  • Zamir, Syed Waqas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Emerging display technologies are able to produce images with a much wider color gamut than those of conventional distribution gamuts for cinema and TV, creating an opportunity for the development of gamut extension ...
  • Zamir, Syed Waqas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Gamut mapping transforms the colors of an input/nimage to the colors of a target device so as to exploit the full/npotential of the rendering device in terms of color rendition. In/nthis paper we present spatial gamut ...
  • Andrzejak, Ralph Gregor; Ruzzene, Giulia; Malvestio, Irene (American Institute of Physics (AIP), 2017)
    Networks of coupled oscillators in chimera states are characterized by an intriguing interplay of synchronous and asynchronous motion. While chimera states were initially discovered in mathematical model systems, there ...
  • Aragón, Pablo; Gómez, Vicenç; García, David; Kaltenbrunner, Andreas (SpringerOpen, 2017)
    Online discussion in form of written comments is a core component of many social media platforms. It has attracted increasing attention from academia, mainly because theories from social sciences can be explored at an ...
  • Ferradans Ramonde, Sira; Bertalmío, Marcelo; Caselles, Vicente (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Demosaicking is a particular case of interpolation problems where, from a scalar image in which each pixel has either the red, the green or the blue component, we want to interpolate the full-color image. State-of-the-art ...
  • Dutra, T. B.; Marques, Ricardo; Cavalcante‐Neto, J.B.; Vidal, C. A.; Pettré, J. (Wiley, 2017)
    Most recent crowd simulation algorithms equip agents with a synthetic vision component for steering. They offer promising perspectives through a more realistic simulation of the way humans navigate according to their ...
  • Bettinardi, Ruggero G.; Tort-Colet, Núria; Ruiz Mejias, Marcel; Sanchez-Vives, Maria V; Deco, Gustavo (Elsevier, 2015)
    Intrinsic brain activity is characterized by the presence of highly structured networks of correlated fluctuations between different regions of the brain. Such networks encompass different functions, whose properties are ...
  • Melero Merino, Javier; Hernández Leo, Davinia; Manatunga, Kalpani (Elsevier, 2015)
    Within the field of Game-based Learning (GBL) location-based games are based on pervasive and mobile learning to allow the creation of in situ learning activities considering gamification mechanisms. In these learning ...
  • Ikumi Montserrat, Nara, 1986-; Soto Faraco, Salvador (Frontiers, 2017)
    Perception in multi-sensory environments involves both grouping and segregation of events across sensory modalities. Temporal coincidence between events is considered a strong cue to resolve multisensory perception. However, ...
  • Serra, Xavier (Taylor & Francis (Routledge), 2003)
  • Biau, Emmanuel, 1985-; Morís Fernández, Luis, 1982-; Holle, Henning; Avila, César; Soto-Faraco, Salvador, 1970- (Elsevier, 2016)
    During public addresses, speakers accompany their discourse with spontaneous hand gestures (beats) that are tightly synchronized with the prosodic contour of the discourse. It has been proposed that speech and beat gestures ...
  • Manathunga, Kalpani; Hernández Leo, Davinia (International Forum of Educational Technology & Society, 2015)
    There is a growing interest in understanding to what extent innovative educational technologies can be used to/nsupport massive courses. Collaboration is one of the main desired elements in massive learning actions/ninvolving ...
  • Lozano Solsona, Angel; Tulino, Antonia M.; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    The analysis of the multiantenna capacity in the high-SNR regime has hitherto focused on the high-SNR slope (or maximum multiplexing gain), which quantifies the multiplicative /nincrease as function of the number of antennas. ...
  • Kaplan, Raphael; Adhikari, Mohit H.; Hindriks, Rikkert; Mantini, Dante; Murayama, Yusuke (Elsevier, 2016)
    The default mode network (DMN) is a commonly observed resting-state network (RSN) that includes medial temporal, parietal, and prefrontal regions involved in episodic memory [1-3]. The behavioral relevance of endogenous ...
  • Rolls, Edmund T; Dempere-Marco, Laura; Deco, Gustavo (Public Library of Science, 2013)
    Human short term memory has a capacity of several items maintained simultaneously. We show how the number of short term memory representations that an attractor network modeling a cortical local network can simultaneously ...
  • Martin, Clara D.; García, Xavier, 1967-; Potter, Douglas; Melinger, Alissa; Costa, Albert, 1970- (Taylor & Francis (Routledge), 2016)
    Native speakers with different linguistic backgrounds differ in their usage of language, and particularly in their vocabulary. For instance, British natives would use the word "holiday" when American natives would prefer ...
  • Deco, Gustavo; Senden, Mario; Jirsa, Viktor K. (Frontiers, 2012)
    Resting state networks (RSNs) show a surprisingly coherent and robust spatiotemporal/norganization. Previous theoretical studies demonstrated that these patterns can be/nunderstood as emergent on the basis of the underlying ...
  • Nakagawa, Tristan T.; Woolrich, Mark; Luckhoo, Henry; Joensson, Morten; Mohseni, Hamid; Kringelbach, Morten L.; Jirsa, Viktor K.; Deco, Gustavo (Elsevier, 2014)
    In recent years the study of the intrinsic brain dynamics in a relaxed awake state in the absence of any specific/ntask has gained increasing attention, as spontaneous neural activity has been found to be highly structured ...
  • Morales, Hernán G.; Kim, Minsuok; Vivas, EE; Villa-Uriol, Maria-Cruz; Larrabide, Ignacio, 1978-; 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 ...
  • Foucart, Alice; Ruiz Tada, Elisa; Costa, Albert, 1970- (Taylor & Francis (Routledge), 2015)
    Most event-related brain potential (ERP) studies that showed the role of anticipation processes during sentence processing focused on reading. However, in everyday conversation speech unfolds at higher speed; the present ...
