  • 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 ...
  • Performance of trellis-coded 8-DPSK modulation with co-channel interference in land mobile radio channels 

    Femenias Nadal, Guillem; Agustí Comes, Ramon (Institute of Electrical and Electronics Engineers (IEEE), 1989)
    Conference report
    Open Access
    The BER (bit error rate) performance of uncoded 4-DPSK (differential phase shift keying) and coded 8-DPSK (with 8 and 16 state codes) modulation schemes have been studied. A Rayleigh mobile channel and the presence of ...
  • 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 ...
  • Subband splitting, adaptive scalar prediction and vector quantization for speech coding 

    Masgrau Gómez, Enrique José; Rodríguez Fonollosa, José Adrián; Mariño Acebal, José Bernardo (1988)
    Conference report
    Open Access
    This paper describes a new coding structure based on the combination of Vector Quantizati.on, Linear Prediction l)nd Subband Splitting that achieves high guality speech at rates below 10 Kbit/sec. In this scheme, a vector ...
  • Integration of MIRAS breadboard and future activities 

    Martín Neira, Manuel; Goutoule, J.M.; Knight, A.; Claude, J.; Bará Temes, Francisco Javier; Camps Carmona, Adriano José; Torres Torres, Francisco; Corbella Sanahuja, Ignasi; Lannes, A.; Anterrieu, E.; Laursen, B.; Skou, N. (1996)
    Conference report
    Open Access
    The European Space Agency (ESA) is conducting a feasibility study on MIRAS, a Microwave Imaging Radiometer using two dimensional aperture synthesis, for the mapping of soil moisture and ocean salinity from space. An aircraft ...
