    • Colour Processing in Adversarial Attacks on Face Liveness Systems 

      Abduh, Latifah; Ivrissimtzis, Ioannis (The Eurographics Association, 2019)
      In the context of face recognition systems, liveness test is a binary classification task aiming at distinguishing between input images that come from real people's faces and input images that come from photos or videos ...

    • Controlling 3D Visualisations with Multiple Degrees of Freedom 

      Sandoval, Mario; Morris, Tim; Turner, Martin (The Eurographics Association, 2019)
      In this paper, the two major components of a new multi-layer framework ideal for two-handed interaction in desktop virtual environments called Library for Interactive Settings of User-Mode (LISU) are explained. In addition, ...

    • Evaluating Models for Virtual Forestry Generation and Tree Placement in Games 

      Williams, Benjamin; Ritsos, Panagiotis; Headleand, Christopher (The Eurographics Association, 2019)
      A handful of approaches have been previously proposed to generate procedurally virtual forestry for virtual worlds and computer games, including plant growth models and point distribution methods. However, there has been ...

    • Fast and Efficient Nearest Neighbor Search for Particle Simulations 

      Gross, Julian; Köster, Marcel; Krüger, Antonio (The Eurographics Association, 2019)
      One of the fundamental algorithms in particle simulations is the identification and iteration over nearest neighbors of every particle. Well-known examples are SPH or PBD simulations that compute forces and particle-position ...

    • Hash-based Hierarchical Caching for Interactive Previews in Global Illumination Rendering 

      Roth, Thorsten; Weier, Martin; Bauszat, Pablo; Hinkenjann, André; Li, Yongmin (The Eurographics Association, 2019)
      Modern Monte-Carlo-based rendering systems still suffer from the computational complexity involved in the generation of noise-free images, making it challenging to synthesize interactive previews. We present a framework ...

    • Optimising Underwater Environments for Mobile VR 

      Cenydd, Llyr ap; Headleand, Christopher (The Eurographics Association, 2019)
      Mobile Virtual Reality (VR) has advanced considerably in the last few years, driven by advances in smartphone technology. There are now a number of commercial offerings available, from smartphone powered headsets to ...

    • Projectional Radiography Simulator: an Interactive Teaching Tool 

      Sujar, Aaron; Kelly, Graham; García, Marcos; Vidal, Franck (The Eurographics Association, 2019)
      Radiographers need to know a broad range of knowledge about X-ray radiography, which can be specific to each part of the body. Due to the harmfulness of the ionising radiation used, teaching and training using real patients ...

    • Recognising Human-Object Interactions Using Attention-based LSTMs 

      Almushyti, Muna; Li, Frederick W. B. (The Eurographics Association, 2019)
      Recognising Human-object interactions (HOIs) in videos is a challenge task especially when a human can interact with multiple objects. This paper attempts to solve the problem of HOIs by proposing a hierarchical framework ...

    • Robust and Flexible Puzzle Solving with Corner-based Cycle Consistent Correspondences 

      Wang, T.; Vladimirov, K.; Goh, S.; Lai, Y.-K.; Xie, X.; Tam, G. K. L. (The Eurographics Association, 2019)
      Solving jigsaw puzzles is a classic problem in computer vision with various applications. Over the past decades, many useful approaches have been introduced. Most existing works use edge-wise similarity measures for ...
