  • 3D point cloud video segmentation based on interaction analysis 

    Lin, Xiao; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (Springer, 2016)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    Given the widespread availability of point cloud data from consumer depth sensors, 3D segmentation becomes a promising building block for high level applications such as scene understanding and interaction analysis. It ...

  • Morphological detection based on size and contrast criteria Morphological detection based on size and contrast criteria application to cells detection 

    Salembier Clairon, Philippe Jean; Gasull Llampallas, Antoni; Marqués Acosta, Fernando; Sayrol Clols, Elisa (. IEEE, 1992)
    Text en actes de congrés
    Accés obert
    This paper deals with a detection algorithm relying on size and contrast criteria. It is suitable for a large range of applications where a priori information about the size and the contrast of the objects to detect is ...
  • Coagulation time detection by means of a real-time image processing 

    Gasull Llampallas, Antoni; Vallverdú Bayés, Francesc; Marqués Acosta, Fernando (. IEEE, 1992)
    Text en actes de congrés
    Accés obert
    Several techniques for semi-automatic or automatic detection of coagulation time in blood or in plasma analysis are available in the literature. However, these techniques are either complex and demand for specialized ...
  • Hierarchical object detection with deep reinforcement learning 

    Bellver, Míriam; Giró Nieto, Xavier; Marqués Acosta, Fernando; Torres, Jordi (2016)
    Comunicació de congrés
    Accés obert
    We present a method for performing hierarchical object detection in images guided by a deep reinforcement learning agent. The key idea is to focus on those parts of the image that contain richer information and zoom on ...
  • Is a “happy dog” more “happy” than “dog”? - Adjective and Noun Contributions for Adjective-Noun Pair prediction 

    Fernàndez, Dèlia; Campos Camúñez, Victor; Jou, Brendan; Giró Nieto, Xavier; Chang, Shih-Fu (2016)

  • Hierarchical visual description schemes for still images and video sequences 

    Salembier Clairon, Philippe Jean; O'Connor, N; Correia Fernandez-Pereira, Paulo; Pereira, F (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    This paper proposes two description schemes (DSs) to describe the visual information of an audio-visual (AV) document. The first one, is devoted to still images. It describes the image visual appearance and its structure ...
  • Optimum watermark detection in color images 

    Sayrol Clols, Elisa; Vidal Manzano, José; Cabanillas, Silvia; Santamaria, Sonia (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    This work concentrates on the problem of watermarking embedding and optimum detection in color images through the use of spread spectrum techniques both in space (Direct Sequence Spread Spectrum or DSSS) and frequency ...
  • Human face segmentation and tracking using connected components and partition projection 

    Marqués Acosta, Fernando; Vilaplana Besler, Verónica; Buxes, A (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    A new technique for segmenting and tracking human faces in video sequences is presented. The algorithm uses a connected operator to extract the connected component that more likely belongs to a face. Such a connected ...
  • Accurate and automatic NOAA-AVHRR image navigation using a global contour matching approach 

    Eugenio, F; Marqués Acosta, Fernando; Gómez, L; Suarez, E; Rovaris, E (2000)
    Text en actes de congrés
    Accés obert
    The problem of precise and automatic AVHRR image navigation is tractable in theory, but has proved to be somewhat difficult in practice. The authors' work has been motivated by the need for a fully automatic and operational ...
