    Every 3 seconds, someone develops dementia worldwide. Brain-training exercises, preferably involving also physical activity, have shown their potential to monitor and improve the brain function of people affected by Alzheimer ...
  • Online learning and detection of faces with low human supervision 

    Villamizar Vergel, Michael Alejandro; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (Springer, 2019)
    Article
    Open Access
    We present an efficient,online,and interactive approach for computing a classifier, called Wild Lady Ferns (WiLFs), for face learning and detection using small human supervision. More precisely, on the one hand, WiLFs ...
  • Using a new high-throughput video-tracking platform to assess behavioural changes in Daphnia magna exposed to neuro-active drugs 

    Simão, Fátima C.P.; Martínez Jerónimo, Fernando; Blasco Gutiérrez, Víctor; Moreno-Noguer, Francesc; Porta Pleite, Josep Maria; Pestana, Joao; Soarez, Amadeu; Raldúa Pérez, Demetrio José; Barata Martí, Carlos (Elsevier, 2019-04-20)
    Article
    Open Access
    One of the major challenges that faces today regulatory risk assessment is to speed up the way of assessing threshold sublethal detrimental effects of existing and new chemical products. Recently advances in imaging allows ...
  • Detailed 3D face reconstruction from a single RGB image 

    Rotger Moll, Gemma; Moreno-Noguer, Francesc; Lumbreras, Felipe; Agudo Martínez, Antonio (2019-01-01)
    Article
    Open Access
    This paper introduces a method to obtain a detailed 3D reconstruction of facial skin from a single RGB image. To this end, we propose the exclusive use of an input image without requiring any information about the observed ...
  • A review and comparison of ontology-based approaches to robot autonomy 

    Olivares Alarcos, Alberto; Bebler, Daniel; Khamis, Alaa; Goncalves, Paulo; Habib, Maki K.; Bermejo Alonso, Julita; Barreto, Marcoss; Diab, Mohammed; Rosell Gratacòs, Jan; Quintas, João; Olszewska, Joanna; Nakawala, Hirenkumar; Pignaton de Freitas, Edison; Gyrard, Amelie; Borgo, Stefano; Alenyà Ribas, Guillem; Beetz, Michael; Li, Howard (2019-01-01)
    Article
    Open Access
    Within the next decades, robots will need to be able to execute a large variety of tasks autonomously in a large variety of environments. To relax the resulting programming effort, a knowledge-enabled approach to robot ...
  • Practical resolution methods for MDPs in robotics exemplified with disassembly planning 

    Suárez Hernández, Alejandro; Torras, Carme; Alenyà Ribas, Guillem (Institute of Electrical and Electronics Engineers (IEEE), 2019-07-01)
    Article
    Open Access
    In this paper we focus on finding practical resolution methods for Markov Decision Processes (MDPs) in robotics. Some of the main difficulties of applying MDPs to real-world robotics problems are: (1) having to deal with ...
  • On Cayley's factorization with an application to the orthonormalization of noisy rotation matrices 

    Sarabandi, Soheil; Pérez Gracia, Alba; Thomas, Federico (2019-05-09)
    Article
    Open Access
    A real orthogonal matrix representing a rotation in four dimensions can be decomposed into the commutative product of a left- and a right-isoclinic rotation matrix. This operation, known as Cayley's factorization, directly ...
  • Exploiting symmetries in reinforcement learning of bimanual robotic tasks 

    Amadio, Fabio; Colomé Figueras, Adrià; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Article
    Open Access
    Movement Primitives (MPs) have been widely adopted for representing and learning robotic movements using Reinforcement Learning Policy Search. Probabilistic Movement Primitives (ProMPs) are a kind of MP based on a stochastic ...
  • On inferring intentions in shared tasks for industrial collaborative robots 

    Olivares Alarcos, Alberto; Foix Salmerón, Sergi; Alenyà Ribas, Guillem (2019)
    Article
    Open Access
    Inferring human operators' actions in shared collaborative tasks, plays a crucial role in enhancing the cognitive capabilities of industrial robots. In all these incipient collaborative robotic applications, humans and ...
  • Assistive robotics: research challenges and ethics education initiatives 

    Torras, Carme (2019)
    Article
    Open Access
    Assistive robotics is a fast growing field aimed at helping healthcarers in hospitals, rehabilitation centers and nursery homes, as well as empowering people with reduced mobility at home, so that they can autonomously ...
  • Robust spatio-temporal clustering and reconstruction of multiple deformable bodies 

    Agudo Martínez, Antonio; Moreno-Noguer, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2019-04-01)
    Article
    Open Access
    In this paper we present an approach to reconstruct the 3D shape of multiple deforming objects from a collection of sparse, noisy and possibly incomplete 2D point tracks acquired by a single monocular camera. Additionally, ...
  • Shape basis interpretation for monocular deformable 3D reconstruction 

    Agudo Martínez, Antonio; Moreno-Noguer, Francesc (2019)
    Article
    Open Access
    In this paper, we propose a novel interpretable shape model to encode object non-rigidity. We first use the initial frames of a monocular video to recover a rest shape, used later to compute a dissimilarity measure based ...
