    König, Caroline; Shaim, Ilmira; Vellido Alcacena, Alfredo; Romero Merino, Enrique; Alquézar Mancho, René; Giraldo Arjonilla, Jesús (Nature, 2018-07-05)
    Article
    Accés obert
    Biocuration in the omics sciences has become paramount, as research in these fields rapidly evolves towards increasingly data-dependent models. As a result, the management of web-accessible publicly-available databases ...
  • Graph SLAM sparsification with populated topologies using factor descent optimization 

    Vallvé Navarro, Joan; Solà Ortega, Joan; Andrade-Cetto, Juan (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Article
    Accés obert
    Current solutions to the simultaneous localization and mapping (SLAM) problem approach it as the optimization of a graph of geometric constraints. Scalability is achieved by reducing the size of the graph, usually in two ...

    Guerra Paradas, Edmundo; Munguía Alcalá, Rodrigo Francisco; Bolea Monte, Yolanda; Grau Saldes, Antoni (2018-06-21)
    Article
    Accés obert
    A multimodal sensory array to accurately position aerial multicopter drones with respect to pipes has been studied, and a solution exploiting both LiDAR and vision sensors has been proposed. Several challenges, including ...
  • Human action recognition by means of subtensor projections and dense trajectories 

    Carmona Leyva, José María; Climent Vilaró, Joan (2018-09)
    Article
    Accés restringit per política de l'editorial
    In last years, most human action recognition works have used dense trajectories features, to achieve state-of-the-art results. Histograms of Oriented Gradients (HOG), Histogram of Optical Flow (HOF) and Motion Boundary ...
  • Searching and tracking people with cooperative mobile robots 

    Goldhoorn, Alex; Garrell Zulueta, Anais; Alquézar Mancho, René; Sanfeliu Cortés, Alberto (2018)
    Article
    Accés obert
    Social robots should be able to search and track people in order to help them. In this paper we present two different techniques for coordinated multi-robot teams for searching and tracking people. A probability map (belief) ...
