    • Channel coding for joint colour and depth segmentation 

      Wallenberg, Markus; Felsberg, Michael; Forssen, Per-Erik; Dellen, Babette (Springer, 2011)
      Conference report

      Segmentation is an important preprocessing step in many applications. Compared to colour segmentation, fusion of colour and depth greatly improves the segmentation result. Such a fusion is easy to do by stacking ...
    • Differential susceptibility to noise of mixed Turing and Hopf modes in a photosensitive chemical medium 

      Alonso Muñoz, Sergio; Míguez, David G.; Sagués Mestres, Francesc (2007-12-31)
      Article
      Open Access
      We report on experiments with the photosensitive chlorine dioxide-iodine-malonic acid reaction (CDIMA) when forced with a random (spatiotemporally) distributed illumination. Acting on a mixed mode consisting of oscillating ...
    • Generalized median graph computation by means of graph embedding in vector spaces 

      Ferrer Sumsi, Miquel; Valveny, Ernest; Serratosa Casanelles, Francesc; Riesen, Kaspar; Bunke, Horst (2010)
      Article
      Restricted access - publisher's policy
      The median graph has been presented as a useful tool to represent a set of graphs. Nevertheless its computation is very complex and the existing algorithms are restricted to use limited amount of data. In this paper we ...
    • Generalized median string computation by means of string embedding in vector spaces 

      Jiang, Xiaoyi; Wentker, Jöran; Ferrer Sumsi, Miquel (2012-11-01)
      Article
      Restricted access - publisher's policy
      In structural pattern recognition the median string has been established as a useful tool to represent a set of strings. However, its exact computation is complex and of high computational burden. In this paper we propose ...
    • Median graph: a new exact algorithm using a distance based on the maximum common subgraph 

      Ferrer Sumsi, Miquel; Valveny, Ernest; Serratosa Casanelles, Francesc (2009)
      Article
      Restricted access - publisher's policy
      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 ...
    • Paper-based microfluidic sensing devices fabricated by inkjet printing technology 

      Guirao Expósito, Bernat (Universitat Politècnica de Catalunya / Keio University, 2010)
      Master thesis (pre-Bologna period)
      Open Access
      The detection of some analytes, for example heavy metal ions, is crucial in locations such as developing countries or humanitarian emergencies, where no qualified professionals or sophisticated equipment is available. In ...
