    • Bandwidth reduction for remote navigation systems through view prediction and progressive transmission 

      Vázquez Alcocer, Pere Pau; Sbert Cassasayas, Mateu (Elsevier Science Direct, 2004)
      Article
      Accés restringit per política de l'editorial
      Remote navigation systems, such as exploration of virtual 3D worlds or remote surgery, usually require higher bandwidth than the Internet connection commonly available at home. In this paper,we explore a set of techniques ...

    • Bandwidth reduction techniques for remote navigation systems 

      Vázquez Alcocer, Pere Pau; Sbert Cassasayas, Mateu (2002)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper we explore a set of techniques to reduce the bandwidth in remote navigation systems. These systems, such as exploration of virtual 3D worlds or remote surgery, usually require higher bandwidth than the common ...

    • Fast adaptive selection of best views 

      Vázquez Alcocer, Pere Pau; Sbert Cassasayas, Mateu (2003)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Automatic computation of best views of objects is very useful. For example, they can be used as the starting point of a scene exploration, or to enrich galleries of objects available through Internet by adding an image a ...

    • Image-based modeling using viewpoint entropy 

      Vázquez Alcocer, Pere Pau; Feixas, Miquel; Sbert Cassasayas, Mateu; Heidrich, Wolfgang (2002)
      Text en actes de congrés
      Accés obert
      We present a new method to automatically determine the correct camera placement positions in order to obtain a minimal set of views for Image-Based Rendering. The viewpoints should cover all visible polygons with an adequate ...

    • On the fly best view detection using graphics hardware 

      Vázquez Alcocer, Pere Pau; Sbert Cassasayas, Mateu (2004)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Selection of good camera positions has many applications in Computer Graphics. It can be used to compute a walkthrough inside a scene that shows a higher amount of information or to select a minimal set of views for ...

    • Perception-based illumination information measurement and light source placement 

      Vázquez Alcocer, Pere Pau; Sbert Cassasayas, Mateu (2003)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The automatic selection of good viewing parameters is very complex. In most cases, the notion of good strongly depends on the concrete application. Moreover, when an intuitive definition of good view is available, it is ...

    • Point-based modeling from a single image 

      Vázquez Alcocer, Pere Pau; Marco Gómez, Jordi; Sbert Cassasayas, Mateu (2004)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The complexity of virtual environments has grown spectacularly over the recent years, mainly thanks to the use of the currently cheap high performance graphics cards. As the graphics cards improve the performance and the ...

    • Viewpoint selection using viewpoint entropy 

      Vázquez Alcocer, Pere Pau; Feixas, Miquel; Sbert Cassasayas, Mateu; Heidrich, Wolfgang (2001)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Computation of good viewpoints is important in several fields: computational geometry, visual servoing, robot motion, graph drawing, etc. In addition, selection of good views is rapidly becoming a key issue in computer ...
