Shihavuddin, A.S.M. (Date of defense: 2014-03-28)
This thesis addresses the problem of automated underwater optical image characterization. Remote underwater optical sensing allows the collection and storage of vast amounts of data for which manual classification may take ...
Pons Rodríguez, Gerard (Date of defense: 2014-01-21)
This thesis deals with the detection, segmentation and classification of lesions on sonography. The contribution of the thesis is the development of a new Computer-Aided Diagnosis (CAD) framework capable of detecting, ...
Massich i Vall, Joan (Date of defense: 2013-12-04)
This thesis analyses the current strategies to segment breast lesions in Ultra-Sound (US) data and proposes a fully automatic methodology for generating accurate segmentations of breast lesions in US data with low false ...
Mejía Corredor, Carolina (Date of defense: 2013-10-14)
During the past years, the adoption of Learning Management System (LMS) to support an e-learning process has been continuously growing. Hence, a potential need and meaningful factor to provide a personalized support, within ...
Cabezas Grebol, Mariano (Date of defense: 2013-07-16)
This thesis deals with the segmentation of brain magnetic resonance imaging applied to multiple sclerosis patients. This disease is characterised by the presence of white matter lesions in this image modality. After a ...
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 ...
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 ...
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 ...
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 ...
Baldiris Navarro, Silvia Margarita (Date of defense: 2012-12-14)
This thesis aim for promoting the learning objects economy by offering teacher the possibility of generating adaptive and standardized learning designs. The adaptation of the generated learning design considers two of the ...
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 ...
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 ...
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 ...
Bacca Cortés, Eval Bladimir (Date of defense: 2012-06-20)
This work proposes an appearance-based SLAM method whose main contribution is the Feature Stability Histogram (FSH). The FSH is built using a voting schema, if the feature is re-observed, it will be promoted; otherwise it ...
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 ...
Quintana Plana, Josep (Date of defense: 2012-06-14)
This thesis investigates the problem of developing new computer vision techniques for early detection of skin cancer. The first part of this work presents a novel methodology to correct color reproduction in dermatological ...
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 ...
Palomeras Rovira, Narcís (Date of defense: 2011-12-19)
The presented work focuses on the theoretical and practical aspects concerning the design and development of a formal method to build a mission control system for autonomous underwater vehicles bringing systematic design ...
Elibol, Armagan (Date of defense: 2011-07-29)
Large scale image mosaicing methods are in great demand among scientists who study different aspects of the seabed, and have been fostered by impressive advances in the capabilities of underwater robots in gathering optical ...
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 ...
