  • Bertalmío, Marcelo; Batard, Thomas (International Press of Boston, 2016)
    We extend two existing variational models from the Euclidean space to a vector bundle over a Riemannian manifold. The Euclidean models, dedicated to regularize or enhance some color image features, are based on the concept ...
  • Panagiotaropoulos, Theofanis I.; Kapoor, Vishal; Logothetis, N.; Deco, Gustavo (Public Library of Science, 2013)
    The neural correlates of conscious visual perception are commonly studied in paradigms of perceptual multistability that/nallow multiple perceptual interpretations during unchanged sensory stimulation. What is the source ...
  • Sfairopoulou, Anna; Bellalta, Boris; Macián, Carlos; Oliver Riera, Miquel (Springer Verlag, 2010)
    In multi-rate WLANs, users can suffer transmission rate changes due to the link adaptation mechanism. This results in a variable capacity channel, which is very hostile for VoIP and can cause serious quality of service ...
  • García Cañadilla, Patricia, 1985-; Rudenick, Paula A.; Crispi Brillas, Fàtima; Cruz-Lemini, Mónica; Palau, Georgina; Camara, Oscar; Gratacós Solsona, Eduard; Bijnens, Bart (Public Library of Science, 2014)
    Intrauterine growth restriction (IUGR) due to placental insufficiency is associated with blood flow redistribution in order to/nmaintain delivery of oxygenated blood to the brain. Given that, in the fetus the aortic isthmus ...
  • Pérez Sanagustín, Maria del Mar; Santos Rodríguez, Patrícia; Moghnie, Ayman; Hernández Leo, Davinia; Blat, Josep (Inderscience Enterprises Ltd, 2009)
    The emergence of the Web 2.0 technologies in the last years have/nchanged the way people interact with knowledge. Services for cooperation and/ncollaboration have placed the user in the centre of a new knowledge building/nspace. ...
  • Cardelino, Juan; Caselles, Vicente; Bertalmío, Marcelo; Randall, Gregory (SIAM (Society for Industrial and Applied Mathematics), 2013)
    We present a novel segmentation algorithm based on a hierarchical representation of images. The main contribution of this work is to explore the capabilities of the a contrario reasoning when applied to the segmentation ...
  • Ghimpeţeanu, Gabriela; Batard, Thomas; Bertalmío, Marcelo; Levine, Stacey (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    In this paper, we consider an image decomposition model that provides a novel framework for image denoising. The model computes the components of the image to be processed in a moving frame that encodes its local geometry ...
  • Steck, Kathrin; Veit, Daniel; Grandy, Ronald; Bermúdez i Badia, S.; Mathews, Zenon; Verschure, Paul F. M. J.; Hansson, B. S. (Bill S.), 1959-; Knaden, Markus (Nature Publishing Group, 2012)
    How can odor-guided behavior of numerous individual Drosophila be assessed automatically with high temporal resolution? For this purpose we introduce the automatic integrated tracking and odor-delivery system Flywalk. In ...
  • Costa-jussà, Marta R.; Fonollosa, José A Rodriguez; Mariño Acebal, José B.; Poch, Marc; Farrús, Mireia (Institute of Informatics Slovak Academy of Sciences, 2014)
    We present a large Spanish-Catalan parallel corpus extracted from ten years of the paper edition of a bilingual Catalan newspaper. The produced corpus of 7:5M parallel sentences (around 180M words per language) is useful ...
  • Gómez, Vicenç; Kappen, Hilbert J.; Litvak, Nelly; Kaltenbrunner, Andreas (Springer, 2013)
    Online discussion threads are conversational cascades in the form of posted messages that can be generally found in social systems that comprise many-to-many interaction such as blogs, news aggregators or bulletin board ...
  • Melero Gallardo, Javier; Hernández Leo, Davinia (International Forum of Educational Technology & Society, 2014)
    Multiple evidences in the Technology-Enhanced Learning domain indicate that Game-Based Learning can lead to positive effects in students’ performance and motivation. Educational games can be completely virtual or can combine ...
  • Hernández Leo, Davinia; Jorrín-Abellán, Iván M.; Villasclaras-Fernández, Eloy D.; Asensio-Pérez, Juan I.; Dimitriadis, Yannis (Elsevier, 2010)
    Collage is a pattern-based visual design authoring tool for the creation of collaborative learning scripts computationally modelled with IMS Learning Design (LD). The pattern-based visual approach aims to provide teachers ...
  • Albantakis, Larissa; Branzi, Francesca Martina, 1984-; Costa, Albert; Deco, Gustavo (Public Library of Science, 2012)
    The role of changes of mind and multiple choices has recently received increased attention in the study of perceptual/ndecision-making. Previously, these extensions to standard two-alternative tasks have been studied ...
  • Penacchio, Olivier; Otazu, Xavier; Dempere-Marco, Laura (Public Library of Science, 2013)
    Brightness induction is the modulation of the perceived intensity of an area by the luminance of surrounding areas. Recent/nneurophysiological evidence suggests that brightness information might be explicitly represented ...
  • Cyriac, Praveen; Batard, Thomas; Bertalmío, Marcelo (SIAM (Society for Industrial and Applied Mathematics), 2014)
    Due to technical limitations, common display devices can only reproduce images having a low range of intensity values (dynamic range). As a consequence, the dynamic range of images encoding real world scenes, which is ...
  • Melero Gallardo, Javier; Hernández Leo, Davinia; Blat, Josep (Graz University of Technology. Institut für Informationssysteme und Computer Medien (IICM), 2012)
    Information and Communication Technology (ICT) engineering education is facing/na decreasing interest by students. To deal with this issue, a need for shifting from traditional/nlearning approaches to constructivist methods ...
  • Rennó Costa, César; Lisman, John E.; Verschure, Paul F. M. J. (Public Library of Science, 2014)
    The notion of attractor networks is the leading hypothesis for how associative memories are stored and recalled. A defining/nanatomical feature of such networks is excitatory recurrent connections. These ‘‘attract’’ the ...
  • Jindal, Nihar; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The optimization of the pilot overhead in single-user wireless fading channels is investigated, and the dependence of this overhead on various system parameters of interest (e.g., fading rate, signal-to-noise ratio) is ...
