Hippocampal volume reduction in 22q11.2 deletion syndrome

Marie Schaer

Hippocampal volume reduction and decreased memory skills form a characteristic neurofunctional alteration observed in schizophrenia. Individuals affected with 22q11.2 deletion syndrome (22q11DS), while exhibiting memory deficits throughout development, are ...

Speech Enhancement and Recognition in Meetings with an Audio-Visual Sensor Array

Daniel Gatica-Perez

We address the problem of distant speech acquisition in multi-party meetings, using multiple microphones and cameras. Microphone array beamforming techniques present a potential alternative to close-talking microphones by providing speech enhancement throu ...

Mutual information eigenlips for audio-visual speech recognition

Jean-Philippe Thiran, Ivana Arsic de Heras Ciechomska

This paper proposes an application of information theoretic approach for finding the most informative subset of eigenfeatures to be used for audio-visual speech recognition tasks. The state-of-the-art visual feature extraction methods in the area of speech ...

Measuring the Performance of Face Localization Systems

Samy Bengio, Yann Rodriguez

The purpose of Face localization is to determine the coordinates of a face in a given image. It is a fundamental research area in computer vision because it serves, as a necessary first step, any face processing systems, such as automatic face recognition, ...

CD8+ Cytotoxic T Lymphocyte Activation by Soluble Major Histocompatibility Complex-Peptide Dimers

Horst Vogel, Jean-Manuel Segura, Olivier Michielin, Bruno Meyer

CD8+ cytotoxic T lymphocyte (CTL) can recognize and kill target cells that express only a few cognate major histocompatibility complex class I-peptide (pMHC) complexes. To better understand the mol. basis of this sensitive recognition process, the authors ...

Fusion of Structural and Color Local Descriptors for Enhanced Object Recognition

Jean-Marc Odobez, Pedro Manuel Da Silva Quelhas

In this paper we study the behavior of local descriptor object recognition methods with respect to 3D geometric transformations and image resolution variations. As expected performance decreases with accentuated perspective and decrease in resolution. To i ...

Prior exposure to a single stress session facilitates subsequent contextual fear conditioning in rats. Evidence for a role of corticosterone

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

Previous studies showed that exposure of rats to chronic restraint stress for 21 days enhances subsequent contextual fear conditioning. Since recent evidence suggest that this effect is not dependent on stress-induced neurodegenerative processes, but to el ...

What and where in human audition: selective deficits following focal hemispheric lesions

Jean-Philippe Thiran, Olivier Cuisenaire

A sound that we hear in a natural setting allows us to identify the sound source and localize it in space. The two aspects can be disrupted independently as shown in a study of 15 patients with focal right-hemispheric lesions. Four patients were normal in ...
