Individual traits versus invariances of cognitive functions: a model-based study of brain connectivity
Es conocido en la literatura de neuroimagen que las redes cerebrales funcionales reflejan rasgos personales. Estas características individuales, podrían interferir al caracterizar la cognición entendida como la manera en ...
Automatic reconstruction of complex dynamical networks
Un problema principal de la ciència de xarxes és com reconstruir (inferir) la topologia d’una xarxa real a partir de senyals mesurades de les seves unitats internes. Entendre la arquitectura d’una xarxa complexa és clau, ...
3D subject-specific shape and density modeling of the lumbar spine from 2D DXA images for osteoporosis assessment
Osteoporosis is the most common bone disease, with a significant morbidity and mortality caused by the increase of bone fragility and susceptibility to fracture. Dual Energy X-ray Absorptiometry (DXA) is the gold standard ...
Detection of directional interactions between neurons from spike trains
An important problem in neuroscience is the assessment of the connectivity between neurons from their spike trains. One recent approach developed for the detection of directional couplings between dynamics based on ...
Incorporating prosody into neural speech processing pipelines: applications on automatic speech transcription and spoken language machine translation
In this dissertation, I study the inclusion of prosody into two applications that involve speech understanding:~automatic speech transcription and spoken language translation. In the former case, I propose a method that ...
Performance evaluation of safety critical ITS-G5 V2V communications for cooperative driving Applications
Intelligent Transport Systems (ITS) are aiming to provide innovative services related to different modes of transport and traffic management, and enable various users to be better informed and make safer, more coordinated ...
Co-design strategies with children in full-body interaction for situated non-formal learning experiences
This dissertation focuses on better achieving co-design of Full-Body interactive learning experiences with children and experts (teachers, museum curators, pedagogues, etc.). Hence, on the one hand, it has studies how to ...
Spectrum analysis methods for 3D facial expression recognition and head pose estimation
Al llarg de les últimes dècades, l'anàlisi facial ha atret un interès creixent i considerable per part de la comunitat investigadora amb l’objectiu de millorar la interacció i la cooperació entre les persones i les màquines. ...
Automatic assessment of singing voice pronunciation: a case study with Jingju music
Online learning has altered music education remarkable in the last decade. Large and increasing amount of music performing learners participate in online music learning courses due to the easy-accessibility and boundless ...
Digital camera colour processing pipeline for high dynamic range imaging and colour stabilisation for cinema
In this thesis we focus on two different image processing challenges: high dynamic range (HDR) image/video generation, and colour matching. In both cases, we redefine these tasks by taking into account the prior knowledge ...
RFID autonomous robot for product inventory and location
A solution for the automation of inventory taking and location of prod-ucts in a store or warehouse is presented. Radio Frequency Identifica-tion (RFID), an automatic identification technology, and mobile robotics are ...
Left atrial parameterisation and multi-modal data analysis: application to atrial fibrillation
Many aspects related to the pathogenesis and progression of atrial fibrillation (AF) are still not fully understood. In this thesis we have contributed with (1) an automatic framework to segment the left atrium (LA) from ...
Patterns of spike synchrony in neural field models
Els models neuronals de camp mig són descripcions fenomenològiques de l'activitat de xarxes de neurones espacialment organitzades. Gràcies a la seva simplicitat, aquests models són unes eines extremadament útils per a ...
Scene understanding from image and video : segmentation, depth configuration
In this thesis we aim at analyzing images and videos at the object level, with the goal of decomposing the scene into complete objects that move and interact among themselves. The thesis is divided in three parts. First, ...
Modeling users preferences in online social networks
L'objectiu d'aquesta tesi és desenvolupar nous i diversos mètodes per modelar les preferències dels usuaris a les Xarxes Socials Online. Els mètodes proposats tenen com a finalitat ser aplicats en àrees de recerca com la ...
Temporal analysis of large dynamic graphs
The objective of this thesis is to provide a temporal analysis of the structural and interaction dynamics of large evolving graphs. In this thesis we propose new definitions of important graph metrics in order to include ...
Program synthesis for generalized planning
Generalized planning is the problem of finding an algorithm-like solution called generalized plan to multiple planning instances. The two main tasks to perform in generalized planning are synthesizing and validating ...
Multi-feature machine learning analysis for an improved characterization of the cardiac mechanics
This thesis focuses on the development of machine learning tools to better characterize the cardiac anatomy and function in the context of heart failure, and in particular their extension to consider multiple parameters ...
Multi-atlas segmentation and analysis of the fetal brain in ventriculomegaly
Nowadays, imaging of the human brain is vastly used in clinical settings and by the neuroscientific research community. There is an ever-increasing demand for novel biomedical image analysis approaches and tools to study ...
The Dynamics of hippocampal encoding: beyond the spatial metaphor
Every animal on our planet wanders around when looking for something. Whether it is in search of food, a mate, or home, navigation is one of the most performed cognitive behaviors in Nature. Nevertheless, our understanding ...
