Détection de la dépression par l’analyse de la géométrie faciale et de la parole

2017

Depression is one of the most prevalent mental disorders, burdening many people world-wide. A system with the potential of serving as a decision support system is proposed, based on novel features extracted from facial expression geometry and speech, by interpreting non-verbal manifestations of depression. The proposed system has been tested both in gender independent and gender based modes, and with different fusion methods. The algorithms were evaluated for several combinations of parameters and classification schemes, on the dataset provided by the Audio/Visual Emotion Challenge of 2013 and 2014. The proposed framework achieved a precision of 94.8% for detecting persons achieving high sc…

National Migration in rural Germany -A complex network perspective on interdependencies for elderly migration and well-being

2022

Spatial planning decisions have to consider complex networks of influences in order to deliver sustainable results. For example, the construction of a retirement home may cause older people to migrate from the aging single-family home areas (SFHA) in the surrounding region.The answer to the question if and where to migrate is an individual human decision and thus depends not only on the surrounding circumstances and influences but also on the experiencesand knowledge every individual has. Therefore, the analysis has to incorporate data on the influences as well as data on the individual subjects as well. There are several approaches inthe field of well-being and quality of life research. Th…

Graphes multicouches pour mesurer la similarité entre des films

2022

Un système de recommandation des films propose à ses utilisateurs un ensemble de films similaires à leurs séries préférées, en se basant sur le principe de filtration, par exemple la filtration de leurs données personnelles. Ces dernières années, les réseaux sociaux sont devenus de plus en plus utilisés pour représenter et analyser des histoires de films[1][2][3]. Une étude [6] s'est appuyée sur les réseaux sociaux pour classifier les films par genre. D'autres études [4][5] ont utilisé les réseaux sociaux pour analyser des films à partir des rôles des personnages. A notre connaissance, il n'existe pas une technique qui permet de trouver la similarité entre deux films en calculant la distanc…

Analyse du mouvement d'un objet déformable décrit par une série de nuages de points

2012

Ce rapport technique a pour but de mettre en forme nos démarches de recherche concernant le sujet de post-doctorat qui m'a été proposé, celui-ci ayant trait au suivi (tracking ) de formes en mouvement. Je mets ici en évidence, d'une part, les buts que nous souhaitons concrètement atteindre, et d'autre part, les principales contraintes techniques qui leurs sont liées. Ces contraintes ont un rapport direct avec les données que nous traitons : les nuages de points. J'exposerai une méthode développée dans le but de répondre à cette problématique, en la situant par rapport au travail existant en suivi de forme. Enfin, je proposerai un ensemble de discussions ayant trait à la poursuite de ce trav…

Hand Gestures Recognition and Tracking

2013

In this project we develop a system that uses low cost web cameras to recognise gestures and track 2D orientations of the hand. This report is organized as such. First in section 2 we introduce various methods we undertook for hand detection. This is the most important step in hand gesture recognition. Results of various skin detection algorithms are discussed in length. This is followed by region extraction step (section 3). In this section approaches like contours and convex hull to extract region of interest which is hand are discussed. In section 4 a method is describe to recognize the open hand gesture. Two additional gestures of palm and fist are implemented using Haar-like features. …
