vie des marocains, en favorisant l'élargissement des choix des personnes et en minimisant la disparité dans tous les domaines. Cependant, la mise en place du projet e-Maroc ne peut voir le jour en présence de pourcentages importants d'analphabètes en TICs, aussi bien dans l’administration publique que dans les universités, et qui s’accentuent, d’une année à l’autre, en l'absence de stratégies et d'infrastructures d'intégration de ces technologies dans la formation dans le cursus de l’ensemble des spécialités et dans la formation continue. Il en est de même pour le projet INDH. Il faut veiller à combler la disparité technologique qui existe entre les zones rurales et urbaines, entre ministères et collectivités locales ou centres régionaux et enfin entre l’ensemble des citoyens qui n’ont pas les mêmes compétences leur permettant d'élargir leurs choix. Dans ce contexte, la généralisation des TICs est devenue un besoin et une finalité. 164 Daoudi Najima Or, cette tache s’avére difficile, en raison de I’insuffisance de compétences en TICs et du manque d’encadrement a tous les niveaux d’enseignement et, plus particulièrement, dans les universités et les écoles supérieures, aggravés par le départ volontaire, notamment des professeurs, et par le manque d'infrastructures et d'équipements indispensables. Parmi les solutions à l’ordre du jour, il y a le « e-learning ». I s’agit d’un nouveau mode de transmission des contenus pédagogiques des formations à travers les technologies de l'information et de la communication
Chronic posterior fracture-dislocation of the shoulder: case report and a literature review
No full textPosterior shoulder fracture-dislocation is a rareinjury accounting for approximately 0.9% ofshoulder fracture-dislocations and oftenmisdiagnosed during the initial presentation to aphysician.

Computer Vision in Human Analysis: From Face and Body to Clothes
No full textFor decades, researchers of different areas, ranging from artificial intelligence to computer vision, have intensively investigated human-centered data, i.e., data in which the human plays a significant role, acquired through a non-invasive approach, such as cameras. This interest has been largely supported by the highly informative nature of this kind of data, which provides a variety of information with which it is possible to understand many aspects including, for instance, the human body or the outward appearance. Some of the main tasks related to human analysis are focused on the body (e.g., human pose estimation and anthropocentric measurement estimation), the hands (e.g., gesture detection and recognition), the head (e.g., head pose estimation), or the face (e.g., emotion and expression recognition). Additional tasks are based on non-corporal elements, such as motion (e.g., action recognition and human behavior understanding) and clothes (e.g., garment-based virtual try-on and attribute recognition). Unfortunately, privacy issues severely limit the usage and the diffusion of this kind of data, making the exploitation of learning approaches challenging. In particular, privacy issues behind the acquisition and the use of human-centered data must be addressed by public and private institutions and companies.
Thirteen high-quality papers have been published in this Special Issue and are summarized in the following: four of them are focused on the human face (facial geometry, facial landmark detection, and emotion recognition), two on eye image analysis (eye status classification and 3D gaze estimation), five on the body (pose estimation, conversational gesture analysis, and action recognition), and two on the outward appearance (transferring clothing styles and fashion-oriented image captioning). These numbers confirm the high interest in human-centered data and, in particular, the variety of real-world applications that it is possible to develop
L'enchaînement question-réponse dans une enquête sur la dénomination des couleurs
No full textWald Paul, Abderrahim Daoudi et Kamila Sefta - "Linking a question with answers in an inquiry on colour naming".
Linking a question with answers is examined in the discursive treatment of the question by the response-act. This treatment appears as the validation of the thematic and formal closures introduced by the questioning which draws the limits of the discourse activity to be performed. These relationships were studied in the answers of 44 subjects, naming a set of ambigous colors (in Moroccan Arabic) in an academic setting, under several interrogation conditions. The corpuses obtained in each condition were described and compared from the point of view of "natural answer" frequency, e.g. frequency of answers validating the closures through their formal and thematic adequacy to the response model constrained by the question.L'enchaînement question-réponse est examiné sous l'angle de la prise en charge de la question par l'acte de répondre. Cet effet se manifeste par la validation, dans la réponse, des clôtures thématique et formelle qui délimitent l'activité discursive initiée par l'interrogation. Ces rapports sont étudiés dans les réponses de dénomination (en arabe marocain) d'une collection de couleurs ambiguës par 44 sujets en situation scolaire, répondant dans des conditions d'interrogation différentes à la même question. Les corpus obtenus dans les diverses conditions sont caractérisés et comparés entre eux par la fréquence des réponses naturelles, validant les clôtures de l'interrogation introduites par la formulation de la question.Wald Paul, Daoudi Abderrahim, Sefta Kamila.
