  • Blind beamforming for DS-CDMA systems 

    Pérez Palomar, Daniel; Lagunas Hernandez, Miguel A. (Servicio de Publicaciones Universidad de Vigo, 1999)
    Text en actes de congrés
    Accés obert
    Code Division Multiple Access (CDMA) has been proposed as an efficient access method for cellular and personal communication systems outperforming the classical FDMA and TDMA techniques. But, in contrast to them, CDMA ...
  • A video object generation tool allowing friendly user interaction 

    Marcotegui Iturmendi, Beatriz; Correia Fernandez-Pereira, Paulo; Marqués Acosta, Fernando; Mech, R.; Rosa, R; Wollborn, M; Zanoguera, Francisca (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    In this paper we describe an interactive video object segmentation tool developed in the framework of the ACTS-AC098 MOMUSYS project. The Video Object Generator with User Environment (VOGUE) combines three different sets ...
  • A proposal for dependent optimization in scalabale region-based coding systems 

    Morros, R; Marqués Acosta, Fernando (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    We address in this paper the problem of optimal coding in the framework of region-based video coding systems, with a special stress on content-based functionalities. We present a coding system that can provide scaled layers ...
  • Representing and retrieving regions using binary partition trees 

    Garrido Ostermann, Luis; Salembier Clairon, Philippe Jean; Casas Pla, Josep Ramon (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    This paper discusses the interest of Binary Partition Trees for image and region representation in the context of indexing and similarity based retrieval. Binary Partition Trees concentrate in a compact and structured way ...
  • Speaker recognition using frequency filtered spectral energies 

    Hernando Pericás, Francisco Javier (FONDAZIONE UGO BORDONI, 1999)
    Text en actes de congrés
    Accés obert
    The spectral parameters that result from filtering the frequency sequence of log mel-scaled filter-bank energies with a simple first or second order FIR filter have proved to be an efficient speech representation in ...
  • A second opinion approach for speech recognition verification 

    Hernández-Ábrego, G; Mariño Acebal, José Bernardo (M,I, Torres & A. Sanfeliu / AERFAI, 1999)
    Text en actes de congrés
    Accés obert
    In order to improve the reliability of speech recognition results, a verifying system, that takes profit of the information given from an alternative recognition step is proposed. The alternative results are considered as ...
  • Minimum confusibility training of context dependent demiphones 

    Nogueiras Rodríguez, Albino; Mariño Acebal, José Bernardo (G. Olaszy, G. Németh, K. Erdohegyi, 1999)
    Text en actes de congrés
    Accés obert
    During the last years two different approaches have been widely used in order to improve the acoustic modeling in continuous speech recognition systems: discriminative training algorithms and context dependent subword ...
  • X-Type Interface for Management of Multidomain Multitechnology Networks 

    Serrat Fernández, Juan (Morris Sloman, 1999)
    Text en actes de congrés
    Accés obert
    The specification and implementation of Xcoop interfaces has received great attention in the last few years. In fact, the appropriate design of this system component is a key aspect for efficient and seamless co-operative ...
  • Fuzzy reasoning in confidence evaluation of speech recognition 

    Hernández-Abrego, G; Mariño Acebal, José Bernardo (., 1999)
    Text en actes de congrés
    Accés obert
    Confidence measures represent a systematic way to express reliability of speech recognition results. A common approach to confidence measuring is to take profit of the information that several recognition-related features ...
