    • Ramses: a Visual Steganographic System 

      Battiato, S.; Blasi, G. Di; Gallo, G.; Patti, S. (The Eurographics Association, 2007)
      Steganography is the art of "secret communication". Its goal is to transmit a message (information) hidden inside another visible message. The typical visible message used in many steganographic systems is a digital image ...

    • Real Positioning in Virtual Environments Using Game Engines 

      Chiara, Rosario De; Santo, Valentina Di; Erra, Ugo; Scarano, Vittorio (The Eurographics Association, 2007)
      Immersive virtual environments offer a natural setting for educational and instructive experiences for users, and game engine technology offers an interesting, cost-effective and efficient solution for building them. In ...

    • Realtime Wavelet Video Encoding with Generic Graphics Processing Unit 

      Stocklöw, Carsten; Noll, Stefan (The Eurographics Association, 2007)
      Wavelet video encoding with multi-resolution analysis is the base for a layered coding scheme. From one video source streams of different resolutions can be generated in one coding process. To reduce computing time the ...

    • Rendering Order Optimization for SVGStat Improvement 

      Battiato, Sebastiano; Puglisi, Giovanni (The Eurographics Association, 2007)
      Vector representation of digital images offers a number of advantages over the more common raster representation, such as scalability and resolution independence. Many efforts have been made to deploy scalable raster ...

    • Rewriting Rules for the Dual Graph of a Stripified CLOD Mesh 

      Porcu, Massimiliano B.; Scateni, Riccardo (The Eurographics Association, 2007)
      A triangular mesh is the piecewise linear approximation of a sampled or analytical surface, when each patch is a triangle. The connectivity of the mesh can be easily represented using its dual graph. Each node of such a ...

    • Spline-based Shape Modeling by 3D Sketching 

      Han, Li; Amicis, Raffaele De; Conti, Giuseppe (The Eurographics Association, 2007)
      The increasing domination of spline-based graphic objects in CAD/CAS has driven a great attention to methods focusing on natural and intelligent free-form shape manipulation. We present a novel sketch-based system for the ...

    • Techniques for Computer Assisted Surgery 

      Turini, G.; Pietroni, N.; Ganovelli, F.; Scopigno, R. (The Eurographics Association, 2007)
      In the recent decades robotic and computer science have been gaining more and more relevance in all aspects of our lives. In surgery, for example, they gave birth to procedures that would be impossible to perform otherwise ...

    • Use of a 3D Graphical User Interface in Microelectronics Learning and Simulation of an Industrial Application 

      Bilotta, E.; Pantano, P.; Rinaudo, S.; Servidio, R.; Talarico, V. (The Eurographics Association, 2007)
      The COMSON project (COupled Multiscale Simulation and Optimization in Nanoelectronics) is a Marie Curie Research Training Network (RTN) supported by the European Commission within the 6th Framework Research Programme of ...

    • VR Studio: Solid Modelling in a Virtual Reality Environment 

      Cappello, F.; Ingrassia, T.; Romano, M. (The Eurographics Association, 2007)
      Today one of the most important industrial needs is to improve the design process, making it faster and more robust; of course such a requirement can be obtained by using virtual reality. In the field of mechanical design, ...
