Abstract:
Les technologies du numérique ont joué un rôle déterminant dans la transformation de notre société. Des méthodes statistiques récentes ont été déployées avec succès afin d’automatiser le traitement de la quantité croissante d’images, de vidéos et de textes que nous produisons quotidiennement. En particulier, les réseaux de neurones profonds ont été adopté par les communautés de la vision par ordinateur et du traitement du langage naturel pour leur capacité à interpréter le contenu des images et des textes une fois entraînés sur de grands ensembles de données.

Abstract:
Corticomuscular coupling analysis using multiple data sets such as electroencepha-logram (EEG) and electromyogram (EMG) signals provides a useful tool for understanding human motor control systems. A popular conventional method to assess corticomuscular coupling is the pair-wise magnitude-squared coherence (MSC). However, there are certain limitations associated with MSC, including the difficulty in robustly assessing group inference, only dealing with two types of data sets simultaneously and the biologically implausible assumption of pair-wise interactions.

This thesis addresses the use of multimodal signal processing to develop algorithms for the automated processing of two cardiorespiratory disorders. The aim of the first application of this thesis was to reduce false alarm rate in an intensive care unit. The goal was to detect five critical arrhythmias using processing of multimodal signals including photoplethysmography, arterial blood pressure, Lead II and augmented right arm electrocardiogram (ECG). A hierarchical approach was used to process the signals as well as a custom signal processing technique for each arrhythmia type. Sleep disorde

For several decades, pediatricians used to believe that neonates do not feel pain. The American Academy of Pediatrics (AAP) recognized neonates' sense of pain in 1987. Since then, there have been many studies reporting a strong association between repeated pain exposure (under-treatment) and alterations in brain structure and function. This association has led to the increased use of anesthetic medications. However, recent studies found that the excessive use of analgesic medications (over-treatment) can cause many side effects.

Abstract:
Les centres d’appels d’urgence jouent un rôle essentiel dans la gestion des situations de crise, car ils sont les intervenants de première ligne qui facilitent l’intervention, déterminant souvent la différence entre la vie et la mort. Les progrès récents et rapides de l’intelligence artificielle (IA) ne peuvent être négligés, car ils ont ouvert de nouveaux horizons pour améliorer les capacités des services d’urgence. Avec des applications d’IA adéquates, il est possible d’aider les centres d’appels d’urgence à améliorer l’efficacité et la précision de la gestion des urgences, sauvant ainsi pot

Abstract:
This thesis investigates the employment of different deformable registration techniques to register pre-operative magnetic resonance and inter-operative ultrasound images during prostate biopsy. Accurate registration ensures appropriate biopsy sampling of malignant prostate tissues and reduces the rate of re-biopsies. Therefore, we provide comparisons and experimental results for some landmark- and intensity-based registration methods: thin-plate splines, free-form deformation with B-splines. The primary contribution of this thesis is a new spline-based diffeomorphic registration framework for

Abstract:
L'adoption des dossiers médicaux électroniques dans les systèmes d'information des hôpitaux a conduit à la définition de bases de données regroupant divers types de données telles que des notes cliniques textuelles, des événements médicaux longitudinaux et des informations statiques sur les patients. Toutefois, les données ne sont renseignées que lors des consultations médicales ou des séjours hospitaliers. La fréquence de ces visites varie selon l’état de santé du patient. Ainsi, un système capable d'exploiter les différents types de données collectées à différentes échelles de temps est esse

Abstract:
Texts and images provide alternative, yet orthogonal views of the same underlying cognitive concept. By uncovering synergistic, semantic relationships that exist between words and images, I am working to develop novel techniques that can help improve tasks in natural language processing, as well as effective models for text-to-image synthesis, image retrieval, and automatic image annotation. Specifically, in my dissertation, I will explore the interoperability of features between language and vision tasks. In the first part, I will show how it is possible to apply features generated using evid
