Prados Gutiérrez, Ricard (Date of defense: 2013-05-02)
The fusion of several images of the same scene into a single and larger composite is known as photo-mosaic. Unfortunately, the seams along image boundaries are often noticeable, due to photometrical and geometrical ...
Caro Perez, Luis Fernando (Date of defense: 2010-01-19)
Ethernet está empezando a pasar de las redes de área local a una red de transporte. Sin embargo, como los requisitos de las redes de transporte son más exigentes, la tecnología necesita ser mejorada. Esquemas diseñados ...
Solano Donado, Fernando (Date of defense: 2007-12-04)
All-Optical Label Swapping (AOLS) es una tecnología clave para la implementación de nodos de conmutación completamente óptica de paquetes. Sin embargo, el costo de su desarrollo es proporcional al tamaño del espacio de ...
Batlle Subirós, Elisabet (Date of defense: 2008-12-19)
The first part of this work presents an accurate analysis of the most relevant 3D registration techniques, including initial pose estimation, pairwise registration and multiview registration strategies. A new classification ...
Gómez Ardila, Sergio Eduardo (Date of defense: 2013-06-06)
Mobile learning (m-learning) is still in its infancy, and great efforts should be made so as to investigate the potentials of an educational paradigm shift from the traditional one-size-fits-all teaching approaches to an ...
Zappella, Luca (Date of defense: 2011-06-30)
En aquesta tesi s’estudia el problema de la segmentació del moviment. La tesi presenta una revisió dels principals algoritmes de segmentació del moviment, s’analitzen les característiques principals i es proposa una ...
Bolívar Díaz, Nicolás (Date of defense: 2012-07-30)
Cognitive Radio (CR) is one possible option for mitigating the inefficient wireless spectrum distribution that occurs as a result of fixed spectrum allocation. The use of Dynamic Spectrum Access capabilities will potentially ...
Mahmood, Muhammad Habib (Date of defense: 2018-11-16)
Motion segmentation refers to the process of separating regions and trajectories from a video sequence into coherent subsets of space and time. In this thesis, we created a new multifaceted motion segmentation dataset ...
Puiggalí, Joan (Date of defense: 2012-11-07)
The research we have conducted has been aimed at developing a new mechanism of extraction and use of parallelism at a high level, based on speculation techniques, in cluster environments. This allows our mechanism to be ...
Manzano Castro, Marc (Date of defense: 2014-11-20)
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 ...
Fernández Navarro, Sergio (Date of defense: 2012-06-22)
This thesis focuses on the problem of 3D acquisition using coded structured light (CSL). In CSL, a projected pattern impinges artificial texture onto the object surface, increasing the number of correspondences in the ...
Vidal Garcia, Eduard (Date of defense: 2019-11-28)
Autonomous underwater vehicles are used nowadays in many applications. One of the applications is mapping of a particular area of the ocean. Quen the robot needs to cover the area of interest and no prior knowledge of ...
Vallicrosa Massaguer, Guillem (Date of defense: 2018-11-15)
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 ...
Hernández Vega, Juan David (Date of defense: 2017-10-26)
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 ...
Hernàndez Bes, Emili (Date of defense: 2012-06-15)
This thesis addresses the path planning problem for Autonomous Underwater Vehicles (AUVs) using homotopy classes to provide topological information on how paths avoid obstacles. Looking for a path within a homotopy class ...
Carrera Viñas, Arnau (Date of defense: 2017-07-21)
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 ...
Ghose, Soumya (Date of defense: 2012-10-19)
Prostate segmentation in trans rectal ultrasound (TRUS) and magnetic resonance images (MRI) facilitates volume estimation, multi-modal image registration, surgical planing and image guided prostate biopsies. The objective ...
Segovia Silvero, Juan (Date of defense: 2011-12-15)
This thesis studies robustness against large-scale failures in communications networks. If failures are isolated, they usually go unnoticed by users thanks to recovery mechanisms. However, such mechanisms are not effective ...
Torrent Palomeras, Albert (Date of defense: 2013-07-08)
This thesis deals with the simultaneous detection and segmentation for generic objects in images. The proposed approach is based on building a dictionary of patches, which defines the object and allows the extraction of ...
Lee, Chee Sing (Date of defense: 2015-09-01)
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 ...
