Sumari

  • Fuzzy systems and neural networks XML schemas for soft computing 

    Rodríguez de Soto, Adolfo; Capdevila, Conrado A.; Fernandez, Eva Cuervo (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2003)
    Article
    Accés obert
    This article presents an XML[2] based language for the specification of objects in the Soft Computing area. The design promotes reuse and takes a compositional approach in which more complex constructs are built from simpler ...

  • Introducing FDSA (Fuzzy Dictionary of Synonyms and Antonyms): applications on information retrieval and stand-alone use 

    Fernández Lanza, Santiago; Graña, Jorge; Sobrino Cerdeiriña, Alejandro (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2003)
    Article
    Accés obert
    We start by analyzing the role of imprecision in information retrieval in the Web, some theoretical contributions for managing this problem and its presence in search engines, with special emphasis on the use of thesaurus ...

  • Fuzzy sets in computer vision: an overview 

    Sobrevilla Frisón, Pilar; Montseny Masip, Eduard (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2003)
    Article
    Accés obert
    Every computer vision level crawl with uncertainty, what makes its management a significant problem to be considered and solved when trying for automated systems for scene analysis and interpretation. This is why fuzzy set ...

  • Fuzzy morphological operators in image processing 

    Burillo López, Pedro; Frago Paños, Noé; Fuentes-González, Ramón (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2003)
    Article
    Accés obert
    First of all, in this paper we propose a family of fuzzy implication operators, which the generalised Luckasiewicz's one, and to analyse the impacts of Smets and Magrez properties on these operators. The result of this ...

  • Segmenting colour images on the basis of a fuzzy hierarchical approach 

    Chamorro Martínez, Jesús; Sánchez Fernández, Daniel; Prados Suárez, Belen; Galán Perales, Elena; Vila Miranda, María Amparo (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica., 2003)
    Article
    Accés obert
    In this paper we deal with two problems related to imprecision in colour image segmentation processes: to decide whether a set of pixels verify the property "to be homogeneously coloured", and to represent the set of ...

  • Fuzzy approach for data association in image tracking 

    García, Jesús; Molina, José Manuel; Besada, Juan Alberto; Portillo García, Javier Ignacio (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2003)
    Article
    Accés obert
    A fuzzy system has been developed to ponder update decisions both for the trajectories and shapes estimated for targets. It is embedded in an A-SMGCS Surveillance function for airport surface, based on video data processing, ...

  • Visual anomaly detection via soft computing: a prototype application at NASA 

    Domínguez, Jesús A.; Klinko, Steve (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2003)
    Article
    Accés obert
    A visual system prototype that detects anomalies or defects in real time under normal lighting operating conditions was built for NASA at the Kennedy Space Center (KSC). The system prototype is basically a learning machine ...

  • Spectral fuzzy classification: a supervised approach 

    Amo, Ana del; Gómez González, Daniel; Montero de Juan, Francisco Javier (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2003)
    Article
    Accés obert
    The goal of this paper is to present an algorithm for pattern recognition, leveraging on an existing fuzzy clustering algorithm developed by Del Amo et al. [3, 5], and modifying it to its supervised version, in order to ...

  • Innovative applications of associative morphological memories for image processing and pattern recognition 

    Graña, Manuel; Sussner, Peter; Ritter, Gerhard (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2003)
    Article
    Accés obert
    Morphological Associative Memories have been proposed for some image denoising applications. They can be applied to other less restricted domains, like image retrieval and hyper spectral image unsupervised segmentation. ...
