  • Bellur, Ashwin; Ishwar, Vignesh; Serra, Xavier; Murthy, Hema A. (Universitat Pompeu Fabra, 2012)
    In this paper, we describe several techniques for detecting tonic pitch value in Indian classical music. In Indian music, the raga is the basic melodic framework and it is built on the tonic. Tonic detection is therefore ...
  • Sordo, Mohamed; Serrà Julià, Joan; Koduri, Gopala Krishna; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper a method for extracting semantic information from online music discussion forums is proposed. The semantic relations are inferred from the co-occurrence of musical concepts in forum posts, using network ...
  • Sordo, Mohamed; Koduri, Gopala Krishna; Sentürk, Sertan; Gulati, Sankalp; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In the context of the CompMusic project we are developing methods to automatically describe/annotate audio music recordings pertaining to various music cultures. As a way to demonstrate the usefulness of the methods we ...
  • Font, Frederic; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    User generated content shared in online communities is often described using collaborative tagging systems where users assign labels to content resources. As a result, a folksonomy emerges that relates a number of tags ...
  • Sentürk, Sertan; Holzapfel, Andre; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    The main information sources to study a particular piece of music are symbolic scores and audio recordings. These are complementary representations of the piece and it is very useful to have a proper linking between the ...
  • Sarala, Padi; Ishwar, Vignesh; Bellur, Ashwin; Murthy, Hema A. (Universitat Pompeu Fabra, 2012)
    A Carnatic music concert is made up of a sequence of pieces, where each piece corresponds to a particular genre and ra¯aga (melody). Unlike a western music concert, the artist may be applauded intra-performance ...
  • Gulati, Sankalp; Salamon, Justin; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper we propose a new approach for tonic identification in Indian art music and present a proposal for a complete iterative system for the same. Our method splits the task of tonic pitch identification into two ...
  • Bogunovic, Hrvoje; Pozo Soler, José Ma. (José María); Villa-Uriol, Maria-Cruz; Majoie, Charles B. L. M.; van den Berg, Rene; Gratama van Andel, Hugo A. F.; Macho, Juan M.; Blasco, Jordi; San Román, Luis; Frangi Caregnato, Alejandro (American Association of Physicists in Medicine (AAPM), 2010)
    Purpose: To evaluate the suitability of an improved version of an automatic segmentation method based on geodesic active regions (GAR) for segmenting cerebral vasculature with aneurysms from 3D X-ray reconstruc- tion ...
  • Koduri, Gopala Krishna; Serrà Julià, Joan; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    Intonation is a fundamental music concept that has a special relevance in Indian art music. It is characteristic of the rāga and intrinsic to the musical expression of the performer. Describing intonation is of importance ...
  • Piella Fenoy, Gemma; De Craene, Mathieu; Bijnens B.H.; Tobón Gómez, Catalina, 1981-; Huguet, Marina; Avegliano, G.; Frangi Caregnato, Alejandro (Elsevier, 2010)
    Introducción y objetivos. Se ha señalado que, en la miocardiopatía hipertrófica (MCH), la desorganización de las fibras regionales da lugar a segmentos en los que la deformación es nula o está gravemente reducida, y que ...
  • Font, Frederic; Roma, Gerard; Herrera Boyer, Perfecto; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    There are many online communities with membergenerated and openly available multimedia content. Their success depends on having active contributing users and on producing useful content. With this criterion, the community ...
  • Patrizini, Fabio; Lipovetzky, Nir; Giacomo, Giuseppe de; Geffner, Hector (Association for the Advancement of Artificial Intelligence (AAAI), 2011)
    Classical planning has been notably successful in synthesizing finite plans to achieve states where propositional goals hold. In the last few years, classical planning has also been extended to incorporate temporally ...
  • Bernardini, A.; Larrabide, Ignacio; Petrini, L.; Pennati, G.; Flore, E.; Kim, Minsuok; Frangi Caregnato, Alejandro (Taylor & Francis (Routledge), 2011)
    In the last few years, there has been a growing focus on faster computational methods to support clinicians in planning stenting procedures. This study investigates the possibility of introducing computational approximations ...
  • Zhang, Chong; Villa-Uriol, Maria-Cruz; De Craene, Mathieu; Pozo Soler, José Ma. (José María); Macho, Juan M.; Frangi Caregnato, Alejandro; Universitat Pompeu Fabra (American Association of Physicists in Medicine (AAPM), 2011)
    Purpose: The objective of this study is to investigate the feasibility of detecting and quantifying 3D cerebrovascular wall motion from a single 3D rotational x-ray angiography (3DRA) acquisition within a clinically ...
  • Balocco, Simone; Basset, Olivier; Courbebaisse, Guy; Boni, Enrico; Frangi Caregnato, Alejandro; Tortoli, Piero; Cachard, Christian (Institute of Physics (IOP), 2010)
    Human arteries affected by atherosclerosis are characterized by altered wall viscoelastic properties. The possibility of noninvasively assessing arterial viscoelasticity in vivo would significantly contribute to the early ...
  • Maestre Gómez, Esteban; Pérez, Alfonso; Ramírez, Rafael (International Computer Music Association, 2010)
    This paper presents a framework in which samples of bowing gesture parameters are retrieved and concatenated from a database of violin performances by attending to an annotated input score. Resulting bowing parameter signals ...
  • Ramírez Jávega, Miquel; Geffner, Hector (Association for the Advancement of Artificial Intelligence (AAAI), 2011)
    Plan recognition is the problem of inferring the goals and plans of an agent from partial observations of her behavior. Recently, it has been shown that the problem can be formulated and solved using planners, reducing ...
  • Morales, Hernán; Kim, Minsuok; Vivas, EE; Villa-Uriol, Maria-Cruz; Larrabide, Ignacio; Sola, T; Guimaraens, Leopoldo; Frangi Caregnato, Alejandro (American Society of Neuroradiology, 2011)
    Endovascular coiling is a well-established therapy for treating intracranial aneurysms. Nonetheless, postoperative hemodynamic changes induced by this therapy remain not fully understood. The purpose of this work is to ...
  • Biglieri, Ezio; Grossi, Emanuele; Lops, Marco; Tauste Campo, Adrià (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We study the minimum mean square error (MMSE) and the multiuser efficiency η of large dynamic multiple access communication systems in which optimal multiuser detection is performed at the receiver as the number and the ...
  • Zhang, Chong; Villa-Uriol, Maria-Cruz; De Craene, Mathieu; Pozo Soler, José Ma. (José María); Frangi Caregnato, Alejandro (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    This paper presents a technique to estimate and model patient-specific pulsatility of cerebral aneurysms over one cardiac cycle, using 3D rotational X-ray angiography (3DRA) acquisitions. Aneurysm pulsation is modeled as ...
