• openAccess   Information theory tools for viewpoint selection, mesh saliency and geometry simplification 

      Sbert Casasayas, Mateu; Feixas, Miguel; Castelló Boscá, Pascual; Chover, Miguel Springer (2009)
      In this chapter we review the use of an information channel as a unified framework for viewpoint selection, mesh saliency and geometry simplification. Taking the viewpoint distribution as input and object mesh polygons as ...
    • closedAccess   Reducing complexity in polygonal meshes with view-based saliency 

      Castelló Boscá, Pascual; Chover, Miguel; Sbert Casasayas, Mateu; Feixas, Miguel Elsevier (2014-08)
      Salient features in 3D meshes such as small high-curvature details in the middle of largely flat regions are easily ignored by most mesh simplification methods. Nevertheless, these features can be perceived by human observers ...
    • closedAccess   Simplification method for textured polygonal meshes based on structural appearance 

      González Ballester, Carlos; Castelló Boscá, Pascual; Chover, Miguel; Sbert Casasayas, Mateu; Feixas, Miguel; Gumbau Portalés, Jesús Springer-Verlag (2013-05)
      This paper proposes an image-based simplification method for textured triangle meshes that preserves the structural appearance of textured models. Models used in interactive applications are usually composed of textured ...
    • openAccess   Tsallis entropy for geometry simplification 

      Castelló Boscá, Pascual; González, Carlos; Sbert Casasayas, Mateu; Feixas, Miguel; Chover, Miguel MDPI Publishing (2011-09-29)
      This paper presents a study and a comparison of the use of different information-theoretic measures for polygonal mesh simplification. Generalized measures from Information Theory such as Havrda–Charva ́t–Tsallis entropy ...
    • closedAccess   Viewpoint-based simplification using f-divergences 

      Castelló Boscá, Pascual; Sbert Casasayas, Mateu; Chover, Miguel; Feixas, Miguel Elsevier (2008)
      We propose a new viewpoint-based simplification method for polygonal meshes, driven by several f-divergences such as Kullback-Leibler, Hellinger and Chi-Square. These distances are a measure of discrimination between ...
    • closedAccess   Viewpoint-driven simplification using mutual information 

      Castelló Boscá, Pascual; Sbert Casasayas, Mateu; Chover, Miguel; Feixas, Miguel Elsevier (2008)
      In this paper, a new viewpoint-based simplification approach is proposed for polygonal meshes. This approach is driven by an information-theoretic measure, viewpoint mutual information. Our algorithm applies the best ...
