  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    This paper aims at illustrating some applications of Finite Random Set (FRS) theory to the design and analysis of wireless communication receivers, and at pointing out similarities and differences between this scenario and ...
  • Andreu, Fuensanta; Caselles, Vicente; Díaz, Jesus Ildefonso; Mazón, Jose (Elsevier, 2002)
    We prove the existence of a finite extinction time for the solutions of the Dirichlet problem for the total variation flow. For the Neumann problem, we prove that the solutions reach the average of its initial datum in ...
  • Caselles, Vicente; Chambolle, Antonin; Novaga, Matteo (European Mathematical Society (EMS), 2010)
    We show that generically the subsets of RN with finite volume RN have a unique Cheeger set, in the sense that there always exists a nearby set which has a unique Cheeger set. We also prove that Cheeger sets are C1,1, when ...
  • Hernández Leo, Davinia; Nieves, Raul; Arroyo, Ernesto; Rosales, Andrea; Melero Gallardo, Javier; Blat, Josep (Graz University of Technology. Institut für Informationssysteme und Computer Medien (IICM), 2012)
    Carrying out collaborative learning activities (supported by technologies or not)/ntypically involves the coordination of multiple participants, in their dynamic assignment to/ngroups and roles and in the distribution of ...
  • Serra, Xavier; Bresin, Roberto; Camurri, Antonio (Taylor & Francis (Routledge), 2007)
    Based on the current context of the Sound and Music Computing (SMC) field, the state of the art in research and the open issues that have been identified and described in other articles of this journal issue, in this article ...
  • Oramas, Sergio; Ostuni, Vito Claudio; Di Noia, Tommaso; Serra, Xavier; Di Sciascio, Eugenio (ACM Association for Computer Machinery, 2017)
    The Web has moved, slowly but steadily, from a collection of documents towards a collection of structured data. Knowledge graphs have then emerged as a way of representing the knowledge encoded in such data as well as a ...
  • Serra, Xavier (International Computer Music Conference, 1994)
    Current sound hybridization techniques are ha.sed on the exciter-resonator model, where the spectral characteristics of a sound (resonator) are applied to another one (exciter). The tradi­ tional implementations use Linear ...
  • Janer Mestres, Jordi; Haro Berois, Martín; Roma Trepat, Gerard; Fujishima, Takuya; Kojima, Naoaki ([Sound and Music Computing], 2009)
    Sample-based music composition often involves the task of manually searching appropriate samples from existing audio. Audio mosaicing can be regarded as a way to automatize this process by specifying the desired audio ...
  • Serra, Xavier; Bonada, Jordi, 1973- (International Conference on Digital Audio Effects, 1998)
    The basic Spectral Modeling Synthesis (SMS) technique models sounds as the sum of sinusoids plus a residual. Though this analysis/synthesis system has proved to be successful in transforming sounds, more powerful and ...
  • Pérez-Bellido, Alexis; Soto-Faraco, Salvador, 1970-; López-Moliner, Joan (American Physical Society, 2012)
    Cross-modal enhancement can be mediated both by higher-order effects due to attention and decision making and by detection-level stimulus-driven interactions. However, the contribution of each of these sources to behavioral ...
  • Soto-Faraco, Salvador, 1970-; Papai, Marta Szabina (Nature Publishing Group, 2017)
    Cross-modal interactions can lead to enhancement of visual perception, even for visual events below awareness. However, the underlying mechanism is still unclear. Can purely bottom-up cross-modal integration break through ...
  • Ferrés, Daniel; AbuRa’ed, Ahmed; Saggion, Horacio (Sociedad Española para el Procesamiento del Lenguaje Natural (SEPLN), 2017)
    Morphological Generation is the task of producing the appropiate in- flected form of a lemma in a given textual context and according to some morphological features. This paper describes and evaluates wide-coverage ...
  • Bertalmío, Marcelo; Vazquez-Corral, Javier (Elsevier, 2018)
    Gamut mapping transforms the color gamut of an image to that of a target device. Two cases are usually considered: gamut reduction (target gamut smaller than source gamut), and gamut extension (target gamut larger than ...
  • Pacheco Estefan, Daniel; Wierenga, Sytse; Omedas, Pedro; Wilbricht , Stefan; Knoch, Habbo; Verschure, Paul F. M. J. (ACM Association for Computer Machinery, 2014)
    In this study we present a novel ICT framework for the exploration and visualization of historical information using Augmented Reality (AR) and geolocalization. The framework facilitates the geolocalization of multimedia ...
  • Oliver, Maria; Palomares, Roberto P.; Ballester, Coloma; Haro Ortega, Gloria (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    We propose a new variational method for the completion of moving shapes through binary video inpainting that works by smoothly recovering the objects into an inpainting hole. We solve it by a simple dynamic shape analysis ...
  • Baus, Cristina; Bas Villalba, Jesús Antonio; Calabria, Marco; Costa, Albert, 1970- (Frontiers, 2017)
    Here we investigated how the language in which a person addresses us, native or foreign, influences subsequent face recognition. In an old/new paradigm, we explored the behavioral and electrophysiological activity associated ...
  • Farrús, Mireia; Erro, Daniel; Hernando, Javier (Universidad de Valladolid, 2008)
    Security systems relying on voice identification can be threatened by human voice imitation or synthetic voices. As voice conversion can be seen as a sort of voice imitation, this paper analyses the performance of an ...
  • Biau, Emmanuel, 1985-; Torralba, Mireia; Fuentemilla, Lluis; De Diego Balaguer, Ruth; Soto-Faraco, Salvador, 1970- (Elsevier, 2015)
    Speakers often accompany speech with spontaneous beat gestures in natural spoken communication. These gestures are usually aligned with lexical stress and can modulate the saliency of their affiliate words. Here we addressed ...
  • 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 ...
  • Bonada, Jordi, 1973-; Loscos, Àlex; Cano, Pedro; Serra, Xavier; Kenmochi, Hideki (Audio Engineering Society, 2001)
    In this paper we present two different approaches to the modeling of the singing voice. Each of these approaches has been thought to fit in the specific requirements of two applications. These are an automatic voice impersonator ...
