  • 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 ...
  • Oliver, Maria; Haro Ortega, Gloria; Dimiccoli, Mariella; Mazin, Baptiste; Ballester, Coloma (Springer, 2016)
    This paper presents a computational model to recover the most likely interpretation of the 3D scene structure from a planar image, where some objects may occlude others. The estimated scene interpretation is obtained by ...
  • 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 ...
  • Scarlett, Jonathan; Somekh-Baruch, Anelia; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper studies the mismatched decoding problem for binary-input discrete memoryless channels. An example is provided for which an achievable rate based on superposition coding exceeds the Csiszár-Körner-Hui rate, thus ...
  • Ghimpeteanu, 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 ...
  • Tauste Campo, Adrià; Vazquez-Vilar, Gonzalo; Guillén i Fàbregas, Albert; Koch, Tobias; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper studies the random-coding exponent of joint source-channel coding for a scheme where source messages are assigned to disjoint subsets (referred to as classes), and codewords are independently generated according ...
  • Ramírez, Rafael,1966-; Hazan, Amaury; Maestre Gómez, Esteban; Serra, Xavier (MIT Press, 2008)
    We describe an evolutionary approach to inducing a generative model of expressive music performance for Jazz saxophone. We begin with a collection of audio recordings of real Jazz saxophone performances from which we extract ...
  • 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 ...
  • Borda Fortuny, Cristina; Tong, Kin-Fai; Al-Armaghany, Allann; Wong, Kai-Kit (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    A fluid switch is proposed for a frequency-agile Vivaldi antenna whose operating frequency band can be switched between two selected bands. A study of various ionized solutions of different concentrations is performed. A ...
  • Pascau, J.; Vaquero, Juan J.; Chamorro-Servent, Judit; Rodríguez-Ruano, A.; Desco, Manuel (Institute of Physics (IOP), 2012)
    Small-animal positron-emission tomography/computed tomography (PET/ CT) scanners provide anatomical and molecular imaging, which enables the joint visualization and analysis of both types of data. A proper alignment calibration ...
  • 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, 1970-; 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 ...
