  • Antiextensive connected operators for image and sequence processing 

    Salembier Clairon, Philippe Jean; Oliveras Vergés, Albert; Garrido Ostermann, Luis (1998-04)
    Article
    Open Access
    This paper deals with a class of morphological operators called connected operators. These operators filter the signal by merging its flat zones. As a result, they do not create any new contours and are very attractive for ...
  • Profiling of aerosol microphysical properties at several EARLINET/AERONET sites during the July 2012 ChArMEx/EMEP campaign 

    Granados Muñoz, María José; Navas Guzmán, Francisco; Guerrero Rascado, Juan Luis; Bravo Aranda, Juan Antonio; Binietoglou, Ioannis; Nepomuceno Pereira, Sergio; Basart Alpuente, Sara; Baldasano Recio, José María; Belegante, Livio; Chaikovsky, Anatoli; Comerón Tejero, Adolfo; D'Amico, Giuseppe; Muñoz Porcar, Constantino; Rodríguez, Alejandro; Sicard, Michaël; Nickovic, Slobodan; Papayannis, Alexander; Pappalardo, Gelsomina; Wandinger, Ulla; Alados Arboledas, Lucas (2016-01-01)
    Article
    Open Access
    The simultaneous analysis of aerosol microphysical properties profiles at different European stations is made in the framework of the ChArMEx/EMEP 2012 field campaign (9-11 July 2012). During and in support of this campaign, ...
  • Depth map compression via 3D region-based representation 

    Maceira, Marc; Morros Rubió, Josep Ramon; Ruiz Hidalgo, Javier (2016-07-21)
    Article
    Open Access
    In 3D video, view synthesis is used to create new virtual views between encoded camera views. Errors in the coding of the depth maps introduce geometry inconsistencies in synthesized views. In this paper, a new 3D ...
  • Quantification of survey expectations by means of symbolic regression via genetic programming to estimate economic growth in central and eastern european economies 

    Claveria, Oscar; Monte Moreno, Enrique; Torra Porras, Salvador (2016-03-21)
    Article
    Restricted access - publisher's policy
    Tendency surveys are the main source of agents' expectations. This study has a twofold aim. First, it proposes a new method to quantify survey-based expectations by means of symbolic regression (SR) via genetic programming. ...
  • Modelling cross-dependencies between Spain’s regional tourism markets with an extension of the Gaussian process regression model 

    Claveria, Oscar; Monte Moreno, Enrique; Torra Porras, Salvador (2016-08-16)
    Article
    Open Access
    This study presents an extension of the Gaussian process regression model for multiple-input multiple-output forecasting. This approach allows modelling the cross-dependencies between a given set of input variables and ...
  • A belief-based decision-making framework for spectrum selection in cognitive radio networks 

    Pérez Romero, Jordi; Raschellà, Alessandro; Sallent Roig, José Oriol; Umbert Juliana, Anna (2015-12-17)
    Article
    Open Access
    This paper presents a comprehensive cognitive management framework for spectrum selection in cognitive radio networks. The framework uses a belief vector concept as a means to predict the interference affecting the different ...
  • CEMs and Faraday rotation study of ¿-Fe2O3- Fe3O4films obtained by a new pyrolisis technique 

    Cusidó Fàbregas, Joan Antoni; Obradors Berenguer, Xavier; Fontcuberta, Josep; Isalgue Buxeda, Antonio; Canal Bienzobas, Fernando; Joubert, Jean C.; Langlet, M. (1987-01)
    Article
    Open Access
    Thin film iron oxides prepared by a new pyrolisis technique are studied by means of CEM spectroscopy and Faraday rotation measurements. It is shown that Fe3O4spinel oxides are obtained when the deposition is performed under ...
  • Implementation of cognitive radio networks to evaluate spectrum management strategies in real-time 

    Raschellà, Alessandro; Umbert Juliana, Anna (2016-04-01)
    Article
    Restricted access - publisher's policy
    This paper illustrates a Universal Software Radio Peripheral (USRP)-based real-time testbed that is able to evaluate different spectrum management solutions that exploit the Cognitive Radio (CR) paradigm. The main objective ...
  • Antipodally invariant metrics for fast regression-based super-resolution 

    Pérez-Pellitero, Eduardo; Salvador, Jordi; Ruiz Hidalgo, Javier; Rosenhahn, Bodo (2016-03-31)
    Article
    Open Access
    Dictionary-based super-resolution (SR) algorithms usually select dictionary atoms based on the distance or similarity metrics. Although the optimal selection of the nearest neighbors is of central importance for such ...
  • A contour-based approach to binary shape coding using a multiple grid chain code 

    Nunes, P; Marqués Acosta, Fernando; Pereira, F; Gasull Llampallas, Antoni (2000-05)
    Article
    Open Access
    This paper presents a contour-based approach to efficiently code binary shape information in the context of object-based video coding. This approach meets some of the most important requirements identified for the MPEG-4 ...
