3D underwater SLAM using sonar and laser sensors
This thesis presents a SLAM algorithm using a multibeam echosounder, a new 1/2 underwater laser scanner for online 3D perception and two applications of this new laser scanner: inspection and intervention. The SLAM ...
Online acoustic localization methods for autonomous underwater vehicles
Autonomous Underwater Vehicles (AUVs) true autonomy capabilities in complex unknown environments, have not yet been fully achieved because of the lack of online algorithms that can solve fundamental problems such as ...
Underwater navigation and mapping with an omnidirecional optical sensor
Omnidirectional vision has received increasing interest during the last decade from the computer vision community. However, the use of omnidirectional cameras underwater is still very limited. In this thesis we propose ...
Tracing the creation and evaluation of accessible Open Educational Resources through learning analytics
The adoption of Open Educational Resources (OER) has been continuously growing and with it the need to addressing the diversity of students’ learning needs. Because of that, OER should meet with characteristics such as the ...
Case-level detection of mammographic masses
This thesis is focused on the automatic detection of masses in FFDM images by using case-level information which includes bilateral, temporal and/or ipsilateral information. As a first step, FFDM images are preprocessed ...
Glandular tissue pattern analysis through multimodal MRI-mammography registration
Breast cancer is the most common cancer among women worldwide. Several studies have shown that the combination of the different medical image modalities, such as the x-ray mammography and the magnetic resonance imaging ...
Online path planning for autonomous underwater vehicles under motion constraints
The most common applications of autonomous underwater vehicles (AUVs) include imaging and inspecting different kinds of structures on the sea. Most of these applications require a priori information of the area or structure ...
Clinical decision support for screening, diagnosis and assessment of respiratory diseases: chronic obstructive pulmonary disease as a use case
In this thesis we propose a framework for designing, developing, a clinical decision support systems (CDSS) offering a suite of services for the early detection and assessment of chronic obstructive pulmonary disease (COPD), ...
Robot learning applied to autonomous underwater vehicles for intervention tasks
The interest in performing underwater tasks using Autonomous Underwater Vehicles (AUVs) has been growing over the past few years. In this thesis, a flexible framework for underwater interventions using a Learning ...
Supporting technology for augmented reality game-based learning
In this thesis, Augmented Reality Game-Based Learning (ARGBL) is explored and arguments are given in favor of its application in the classrooms. The thesis explores the concept and proposes technologies, theories and ...
Framework for the design and development of motivational augmented reality learning experiences in vocational education and training
One of the advantages of Augmented Reality (AR) in education is that AR increases student motivation. However, there is a lack of research on guidelines to inform the design and development of motivational AR learning ...
Tools for 3D point cloud registration
In this thesis, we did an in-depth review of the state of the art of 3D registration, evaluating the most popular methods. Given the lack of standardization in the literature, we also proposed a nomenclature and a ...
Automated methods on magnetic resonance brain imaging in multiple sclerosis
In this thesis, we have focused on the image pre-processing in order to enhance the image information. The main aspects of this enhancement rely on removing any image noise and correcting any intensity bias induced by the ...
An approach to melanoma classification exploiting polarization information
Malignant melanoma is the deadliest of skin cancers and causes the majority of deaths in comparison to other skin-related malignancies. Yet it is the most treatable type of cancer, thanks to its early diagnosis. Subsequently, ...
Simultaneous localization and mapping using single cluster probability hypothesis density filters
The majority of research in feature-based SLAM builds on the legacy of foundational work using the EKF, a single-object estimation technique. Because feature-based SLAM is an inherently multi-object problem, this has led ...
Web-based application for medical imaging management
Prostate and breast cancer are the most common cause of cancers in men and women, respectively. Medical imaging plays an important role in breast and prostate cancer detection and evaluation. Then to prove that our web-based ...
New robustness evaluation mechanism for complex networks
Network science has significantly advanced in the last decade, providing insights into the underlying structure and dynamics of complex networks. Critical infrastructures such as telecommunication networks play a pivotal ...
Forward-looking sonar mosaicing for underwater environments
Vehicle operations in underwater environments are frequently compromised by poor visibility conditions. In this thesis, we propose an end-to-end mosaicing framework tailored to the characteristics of forward-looking sonar ...
A geometric routing scheme in word-metric spaces for data networks
This research work explores the use of the Greedy Geometric Routing (GGR) schemes to solve the scalability problem of the routing systems in Internet-like networks and several families of Data Center architectures. We ...
Automated detection of new multiple sclerosis lesions in longitudinal brain magnetic resonance imaging
This thesis deals with the detection of new multiple sclerosis (MS) lesions in longitudinal brain magnetic resonance (MR) imaging. This disease is characterized by the presence of lesions in the brain, predominantly in the ...
