  • Vazquez-Corral, Javier; Bertalmío, Marcelo (MDPI, 2014)
    It has now been 20 years since the seminal work by Finlayson et al. on the use/nof spectral sharpening of sensors to achieve diagonal color constancy. Spectral sharpening is/nstill used today by numerous researchers for ...
  • Marques, Ricardo; Bouville, Christian; Ribardière, Mickaël; Santos, Luís Paulo (Wiley, 2013)
    Quasi-Monte Carlo (QMC) methods exhibit a faster convergence rate than that of classic Monte Carlo methods. This feature has made QMC prevalent in image synthesis, where it is frequently used for approximating the value of ...
  • Correia, Teresa; Aguirre, Juan; Sisniega, Alejandro; Chamorro Servent, Judit; Abascal, Juan F.P.J.; Vaquero, Juan J.; Desco, Manuel; Arridge, Simon (Optical Society of America (OSA), 2011)
    Fluorescence diffuse optical tomography (fDOT) is an imaging modality that provides images of the fluorochrome distribution within the object of study. The image reconstruction problem is ill-posed and highly underdetermined ...
  • Ventura Campos, Noelia; Sanjuán, Ana; González, Julio; Palomar García, María Ángeles; Rodríguez Pujadas, Aina; Sebastián Gallés, Núria; Deco, Gustavo; Ávila, César (Society for Neuroscience, 2013)
    Can learning capacity of the human brain be predicted from initial spontaneous functional connectivity (FC) between brain areas involved in a task? We combined task-related functional magnetic resonance imaging (fMRI) and ...
  • Tobón Gómez, Catalina, 1981-; Zuluaga, Maria A.; Chubb, Henry; Williams, Steven E.; Butakoff, Constantine; Karim, Rashed; Camara, Oscar; Ourselin, Sebastien; Rhode, Kawal (BioMed Central, 2015)
    Atrial fibrillation (AF) can be treated by catheter abla-/ntion to electrically isolate t/nhe pulmonary veins (PVs)/nfrom the left atrial (LA) body. To guide the procedure,/nan anatomical representation of the LA is usually ...
  • Parés, Narcís, 1966-; Carreras, Anna; Durany, Jaume; Ferrer, Jaume; Freixa Font, Pere; Gómez, David; Kruglanski, O.; Parés, Roc, 1968-; Ribas, Joan Ignasi; Soler, M.; Sanjurjo, A. (Mary Ann Liebert, Inc, 2006)
    On starting to think about interaction design for low-functioning persons in the autistic spectrum (PAS), especially children, one finds a number of questions that are difficult to answer: Can we typify the PAS user? Can ...
  • Serrà Julià, Joan; Gómez Gutiérrez, Emilia, 1975-; Herrera Boyer, Perfecto; Serra, Xavier (Taylor & Francis (Routledge), 2008)
    Motivated by evidence that image source statistics predict the response properties of several visual perception aspects, we provide an empirical analysis of the relation between chroma statistics and human judgments of ...
  • Costa-jussà, Marta R.; Farrús, Mireia (ACM Association for Computer Machinery, 2014)
    Machine translation can be considered a highly interdisciplinary and multidisciplinary field because it is approached from the point of view of human translators, engineers, computer scientists, mathematicians and linguists. ...
  • Maestre Gómez, Esteban; Blaauw, Merlijn; Bonada, Jordi, 1973-; Guaus, Enric; Pérez Carrillo, Alfonso Antonio, 1977- (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Excitation-continuous music instrument control patterns are often not explicitly represented in current sound synthesis techniques when applied to automatic performance. Both physical model-based and sample-based synthesis ...
  • Rolls, Edmund T; Deco, Gustavo (Elsevier, 2015)
    The relatively random spiking times of individual neurons provide a source of noise in the brain. We show how this noise interacting with altered depth in the basins of attraction of networks involved in short-term memory, ...
  • Mochol, Gabriela; Hermoso Mendizabal, Ainhoa; Sakata, Shuzo; Harris, Kenneth D.; De la Rocha, Jaime (National Academy of Sciences, 2015)
    The spiking activity of cortical neurons is highly variable. This variability is generally correlated among nearby neurons, an effect commonly interpreted to reflect the coactivation of neurons due to anatomically shared ...
  • Cabral, Joana R. B.; Fernandes, Henrique M.; Van Hartevelt, Tim J.; James, Anthony C.; Kringelbach, Morten L.; Deco, Gustavo (American Institute of Physics (AIP), 2013)
    The neuropathology of schizophrenia remains unclear. Some insight has come from modern/nneuroimaging techniques, which offer an unparalleled opportunity to explore/nin vivo/nthe structure/nand function of the brain. Using ...
  • Ton, Robert; Deco, Gustavo; Daffertshofer, Andreas (Public Library of Science (PLoS), 2014)
    The discrepancy between structural and functional connectivity in neural systems forms the challenge in understanding/ngeneral brain functioning. To pinpoint a mapping between structure and function, we investigated the ...
  • Costa-jussà, Marta R.; Farrús, Mireia; Mariño Acebal, José B.; Fonollosa, José A Rodriguez (Slovak Academy of Sciences, 2012)
    Machine translation systems can be classified into rule-based and corpus-based approaches, in terms of their core methodology. Since both paradigms have been largely used during the last years, one of the aims in the ...
  • Farrús, Mireia; Costa-jussà, Marta R.; Popovic, Maja (Wiley, 2011)
    Evaluation of machine translation output is an important task. Various human evaluation techniques as well as automatic metrics have been proposed and investigated in the last decade. However, very few evaluation methods ...
  • Michos, Konstantinos; Hernández Leo, Davinia (Elsevier, 2018)
    The field of learning design has extensively studied the use of technology for the authoring of learning activities. However, the social dimension of the learning design process is still underexplored. In this paper, ...
  • Martinez-Maldonado, Roberto; Goodyear, Peter; Carvalho, Lucila; Thompson, Kate; Hernández Leo, Davinia; Dimitriadis, Yannis; Prieto, Luis P.; Wardak, Dewa (Elsevier, 2017)
    Across a broad range of design professions, there has been extensive research on design practices and considerable progress in creating new computer-based systems that support design work. Our research is focused on ...
  • Schoonenboom, Judith; Sligte, Henk; Moghnie, Ayman; Hernández Leo, Davinia; Stefanov, Krassen; Glahn, Christian; Specht, Marcus; Lemmers, Ruud (International Association of Online Engineering (IAOE), 2008)

  • Janer Mestres, Jordi; Finney, Nathaniel; Roma Trepat, Gerard; Kersten, Stefan; Serra, Xavier (2009)
    The computer-assisted design of soundscapes for virtual environments has received far less attention than the creation of graphical content. In this “think piece” we briefly introduce the principal characteristics of a ...
