    • A Validation Tool For Improving Semantic Segmentation of Complex Natural Structures 

      Pavoni, Gaia; Corsini, Massimiliano; Palma, Marco; Scopigno, Roberto (The Eurographics Association, 2019)
      The automatic recognition of natural structures is a challenging task in the supervised learning field. Complex morphologies are difficult to detect both from the networks, that may suffer from generalization issues, and ...

    • Validity Issues for Modular Boundary Models 

      Bruzzone, Elisabetta; De Floriani, Leila (Eurographics Association, 1991)
      Modular boundary models are a class of solid models which describe a solid object as a collection of face-abutting object parts, called components. The Face-to-Face Composition (FFC) model is a specific model of this class, ...

    • Variable k-buffer using Importance Maps 

      Vasilakis, Andreas-Alexandros; Vardis, Konstantinos; Papaioannou, Georgios; Moustakas, Konstantinos (The Eurographics Association, 2017)
      Successfully predicting visual attention can significantly improve many aspects of computer graphics and games. Despite the thorough investigation in this area, selective rendering has not addressed so far fragment visibility ...

    • Variable-Radius Blending by Using Gregory Patches in Geo- metric Modeling 

      Harada, T.; Konnoa, K.; Chiyokura, H. (Eurographics Association, 1991)
      Blending surfaces, which connect two curved surfaces smoothly, often appear in geometric modeling. Many of the blending surfaces are variable-radius blends. Variableradius blending surfaces are very important in the design ...

    • Variation-Factored Encoding of Facade Images 

      Alsisan, Suhib; Mitra, Niloy J. (The Eurographics Association, 2012)
      Urban facades contain large-scale repetitions in the form of windows, doors, etc. Such elements often are in different configurations (e.g., open or closed) obscuring their regular arrangements to any direct low-level pixel ...

    • Variational Design and Fairing of Spline Surfaces 

      Greiner, Gunther (Blackwell Science Ltd and the Eurographics Association, 1994)
      Variational principles have become quite popular in the design of free form surfaces. Among others they are used for fairing purposes. The choice of the right fairness functional is a crucial step. There is always a ...

    • Variational Surface Design and Surface Interrogation 

      Hagen, H.; Hahmann, St.; Bonneau, G.-P. (Blackwell Science Ltd and the Eurographics Association, 1993)
      The generation of technical smooth surfaces from a mesh of three-dimensional data points is an important problem in geometric modelling. In this publication we give a survey of some new techniques based on a calculus of ...

    • Variations on a Dither Algorithm 

      Pins, Markus; Hild, Hermann (Eurographics Association, 1989)
      Mapping continuous-tone pictures into digital halftone pictures, i.e. 0/1-pictures, for printing purposes is a well explored technique. In this paper, one of these algorithms, the two-dimensional error-diffusion algorithm ...

    • VBTC: GPU-Friendly Variable Block Size Texture Encoding 

      Krajcevski, Pavel; Golas, Abhinav; Ramani, Karthik; Shebanow, Michael; Manocha, Dinesh (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Recent advances in computer graphics have relied on high-quality textures in order to generate photorealistic real-time images. Texture compression standards meet these growing demands for data, but current texture compression ...

    • VDub: Modifying Face Video of Actors for Plausible Visual Alignment to a Dubbed Audio Track 

      Garrido, Pablo; Valgaerts, Levi; Sarmadi, Hamid; Steiner, Ingmar; Varanasi, Kiran; Perez, Patrick; Theobalt, Christian (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In many countries, foreign movies and TV productions are dubbed, i.e., the original voice of an actor is replaced with a translation that is spoken by a dubbing actor in the country's own language. Dubbing is a complex ...

    • Vector Field Based Texture Mapping of Animated Implicit Objects 

      Smets-Solanes, Jean-Paul (Blackwell Science Ltd and the Eurographics Association, 1996)
      This paper shows that an adequate use of vectorfields can solve most inconsistencies related to texture mapping that appear in current animation and rendering systems based on implicit objects. The method used is based on ...

    • Vector Fields: an Interactive Tool for Animation, Modeling and Simulation with Physically Based 3D Particle Systems and Soft Objects 

      Hilton, Travis L.; Egbert, Parris K. (Blackwell Science Ltd and the Eurographics Association, 1994)
      Vectorfields have traditionally been used in computer graphics as a means of visualizing models over time. This paper presents a system which extends the use of vector fields as an interactive tool for physically based ...

    • Vegetable Matter Decay: An Exceptional Student 'Innovations' Project 

      Anderson, Eike Falk; Cirdei, Bianca; Adzhiev, Valery (The Eurographics Association, 2019)

    • Velocity-Based LOD Reduction in Virtual Reality: A Psychophysical Approach 

      Petrescu, David; Warren, Paul A.; Montazeri, Zahra; Pettifer, Steve (The Eurographics Association, 2023)
      Virtual Reality headsets enable users to explore the environment by performing self-induced movements. The retinal velocity produced by such motion reduces the visual system's ability to resolve fine detail. We measured ...

    • VelvetPath - Layout Design System with Sketch and Paint Manipulations 

      Tobita, Hiroaki (Eurographics Association, 2003)
