    • Manipulating Topological Decompositions of Non-Manifold Shapes 

      Canino, David (The Eurographics Association, 2016)
      Decomposing a non-manifold shape into its almost manifold components is a powerful tool for analyzing its complex structure. Many techniques for decomposing a non-manifold shape are available in the current literature, and ...
    • Persistent Homology: a Step-by-step Introduction for Newcomers 

      Fugacci, Ulderico; Scaramuccia, Sara; Iuricich, Federico; Floriani, Leila De (The Eurographics Association, 2016)
      Persistent homology is a powerful notion rooted in topological data analysis which allows for retrieving the essential topological features of an object. The attention on persistent homology is constantly growing in a large ...
    • Practical Free-form RTI Acquisition with Local Spot Lights 

      Pintus, Ruggero; Ciortan, Irina Mihaela; Giachetti, Andrea; Gobbetti, Enrico (The Eurographics Association, 2016)
      We present an automated light calibration pipeline for free-form acquisition of shape and reflectance of objects using common off-the-shelf illuminators, such as LED lights, that can be placed arbitrarily close to the ...
    • Practical Offline Rendering of Woven Cloth 

      Nelson, Vidar; McEvoy, Peter M.; Fratarcangeli, Marco (The Eurographics Association, 2016)
      The techniques for rendering woven cloth employed in a production environment often neglect many of the structural features of the fabric, as well as light-scattering processes that occur in the yarn. Research in this area ...
    • Retinal Image Analysis with Shearlets 

      Levet, Francesco; Duval-Poo, Miguel A.; Vito, Ernesto De; Odone, Francesca (The Eurographics Association, 2016)
      In this paper we propose a method for segmenting blood vessels in retinal images based on the shearlet transform. Shearlets are a relatively new directional multi-scale framework for signal analysis, which have been shown ...
    • Selective Rasterized Ray-traced Reflections on the GPU 

      Kastrati, Mattias Frid; Goswami, Prashant (The Eurographics Association, 2016)
      Ray-tracing achieves impressive effects such as realistic reflections on complex surfaces but is also more computationally expensive than classic rasterization. Rasterized ray-tracing methods can accelerate ray-tracing by ...
    • STAG 2016: Frontmatter 

      Gianni Pintore; Filippo Stanco (Eurographics Association, 2016)
    • Surface Reconstruction from Range Images 

      Mariosa, Gianfranco; Fioraio, Nicola; Franchi, Alessandro; Stefano, Luigi Di (The Eurographics Association, 2016)
      In this work we propose an algorithm for fast and detailed surface reconstruction from range images. Our method extends the well-known Ball Pivoting Algorithm (BPA) so to exploit the inherent structure of range images, ...
    • Tonal Art Maps with Image Space Strokes 

      Szécsi, László; Szirányi, Marcell; Kacsó, Ágota (The Eurographics Association, 2016)
      This paper presents a hybrid hatching solution that uses robust and fast texture space hatching to gather stroke fragments, but fits stylized brush strokes over those fragments in image space. Thus we obtain a real-time ...
    • Tracking the Evolution of Rainfall Precipitation Fields Using Persistent Maxima 

      Biasotti, Silvia; Cerri, Andrea; Pittaluga, Simone; Sobrero, Davide; Spagnuolo, Michela (The Eurographics Association, 2016)
      In this paper we propose a novel methodology for tracking the maxima of rainfall precipitation fields, whose changes in time may give interesting insights on the evolution of storm. Our approach is based on a topological ...
    • Vocal One Switch (VOS) Selection Interfaces for Virtual and Augmented Reality Hands-free Tasks 

      Manuri, Federico; Sanna, Andrea; Lamberti, Fabrizio; Paravati, Gianluca (The Eurographics Association, 2016)
      Several virtual and augmented reality tasks involve users in hands-free interactions; in this case, speech-based systems are often preferred for their intuitiveness and naturalness. On the other hand, the robustness of ...
