  • A real-time human-robot interaction system based on gestures for assistive scenarios 

    Canal Camprodon, Gerard; Escalera, Sergio; Angulo Bahón, Cecilio (2016)
    Article
    Accés restringit per política de l'editorial
    Natural and intuitive human interaction with robotic systems is a key point to develop robots assisting people in an easy and effective way. In this paper, a Human Robot Interaction (HRI) system able to recognize gestures ...
  • Exact interval propagation for the efficient solution of position analysis problems on planar linkages 

    Celaya Llover, Enric; Creemers, Tom Lambert; Ros Giralt, Lluís (2012)
    Article
    Accés obert
    This paper presents an interval propagation algorithm for variables in planar single-loop linkages. Given intervals of allowed values for all variables, the algorithm provides, for every variable, the whole set of values, ...
  • Evaluating the use of robots to enlarge AAL services 

    Angulo Bahón, Cecilio; Pfeiffer, Sammy; Alenyà Ribas, Guillem; Téllez Lara, Ricardo (2015-01-01)
    Article
    Accés obert
    We introduce robots as a tools to enhance Ambient Assisted Living (AAL) services. Robots are a unique opportunity to create new systems to cooperate in reaching better living conditions. Robots offer the possibility of ...
  • Service robots for citizens of the future 

    Torras, Carme (2015)
    Article
    Accés obert
    Robots are no longer confined to factories; they are progressively spreading to urban, social and assistive domains. In order to become handy co-workers and helpful assistants, they must be endowed with quite different ...
  • MSClique: Multiple structure discovery through the maximum weighted clique problem 

    Sanromà Güell, Gerard; Peñate Sánchez, Adrián; Alquézar Mancho, René; Serratosa Casanelles, Francesc; Moreno-Noguer, Francesc; Andrade-Cetto, Juan; González Ballester, Miguel Ángel (2016-01-01)
    Article
    Accés obert
    We present a novel approach for feature correspondence and multiple structure discovery in computer vision. In contrast to existing methods, we exploit the fact that point-sets on the same structure usually lie close to ...
  • Variable symmetry breaking in numerical constraint problems 

    Goldsztejn, Alexandre; Jermann, Christophe; Ruiz de Angulo García, Vicente; Torras, Carme (2015)
    Article
    Accés restringit per política de l'editorial
    Symmetry breaking has been a hot topic of research in the past years, leading to many theoretical developments as well as strong scaling strategies for dealing with hard applications. Most of the research has however focused ...
  • DaLI: deformation and light invariant descriptor 

    Simó Serra, Edgar; Torras, Carme; Moreno-Noguer, Francesc (2015-11-01)
    Article
    Accés obert
    Recent advances in 3D shape analysis and recognition have shown that heat diffusion theory can be effectively used to describe local features of deforming and scaling surfaces. In this paper, we show how this description ...
  • Growth signatures of rosette plants from time-lapse video 

    Dellen, Babette Karla Margarete; Scharr, Hanno; Torras, Carme (2015)
    Article
    Accés obert
    Plant growth is a dynamic process, and the precise course of events during early plant development is of major interest for plant research. In this work, we investigate the growth of rosette plants by processing time-lapse ...
  • Planning robot manipulation to clean planar surfaces 

    Martínez Martínez, David; Alenyà Ribas, Guillem; Torras, Carme (2015)
    Article
    Accés obert
    This paper presents a new approach to plan high-level manipulation actions for cleaning surfaces in household environments, like removing dirt from a table using a rag. Dragging actions can change the distribution of dirt ...
  • Closed-loop inverse kinematics for redundant robots: comparative assessment and two enhancements 

    Colomé Figueras, Adrià; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Article
    Accés obert
    Motivated by the need of a robust and practical Inverse Kinematics (IK) algorithm for the WAM robot arm, we reviewed the most used Closed-Loop IK (CLIK) methods for redundant robots, analysing their main points of concern: ...
