  • Pons, Jordi; Janer Mestres, Jordi; Rode, Thilo; Nogueira, Waldo (Acoustical Society of America, 2016)
    Music perception remains rather poor for many Cochlear Implant (CI) users due to the users' deficient pitch perception. However, comprehensible vocals and simple music structures are well perceived by many CI users. In ...
  • Umbert Morist, Martí; Bonada, Jordi, 1973-; Goto, Masataka; Nakano, Tomoyasu; Sundberg, Johan (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    In the context of singing voice synthesis, expression control manipulates a set of voice features related to a particular emotion, style, or singer. Also known as performance modeling, it has been approached from different ...
  • Martínez García, Marina; Cyriac, Praveen; Batard, Thomas; Bertalmío, Marcelo; Malo, Jesús (Public Library of Science (PLoS), 2018)
    In vision science, cascades of Linear+Nonlinear transforms are very successful in modeling a number of perceptual experiences. However, the conventional literature is usually too focused on only describing the forward ...
  • Batard, Thomas; Bertalmío, Marcelo (Springer, 2018)
    Human perception involves many features like contours, shapes, textures, and colors to name a few. Whereas several geometric models for contours, shapes and textures perception have been proposed, the geometry of color ...
  • Grimaldi, Antoine Vincent; Kane, David; Bertalmío, Marcelo (Association for Research in Vision and Ophthalmology (ARVO), 2019)
    The statistics of real world images have been extensively investigated, but in virtually all cases using only low dynamic range image databases. The few studies that have considered high dynamic range (HDR) images ...
  • Martínez García, Marina; Bertalmío, Marcelo; Malo, Jesús (Frontiers, 2019)
    Subjective image quality databases are a major source of raw data on how the visual system works in naturalistic environments. These databases describe the sensitivity of many observers to a wide range of distortions of ...
  • Torrents-Barrena, Jordina; Piella Fenoy, Gemma; Masoller, Narcís; Gratacós Solsona, Eduard; Eixarch, Elisenda; Ceresa, Mario; González Ballester, Miguel Ángel, 1973- (Elsevier, 2019)
    Recent advances in fetal magnetic resonance imaging (MRI) open the door to improved detection and characterization of fetal and placental abnormalities. Since interpreting MRI data can be complex and ambiguous, there is a ...
  • Nurchis, Maddalena; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    The increasing interest in ubiquitous networking, and the tremendous popularity gained by IEEE 802.11 WLANs in recent years, is leading to very dense deployments where high levels of channel contention may prevent meeting ...
  • Serrà, Joan; Corral, Álvaro; Boguñá, Marián; Haro Berois, Martín; Arcos, Josep Lluis (Nature Research, 2012)
    Popular music is a key cultural expression that has captured listeners' attention for ages. Many of the structural regularities underlying musical discourse are yet to be discovered and, accordingly, their historical ...
  • Papiotis, Panagiotis, 1985-; Marchini, Marco, 1984-; Pérez Carrillo, Alfonso Antonio, 1977-; Maestre Gómez, Esteban (Frontiers, 2014)
    In a musical ensemble such as a string quartet, the musicians interact and influence each other's actions in several aspects of the performance simultaneously in order to achieve a common aesthetic goal. In this article, ...
  • Maestre Gómez, Esteban; Papiotis, Panagiotis, 1985-; Marchini, Marco, 1984-; Llimona, Joaquim; Mayor Soto, Oscar; Pérez Carrillo, Alfonso Antonio, 1977-; Wanderley, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    The authors provide a first-person outlook on the technical challenges involved in the recording, analysis, archiving, and cloud-based interchange of multimodal string quartet performance data as part of a collaborative ...
  • Wilhelmi Roca, Francesc; Cano, Cristina; Neu, Gergely; Bellalta, Boris; Jonsson, Anders, 1973-; Barrachina Muñoz, Sergio (Elsevier, 2019)
    Next-generation wireless deployments are characterized by being dense and uncoordinated, which often leads to inefficient use of resources and poor performance. To solve this, we envision the utilization of completely ...
  • Barrachina Muñoz, Sergio; Wilhelmi Roca, Francesc; Bellalta, Boris (Elsevier, 2019)
    Wireless local area networks (WLANs) are the most popular kind of wireless Internet connection because of their simplicity of deployment and operation. As a result, the number of devices accessing the Internet through WLANs ...
  • Rankothge, Windhya; Le, Franck; Russo, Alessandra; Lobo, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    With the introduction of network function virtualization technology, migrating entire enterprise data centers into the cloud has become a possibility. However, for a cloud service provider (CSP) to offer such services, ...
  • Ramírez, Rafael; Giraldo, Sergio (Taylor & Francis, 2016)
    We present a machine learning approach to automatically generate expressive (ornamented) jazz performances from un-expressive music scores. Features extracted from the scores and the corresponding audio recordings performed ...
  • Marques, Ricardo; Bouville, Christian; Bouatouch, Kadi (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    We propose a theoretical framework, based on the theory of Sobolev spaces, that allows for a comprehensive analysis of quadrature rules for integration over the sphere. We apply this framework to the case of shading ...
  • Monte Ordoño, Julia, 1989-; Toro Soto, Juan Manuel, 1976- (Elsevier, 2017)
    The Consonant-Vowel hypothesis suggests that consonants and vowels tend to be used differently during language processing. In this study we explored whether these functional differences trigger different neural responses ...
  • Crespo Bojorque, Paola, 1985-; Toro Soto, Juan Manuel, 1976- (American Physiological Society, 2016)
    Consonance is a salient perceptual feature in harmonic music associated with pleasantness. Besides being deeply rooted in how we experience music, research suggests consonant intervals are more easily processed than dissonant ...
  • Toro Soto, Juan Manuel, 1976-; Nespor, Marina; Gervain, Judit (Elsevier, 2016)
    A recurrent question regarding language acquisition is the extent to which the mechanisms human infants use to discover patterns over the linguistic signal are highly specialized and uniquely human, or are the result of ...
  • Attarifar, Masoud; Abbasfar, Aliazam; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    We present a modification of conjugate beamforming for the forward link of cell-free massive MIMO networks. This modification eliminates the self-interference and yields a performance that, without forward pilots, closely ...
