  • Random clustering ferns for multimodal object recognition 

    Villamizar Vergel, Michael Alejandro; Garrell Zulueta, Anais; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (2017-09-01)
    Article
    Accés obert
    We propose an efficient and robust method for the recognition of objects exhibiting multiple intra-class modes, where each one is associated with a particular object appearance. The proposed method, called random clustering ...
  • 3D human pose tracking priors using geodesic mixture models 

    Simo Serra, Edgar; Torras, Carme; Moreno-Noguer, Francesc (2017-04-01)
    Article
    Accés obert
    We present a novel approach for learning a finite mixture model on a Riemannian manifold in which Euclidean metrics are not applicable and one needs to resort to geodesic distances consistent with the manifold geometry. ...
  • Dual REPS: a generalization of relative entropy policy search exploiting bad experiences 

    Colomé Figueras, Adrià; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2017-08-01)
    Article
    Accés obert
    Policy search (PS) algorithms are widely used for their simplicity and effectiveness in finding solutions for robotic problems. However, most current PS algorithms derive policies by statistically fitting the data from the ...
  • Teaching robot’s proactive behavior using human assistance 

    Garrell Zulueta, Anais; Villamizar Vergel, Michael Alejandro; Moreno-Noguer, Francesc; Sanfeliu Cortés, Alberto (2017)
    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 ...
  • Assistent(e)s robòtiqu(e)s: un punt de confluència entre tecnociència i humanitats 

    Torras, Carme (2017)
    Article
    Accés obert
    La robòtica industrial està donant pas a una robòtica de caire més social i assistencial. Simplificant, podríem dir que mentre els robots industrials han ocupat llocs de treball que requereixen manipular materials rígids ...
  • Guest editorial: sensorimotor contingencies for cognitive robotics 

    Alenyà Ribas, Guillem; Tellez Lara, Ricardo; O'Regan, Kevin; Angulo Bahón, Cecilio (Institute of Electrical and Electronics Engineers (IEEE), 2017-06-09)
    Article
    Accés obert
    The sensorimotor approach to cognition states, that the key to bring semantics to the world of a robot, requires making the robot learn the relation between the actions that the robot performs and the change it experiences ...
  • Efficient interactive decision-making framework for robotic applications 

    Agostini, Alejandro Gabriel; Torras, Carme; Woergoetter, Florentin (2017-06-01)
    Article
    Accés obert
    The inclusion of robots in our society is imminent, such as service robots. Robots are now capable of reliably manipulating objects in our daily lives but only when combined with artificial intelligence (AI) techniques for ...
  • Combining local-physical and global-statistical models for sequential deformable shape from motion 

    Agudo Martínez, Antonio; Moreno-Noguer, Francesc (2017-04-01)
    Article
    Accés obert
    In this paper, we simultaneously estimate camera pose and non-rigid 3D shape from a monocular video, using a sequential solution that combines local and global representations. We model the object as an ensemble of particles, ...
  • Modal space: a physics-based model for sequential estimation of time-varying shape from monocular video 

    Agudo Martínez, Antonio; Martinez Montiel, José Maria; Agapito, Lourdes; Calvo, Begoña (2017-01-01)
    Article
    Accés obert
    This paper describes two sequential methods for recovering the camera pose together with the 3D shape of highly deformable surfaces from a monocular video. The nonrigid 3D shape is modeled as a linear combination of mode ...
  • Real-time 3D reconstruction of non-rigid shapes with a single moving camera 

    Agudo Martínez, Antonio; Moreno-Noguer, Francesc; Calvo, Begoña; Martinez Montiel, José Maria (2016)
    Article
    Accés obert
    This paper describes a real-time sequential method to simultaneously recover the camera motion and the 3D shape of deformable objects from a calibrated monocular video. For this purpose, we consider the Navier-Cauchy ...
  • A bayesian approach to simultaneously recover camera pose and non-rigid shape from monocular images 

    Moreno-Noguer, Francesc; Porta Pleite, Josep Maria (2016)
    Article
    Accés obert
    In this paper we bring the tools of the Simultaneous Localization and Map Building (SLAM) problem from a rigid to a deformable domain and use them to simultaneously recover the 3D shape of non-rigid surfaces and the sequence ...
  • A 3D descriptor to detect task-oriented grasping points in clothing 

    Ramisa Ayats, Arnau; Alenyà Ribas, Guillem; Moreno-Noguer, Francesc; Torras, Carme (2016)
    Article
    Accés obert
    Manipulating textile objects with a robot is a challenging task, especially because the garment perception is difficult due to the endless configurations it can adopt, coupled with a large variety of colors and designs. ...
