    • Median graph computation by means of a genetic approach based on minimum common supergraph and maximum common subraph 

      Ferrer Sumsi, Miquel; Valveny, Ernest; Serratosa Casanelles, Francesc (Springer Berlin / Heidelberg, 2009)
      Capítol de llibre
      Accés restringit per política de l'editorial
      Given a set of graphs, the median graph has been theoretically presented as a useful concept to infer a representative of the set. However, the computation of the median graph is a highly complex task and its practical ...
    • Median graph: a new exact algorithm using a distance based on the maximum common subgraph 

      Ferrer Sumsi, Miquel; Valveny, Ernest; Serratosa Casanelles, Francesc (2009)

      Accés restringit per política de l'editorial
      Median graphs have been presented as a useful tool for capturing the essential information of a set of graphs. Nevertheless, computation of optimal solutions is a very hard problem. In this work we present a new and more ...

    • Segmentation robust to the vignette effect for machine vision systems 

      Karatzas, D; Rusiñol, Marçal; Antens, Coen; Ferrer Sumsi, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2008)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The vignette effect (radial fall-off) is commonly encountered in images obtained through certain image acquisition setups and can seriously hinder automatic analysis processes. In this paper we present a fast and efficient ...
