    Identification of versions of the same musical composition by processing audio descriptions 

    Serrà Julià, Joan (Date of defense: 2011-02-23)

    This work focuses on the automatic identification of musical piece versions (alternate renditions of the same musical composition like cover songs, live recordings, remixes, etc.). In particular, we propose two core ...

    Image analysis and deep learning to support endovascular repair of abdominal aortic aneurysms 

    López-Linares, Karen (Date of defense: 2019-06-11)

    An abdominal aortic aneurysm (AAA) is a focal dilation of the aorta that may lead to its rupture. The most common treatment for AAAs is endovascular aneurysm repair (EVAR). EVAR implies lifelong postoperative surveillance ...

    Image based analysis and modeling of the detailed cardiac ventricular anatomy 

    Paun, Bruno (Date of defense: 2017-07-24)

    The role of trabeculations and their normal morphological expression in the human heart is still unclear. Clinical studies have shown that excessive trabeculation can cause heart failure due to diastolic and systolic ...

    Image processing algorithms as artistic tools in digital cinema 

    Zabaleta Razquin, Itziar (Date of defense: 2021-10-01)

    The industry of cinema has experienced a radical change in the last decades: the transition from film cinematography to its digital format. As a consequence, several challenges have appeared, but, at the same time, many ...

    Image similarity for registration and manifold learning: application to brain analysis 

    Zimmer, Veronika Anne (Date of defense: 2017-02-13)

    The aim of this thesis is to explore and develop measures for image comparison in two main areas of medical image analysis: image registration and manifold learning for population analysis. In particular, the main contributions ...
