  • 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 ...
  • Teaching robot's proactive behavior using human assistance 

    Garrell Zulueta, Anais; Villamizar Vergel, Michael Alejandro; Moreno-Noguer, Francesc; Sanfeliu Cortés, Alberto (2017-04-01)
    Article
    Accés obert
    In recent years, there has been a growing interest in enabling autonomous social robots to interact with people. However, many questions remain unresolved regarding the social capabilities robots should have in order to ...
  • Detection and positioning of pipes and columns with autonomous multicopter drones 

    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) ...
  • Cooperative monocular-based SLAM for multi-UAV systems in GPS-denied environments 

    Trujillo, Juan Carlos; Munguía Alcalá, Rodrigo Francisco; Guerra Paradas, Edmundo; Grau Saldes, Antoni (Multidisciplinary Digital Publishing Institute (MDPI), 2018-04-26)
    Article
    Accés obert
    This work presents a cooperative monocular-based SLAM approach for multi-UAV systems that can operate in GPS-denied environments. The main contribution of the work is to show that, using visual information obtained from ...
  • Uncalibrated visual servo for unmanned aerial manipulation 

    Santamaria Navarro, Àngel; Grosch Obregon, Patrick John; Lippiello, Vincenzo; Solà Ortega, Joan; Andrade-Cetto, Juan (Institute of Electrical and Electronics Engineers (IEEE), 2017-08-01)
    Article
    Accés obert
    This paper addresses the problem of autonomous servoing an unmanned redundant aerial manipulator using computer vision. The overactuation of the system is exploited by means of a hierarchical control law, which allows to ...
  • Boosted Random ferns for object detection 

    Villamizar Vergel, Michael Alejandro; Andrade-Cetto, Juan; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (2018-02-01)
    Article
    Accés obert
    In this paper we introduce the Boosted Random Ferns (BRFs) to rapidly build discriminative classifiers for learning and detecting object categories. At the core of our approach we use standard random ferns, but we introduce ...
  • La evaluación continua: una aportación a como corregir algunos efectos negativos 

    Domingo Peña, Joan; Segura Casanovas, Joan; Grau Saldes, Antoni (2018-01)
    Article
    Accés obert
  • Systematic analysis of primary sequence domain segments for the discrimination between class C GPCR subtypes 

    König, Caroline; Alquézar Mancho, René; Vellido Alcacena, Alfredo; Giraldo Arjonilla, Jesús (2018-03-01)
    Article
    Accés restringit per política de l'editorial
    G-protein-coupled receptors (GPCRs) are a large and diverse super-family of eukaryotic cell membrane proteins that play an important physiological role as transmitters of extracellular signal. In this paper, we investigate ...
  • A proposal to develop and assess professional skills in Engineering Final Year Projects 

    Sánchez Carracedo, Fermín; Climent Vilaró, Joan; Corbalán González, Julita; Fonseca Casas, Pau; García Almiñana, Jordi; Herrero Zaragoza, José Ramón; Rodríguez Hontoria, Horacio; Sancho Samsó, María Ribera (Tempus Publications, 2018-03)
    Article
    Accés restringit per política de l'editorial
    In this paper we discuss the result of piloting a methodology for Engineering Final Year Projects (FYP) assessment that takes into consideration professional skills acquisition. The FYP is structured around three milestones; ...
  • Gain-scheduling multivariable LPV control of an irrigation canal system 

    Bolea Monte, Yolanda; Puig Cayuela, Vicenç (2016-07)
    Article
    Accés obert
    The purpose of this paper is to present a multivariable linear parameter varying (LPV) controller with a gain scheduling Smith Predictor (SP) scheme applicable to open-flow canal systems. This LPV controller based on SP ...
