      Murch, Gerald M. (The Eurographics Association, 1982)
      Measurements of a display user s lens accommodation and binocular convergence were used to assess the visual impact of display color, display technology, display work time, and display contrast. The studies reported here ...
    • Measuring an Illusion:The Influence of System Performance on Size Perception in Virtual Environments

      The effects of system performance variations on people s estimation of virtual object sizes in a multi-sided back projection virtual reality system have been explored. Seventy-seven participants adjusted the sizes of three ...
    • Measuring and Enhancing the Legibility of GPU-rendered Text 

      Tycowicz, Christoph von; Loviscach, Joern (The Eurographics Association, 2008)
      Whereas the rendering of tiny typefaces in 2D applications has been perfected over decades, the legibility of text in 3D visualizations has rarely been addressed. This affects road signs, meters, screens, and books in ...
    • Measuring and Rendering Art Paintings Using an RGB Camera 

      Tominaga, Shoji; Tanaka, Norihiro (Eurographics Association, 2002)
      A method is proposed for measuring and rendering of art paints by using the simple system of an RGB camera only. The surface shape of an art painting is considered as a rough plane rather than a three-dimensional curved ...
    • Measuring BRDFs of Immersed Materials 

      Berger, Kai; Reshetouski, Ilya; Magnor, Marcus; Ihrke, Ivo (The Eurographics Association, 2011)
      We investigate the effect of immersing real-world materials into media of different refractive indices. We show, that only some materials follow the Fresnel-governed behaviour. In reality, many materials exhibit unexpected ...
    • Measuring Changes in Cultural Heritage Objects with Reflectance Transform Imaging 

      Manfredi, Marcello; Williamson, Greg; Kronkright, Dale; Doehne, Eric; Bearman, Gregory; Jacobs, Megan; Marengo, Emilio (The Eurographics Association, 2013)
      Sites and objects of cultural heritage from art to ancient inscriptions to ruins are under constant attack by time and the environment. While much is known about how material components change from laboratory-based ...
    • Measuring Complexity in Lagrangian and Eulerian Flow Descriptions 

      Jaenicke, H.; Scheuermann, G. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Automatic detection of relevant structures in scientific data sets is still one of the big challenges in visualization. Techniques based on information theory have shown to be a promising direction to automatically highlight ...
    • Measuring Difficulty in Platform Videogames 

      Mourato, Fausto José; Santos, Manuel Próspero dos (The Eurographics Association, 2021)
      Automatic generation of game levels improves replayability and also allows content adaptation. One important aspect to take into account in the creation of any videogame is difficulty, in particular when it is possible to ...
    • Measuring Privacy and Utility in Privacy-Preserving Visualization 

      Dasgupta, Aritra; Chen, Min; Kosara, Robert (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In previous work, we proposed a technique for preserving the privacy of quasi-identifiers in sensitive data when visualized using parallel coordinates. This paper builds on that work by introducing a number of metrics that ...
    • Measuring Realism in Hair Rendering 

      Ramesh, Girish; Turner, Martin J. (The Eurographics Association, 2013)
      Visualisation of hair is an extremely complex problem within the field of Computer Graphics. Over the last 10 years, huge strides have been made in the area of physically-based hair rendering, giving rise to many applications ...
    • Measuring Symmetry in Drawings of Graphs 

      Welch, Eric; Kobourov, Stephen (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Layout symmetry is an important and desired feature in graph drawing. While there is a substantial body of work in computer vision around the detection and measurement of symmetry in images, there has been little effort ...
    • Measuring the Discernability of Virtual Objects in Conventional and Stylized Augmented Reality 

      Fischer, Jan; Cunningham, Douglas; Bartz, Dirk; Wallraven, Christian; Bülthoff, Heinrich; Straßer, Wolfgang (The Eurographics Association, 2006)
      In augmented reality, virtual graphical objects are overlaid over the real environment of the observer. Conventional augmented reality systems normally use standard real-time rendering methods for generating the graphical ...
    • Measuring the Perception of Visual Realism in Images 

      Rademacher, Paul; Lengyel, Jed; Cutrell, Edward; Whitted, Turner (The Eurographics Association, 2001)
      One of the main goals in realistic rendering is to generate images that are indistinguishable from photographs but how do observers decide whether an image is photographic or computer-generated? If this perceptual process ...
