    Article
    Open Access
    Drone monitoring plays an irreplaceable and significant role in forest firefighting due to its characteristics of wide-range observation and real-time messaging. However, aerial images are often susceptible to different ...

  • Semi-supervised wildfire smoke detection based on smoke-aware consistency 

    Wang, Chuansheng; Grau Saldes, Antoni; Guerra Paradas, Edmundo; Shen, Zhiguo; Hu, Jinxing; Fan, Haoyi (Frontiers Media SA, 2022-11-08)
    Article
    Open Access
    The semi-transparency property of smoke integrates it highly with the background contextual information in the image, which results in great visual differences in different areas. In addition, the limited annotation of ...

  • A hierarchical framework for collaborative artificial intelligence 

    Crowley, James L; Coutaz, Joëlle; Grosinger, Jasmin; Vázquez Salceda, Javier; Angulo Bahón, Cecilio; Sanfeliu Cortés, Alberto; Iocchi, Luca; Cohn, Anthony G. (2023-01)
    Article
    Open Access
    We propose a hierarchical framework for collaborative intelligent systems. This framework organizes research challenges based on the nature of the collaborative activity and the information that must be shared, with each ...

  • Efficient hand gesture recognition for human-robot interaction 

    Peral Sánchez, Marc; Sanfeliu Cortés, Alberto; Garrell Zulueta, Anais (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Article
    Open Access
    In this paper, we present an efficient and reliable deep-learning approach that allows users to communicate with robots via hand gesture recognition. Contrary to other works which use external devices such as gloves [1] ...

  • Control-oriented estimation of the exchange current density in PEM fuel cells via stochastic filtering 

    Aguilar Plazaola, José Agustín; Andrade-Cetto, Juan; Husar, Attila Peter (2022-08)
    Article
    Open Access
    Increasing efficiency and durability of fuel cells can be achieved through advanced model-based optimal control of its operating conditions, and the efficient online estimation of fuel cell parameters and internal states ...

  • Event-based line SLAM in real-time 

    Chamorro Hernández, William Oswaldo; Solà Ortega, Joan; Andrade-Cetto, Juan (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Article
    Open Access
    Event-based cameras generate asynchronous streams of events, triggered proportionally to the logarithmic change of brightness in the scene. These cameras have very low latency and high dynamic range suitable to address ...

  • WOLF: A modular estimation framework for robotics based on factor graphs 

    Solà Ortega, Joan; Vallvé Navarro, Joan; Casals, Joaquim; Deray, Jeremie; Fourmy, Mederic; Atchuthan, Dinseh; Corominas Murtra, Andreu; Andrade-Cetto, Juan (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Article
    Open Access
    This paper introduces WOLF, a C++ estimation framework based on factor graphs and targeted at mobile robotics. WOLF can be used beyond SLAM to handle self-calibration, model identification, or the observation of dynamic ...

  • Trends and Characteristics of Emergency Medical Services in Italy: A 5-Years Population-Based Registry Analysis 

    Campagna, Sara; Conti, Andrea; Starnini, Michele; Dalmasso Blanch, Marc; Gianino, Maria Michela; Borraccino, Alberto (2020-12-11)
    Article
    Open Access
    Background: Emergency Medical Services (EMS) plays a fundamental role in providing good quality healthcare services to citizens, as they are the first responders in distressing situations. Few studies have used available ...

  • Dual-branch CNNs for vehicle detection and tracking on LiDAR data 

    Vaquero Gómez, Víctor; del Pino Bastida, Iván; Moreno-Noguer, Francesc; Solà Ortega, Joan; Sanfeliu Cortés, Alberto; Andrade-Cetto, Juan (2021-11-01)
    Article
    Open Access
    We present a novel vehicle detection and tracking system that works solely on 3D LiDAR information. Our approach segments vehicles using a dual-view representation of the 3D LiDAR point cloud on two independently trained ...

    González Romero, Alejandro; Alquézar Mancho, René; Ramírez Flores, Arturo; González Acuña, Francisco; García Olmedo, Ian (2022-02-16)
    Article
    Open Access
    The game of Scrabble has been successfully tackled by two engines: Quackle and Maven. They attain the state-of-the-art in Computer Scrabble. These engines use simulation techniques and precalculated values to achieve ...

  • A hybrid visual-based SLAM architecture: local filter-based SLAM with keyframe-based global mapping 

    Munguía Alcalá, Rodrigo Francisco; Trujillo, Juan Carlos; Guerra Paradas, Edmundo; Grau Saldes, Antoni (Multidisciplinary Digital Publishing Institute (MDPI), 2021-12-29)
    Article
    Open Access
    This work presents a hybrid visual-based SLAM architecture that aims to take advantage of the strengths of each of the two main methodologies currently available for implementing visual-based SLAM systems, while at the ...

  • Social robot navigation tasks: combining machine learning techniques and social force model
