    • Motion analysis of image sequences using connected operators 

      Garrido Ostermann, Luis; Oliveras Vergés, Albert; Salembier Clairon, Philippe Jean (International Society for Photo-Optical Instrumentation Engineers (SPIE), 1997)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper deals with a class of morphological operators called connected operators. These operators interact with the signal by merging flat zones. As a results, they do not create any new contours and are very attractive ...

    • Motion connected operators for image sequences 

      Salembier Clairon, Philippe Jean; Oliveras Vergés, Albert; Garrido Ostermann, Luis (1996)
      Text en actes de congrés
      Accés obert
      This paper deals with motion-oriented connected operators. These operators eliminate from an original sequence the components that do not undergo a specific motion (defined as a filtering parameter). As any connected ...

    • Multiclass cancer-microarray classification algorithm with Pair-Against-All redundancy 

      Bosio, Mattia; Bellot Pujalte, Pau; Salembier Clairon, Philippe Jean; Oliveras Vergés, Albert (2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Multiclass cancer classification is still a challenging task in the field of machine learning. A novel multiclass approach is proposed in this work as a combination of multiple binary classifiers. It is an example of Error ...

    • NetBenchmark: a bioconductor package for reproducible benchmarks of gene regulatory network inference 

      Bellot Pujalte, Pau; Olsen, Catharina; Salembier Clairon, Philippe Jean; Oliveras Vergés, Albert; Meyer, Patrick E. (2015-09-29)
      Article
      Accés obert
      Background: In the last decade, a great number of methods for reconstructing gene regulatory networks from expression data have been proposed. However, very few tools and datasets allow to evaluate accurately and reproducibly ...

    • Practical extensions of connected operators 

      Oliveras Vergés, Albert; Salembier Clairon, Philippe Jean (KLUWER ACADEMIC PUB. KLUWER ACADEMIC PUBLISHERS, 1996)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper deals with the notion of connected operators. These operators are becoming popular in image processing because they have the fundamental property of simplifying the signal while preserving the contour information. ...

    • Processament del senyal - Col.lecció de Problemes 

      Hernando Pericás, Francisco Javier; Lagunas Hernandez, Miguel A.; Marqués Acosta, Fernando; Mariño Acebal, José Bernardo; Monte Moreno, Enrique; Nadeu Camprubí, Climent; Oliveras Vergés, Albert; Rodríguez Fonollosa, Javier; Torres Urgell, Lluís; Vázquez Grau, Gregorio; Vidal Manzano, José (Universitat Politècnica de Catalunya, 2003)

    • Simbad: a tool for speech analysis and synthesis 

      Nadeu Camprubí, Climent; Mariño Acebal, José Bernardo; Oliveras Vergés, Albert (1990)
      Text en actes de congrés
      Accés obert
      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 ...

    • Stereo image analysis using connected operators 

      Oliveras Vergés, Albert; Salembier Clairon, Philippe Jean; Garrido Ostermann, Luis (IEEE IEEE, 1997)
      Text en actes de congrés
      Accés obert
      Connected operators are increasingly used in image processing due to their properties of simplifying the image with various criteria, without loosing contour's information. These properties are related to the connected ...

    • Study of normalization and aggregation approaches for consensus network estimation 

      Bellot Pujalte, Pau; Salembier Clairon, Philippe Jean; Oliveras Vergés, Albert; Meyer, Patrick (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Inferring gene regulatory networks from expression data is a very difficult problem that has raised the interest of the scientific community. Different algorithms have been proposed to try to solve this issue, but it has ...

    • Two level continuous speech recognition using demisyllable-based HMM word spotting 

      Lleida Solano, Eduardo; Mariño Acebal, José Bernardo; Nadeu Camprubí, Climent; Oliveras Vergés, Albert (1991)
      Text en actes de congrés
      Accés obert
      This paper describes a two level Spanish Continuous Speech Recognition System based on Demisyllable HMM modelling, word-spotting and finite-state lexical and syntactic knowledge. The first level, the word level, is based ...
