    • Multi-resolution Morphological Representation of Terrains 

      Danovaro, E.; Floriani, L. De; Vitali, M.; Papaleo, L. (The Eurographics Association, 2006)
      Mesh-based terrain representations provide accurate descriptions of a terrain, but fail in capturing its morphological structure. The morphology of a terrain is defined by its critical points and by the critical lines ...

    • A Natural and Effective Calibration of the CyberGlove 

      Partipilo, S.; Felice, F. De; Renna, F.; Attolico, G.; Distante, A. (The Eurographics Association, 2006)
      This work addresses the calibration of the CyberGlove, a device which provides information about the position and attitude in space of all the components of the user hand in a haptic system for the fruition of digital 3D ...

    • A New Descreening Technique in the Frequency Domain 

      Battiato, S.; Stanco, F. (The Eurographics Association, 2006)
      In this paper a new algorithm to obtain a continuous tone image starting from a halftoned one is proposed. This descreening technique is based on Butterworth filtering in the frequency domain. It removes the pattern of the ...

    • Preparation of Finite Element Models: The Use of an a Posteriori Mechanical Criterion 

      Ferrandes, R.; Marin, P. M.; Léon, J-C.; Giannini, F. (The Eurographics Association, 2006)
      A geometrical model needs to be simplified to perform a FE (Finite Element) analysis. Several tasks of shape processing are required during the FE model preparation phase. An appropriate geometric model and a suitable set ...

    • Real-time Cataract Surgery Simulation for Training 

      Agus, M.; Gobbetti, E.; Pintore, G.; Zanetti, G.; Zorcolo, A. (The Eurographics Association, 2006)
      Cataract is a clouding of the eye's natural lens, normally due to natural aging changes, and involving at least half of the population over 65 years. Cataract extraction is the only solution for restoring a clear vision, ...
