    Conference report
    Open Access
    Se presenta en este artículo un material docente para la enseñanza de las señales y los sistemas analógicos. El enfoque que se ha dado es eminentemente aplicado. Se presenta un conjunto muy completo de ejercicios, problemas ...
  • Improving spatial codification in semantic segmentation 

    Ventura Royo, Carles; Giró Nieto, Xavier; Vilaplana Besler, Verónica (2015)
    Conference report
    Restricted access - publisher's policy
    This paper explores novel approaches for improving the spatial codification for the pooling of local descriptors to solve the semantic segmentation problem. We propose to partition the image into three regions for each ...
  • Automatic left ventricular contour extraction for volume calculation from echocardiographic images 

    Gasull Llampallas, Antoni; Torres Urgell, Lluís; Marqués Acosta, Fernando; Vázquez Grau, Gregorio (1989)
    Conference report
    Open Access
    This paper presents a new fully automated algorithm that extracts LV epicardial and endocardial borders from 2-D echocardiograms. The method is based on a radial search approach, which is the best way to use some a priori ...
  • Classical methods of left ventricular contour extraction and preprocessing of echocardiographic images: a review 

    Torres Urgell, Lluís; Gasull Llampallas, Antoni; Marqués Acosta, Fernando (1989)
    Conference report
    Open Access
    A main objective of digital processing of echocardiographic images is to improve the signal to noise ratio of the video images acquired from the ultrasound equipment along with contour extraction in order to obtain cardiac ...
  • Análisis espectral de series meteorológicas 

    Nadeu Camprubí, Climent; Gasull Llampallas, Antoni; Figueiras Vidal, Aníbal R. (1981)

  • Simbad: a tool for speech analysis and synthesis 

    Nadeu Camprubí, Climent; Mariño Acebal, José Bernardo; Oliveras Vergés, Albert (1990)
    Conference report
    Open Access
    SIMBAD has been developed to facilitate the tasks involved in the design of a concatenative speech synthesis system: 1) building a dictionary of parameterized speech units, and 2) obtaining a set of rules to concatenate ...
  • Constant variance transversal filtering for adaptive channel equalization 

    Vázquez Grau, Gregorio; Gasull Llampallas, Antoni; Sanchez, J J; Lagunas Hernandez, Miguel A. (1989)
    Conference report

  • Use of the available information for adequate step-size actualization 

    Vázquez Grau, Gregorio; Gasull Llampallas, Antoni (1987)
    Conference report
    Open Access
    This paper deals with the use of the available information for the update of the step-size in gradient-based adaptive methods. Several proposals are made and due to the relatively high computational cost, more efficient ...
