Human-Brain Interface: Signal Processing and Machine Learning

Touradj Ebrahimi, Ulrich Hoffmann

The Electroencephalogram (EEG) is a recording of the electrical potentials generated by brain activity on the scalp. It has been used for decades as a non-invasive tool both in fundamental brain research and in clinical diagnosis. But it is now widely used ...

Microfabrique

Irène Verettas

Since 1990 in Japan and the last years in Europe, the concept of small assembly lines called Microfactories is under investigation. The main goal of this thesis is to establish a methodology for a quick setup of a miniature and modular assembly line. This ...

Localisation de Visages par Boosting de Classificateurs Lineaires

Jean-Philippe Thiran, Julien Meynet

Dans ce rapport, une methode pour la localisation de visages est presentee. La localisation de visages est une des composantes importantes dans l analyse et la comprehension de visages. Les methodes existantes pour localiser des visages peuvent etre subdiv ...

Writer Identification for Smart Meeting Room Systems

Samy Bengio, Jonas Richiardi

In this paper we present a text independent on-line writer identification system based on Gaussian Mixture Models (GMMs). This system has been developed in the context of research on Smart Meeting Rooms. The GMMs in our system are trained using two sets of ...

A Thousand Words in a Scene

Daniel Gatica-Perez, Jean-Marc Odobez, Pedro Manuel Da Silva Quelhas

This paper presents a novel approach for visual scene modeling and classification, investigating the combined use of text modeling methods and local invariant features. Our work attempts to elucidate (1) whether a text-like \emph{bag-of-visterms} represent ...

Multimedia event modelling and recognition

Mark Barnard

The recognition of events in multimedia data is a challenging area of research. The growth in the amount of multimedia data being produced and stored increases the need for systems capable of automatically analysing this data. This analysis can aid in effi ...

Local Binary Patterns as an Image Preprocessing for Face Authentication

Sébastien Marcel, Guillaume Heusch, Yann Rodriguez

One of the major problem in face authentication systems is to deal with variations in illumination. In a \mbox{realistic} scenario, it is very likely that the lighting conditions of the probe image does not correspond to those of the gallery image, hence t ...

Spectral Entropy Feature in Multi-stream for Robust ASR

Hervé Bourlard, Hemant Misra

In recent papers, entropy computed from sub-bands of the spectrum was used as a feature for automatic speech recognition. In the present paper, we further study the sub-band spectral entropy features which can give the flatness/peakiness of the sub-band sp ...

Three-Dimensional Feature Detection Using Optimal Steerable Filters

Michaël Unser, François Aguet, Mathews Jacob

We present a framework for feature detection in 3-D using steerable filters. These filters can be designed to optimally respond to a particular type of feature by maximizing several Canny-like criteria. The detection process involves the analytical computa ...

Face Detection with Mixtures of Boosted Discriminant Features

Jean-Philippe Thiran, Vlad Popovici, Julien Meynet

Detecting faces in images is a key step in numerous computer vision applications as face recognition for example. Face detection is a difficult task in image analysis because of the large face intra-class variability which is due to the important influence ...
