    • 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   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 ...
