  • Diffusion and Fractional Diffusion Based Image Processing 

    Blackledge, Jonathan Michael (The Eurographics Association, 2009)
    We consider the background to describing strong scattering in terms of diffusive processes based on the diffusion equation. Intermediate strength scattering is then considered in terms of a fractional diffusion equation ...
  • Calibrating a COTS Monitor to DICOM Standard 

    Grimstead, Ian J.; Avis, Nick J. (The Eurographics Association, 2009)
    Abstract We present a method for calibrating a commodity, off-the-shelf (COTS) monitor (costing in the region of £200) to produce a greyscale image approximately calibrated to the DICOM standard, rather than require a ...
  • Discrete Element Modelling Using a Parallelised Physics Engine 

    Longshaw, Stephen M.; Turner, Martin J.; Finch, Emma; Gawthorpe, Robert (The Eurographics Association, 2009)
    Discrete Element Modelling (DEM) is a technique used widely throughout science and engineering. It offers a convenient method with which to numerically simulate a system prone to developing discontinuities within its ...
  • Coastal Shelf Visualization using VTK and OpenDX of Hydro-Informatic Numerical Models 

    George, Richard L. S. F.; Roberts, Jonathan C. (The Eurographics Association, 2009)
    Scientific visualization has an important role in climate change analysis, especially by creating dynamic interactive environments. The earth sciences, such as oceanography, utilize many numerical models; experts wish to ...
  • Real-time Rendering of Deformable Translucent Objects 

    Benmounah, Nadir; Jolivet, Vincent; Ghazanfarpour, Djamchid (The Eurographics Association, 2009)
    This paper introduces an efficient real-time shading model to simulate light transport in translucent materials. In this work no pre-processing step is needed, allowing us to deform translucent objects at interactive rates. ...
  • Uncertain Flow Visualization using LIC 

    Osorio, Rodolfo S. Allendes; Brodlie, Ken W. (The Eurographics Association, 2009)
    In this paper we look at the Line Integral Convolution method for flow visualization and ways in which this can be applied to the visualization of two dimensional, steady flow fields in the presence of uncertainty. To ...
  • Towards Object Recognition using HDR Video, Stereoscopic Depth Information and SIFT 

    May, Michael; Morris, Tim; Markham, Keith; Crowther, William J.; Turner, Martin J. (The Eurographics Association, 2009)
    In this paper we propose a framework that will recognise objects from a moving platform using scale invariant features, high dynamic range (HDR) video and stereoscopic depth information. The paper focuses on initial work ...
  • Aesthetic-Interaction: Exploring the Importance of the Visual Aesthetic in the Creation of Engaging Photorealistic VR Environments 

    Carroll, Fiona (The Eurographics Association, 2009)
    Nearly forty years since its conception, the medium of VR is still an enigma. In many ways, it is a medium that still lacks its own uniform language. VR, and particularly photorealistic VR, is a medium that is so occupied ...
  • Near-correct Ocular Accommodation Responses to a 3d Display, Using Multiple Image Planes and Depth Filtering 

    MacKenzie, Kevin J.; Watt, Simon J. (The Eurographics Association, 2009)
    Conventional stereo displays provide incorrect focus cues because the image is presented on a single surface. This is known to cause a number of aversive symptoms in users, including fatigue and discomfort. Multiple-focal-plane ...
  • Influencing User Attention Using Real-Time Stylised Rendering 

    Redmond, Niall; Dingliana, John (The Eurographics Association, 2009)
    In this paper, we present a series of experiments that were conducted to further understand how using adaptive levels of artistic abstraction within an interactive 3D scene can influence user gaze behaviour. We found that ...
  • Touching The Invisible - Molecular Haptics 

    Davies, R. Andrew; Maskery, James S.; John, Nigel W. (The Eurographics Association, 2009)
    Novel, simple, cost-effective applications combining haptics and computer graphics for the study of key chemical concepts such as reactivity and periodicity at AS/A-level and undergraduate level are described.
  • Developing an Application to Provide Interactive Threedimensional Visualisation of Bone Fractures 

    Wilson, Arline F.; Musgrove, Peter B.; Buckley, Kevan A.; Pearce, Gill; Geoghegan, John (The Eurographics Association, 2009)
    The main research question for this work is: What are the factors involved in developing a three-dimensional (3D) interactive model of a bone fracture and how best may these be addressed? This paper presents work in progress ...
  • Higher Dimensional Vector Field Visualization: A Survey 

    Peng, Zhenmin; Laramee, Robert S. (The Eurographics Association, 2009)
    Vector field visualization research has evolved very rapidly over the last two decades. There is growing consensus amongst the research community that the challenge of two-dimensional vector field visualization is virtually ...
  • Fast and Accurate Finite Element Method for Deformation Animations 

    Tang, Wen; Wan, Tao Ruan; Niquin, Ceddric; Schildknecht, Alexandre (The Eurographics Association, 2009)
    We present a matrix clustering method for speeding up finite element computations for non-rigid object animation. The method increases the efficiency of computing deformation dynamics through a compression scheme that ...
  • Markerless Visual Human Movement Tracking for HCI: What Frequency? 

    Kahlesz, Ferenc; Klein, Reinhard (The Eurographics Association, 2009)
    This paper tries to establish a minimal tracking frequency limit for visual human movement tracking algorithms that intend to be useful for the realization of some kind Human-Computer-Interaction (HCI) metaphor. More ...
  • Hardware Accelerated Shaders Using FPGAs 

    Goddard, Luke; Stephenson, Ian (The Eurographics Association, 2009)
    We demonstrate that Field Programable Gate Arrays (FPGAs) can be used to accelerate shading of surfaces for production quality rendering (a task standard interactive graphics hardware is generally ill-suited to) by allowing ...
  • Facial Expression Transferring with a Deformable Model 

    Xiang, Guofu; Ju, Xiangyang; Holt, Patrik O'B.; Shang, Lin (The Eurographics Association, 2009)
    This paper presents an automated approach to transferring facial expressions from a generic facial model onto various individual facial models without requiring any prior correspondences and manual interventions during the ...
  • Design and Evaluation of a Hardware Accelerated Ray Tracing Data Structure 

    Steffen, Michael; Zambreno, Joseph (The Eurographics Association, 2009)
    The increase in graphics card performance and processor core count has allowed significant performance accel- eration for ray tracing applications. Future graphics architectures are expected to continue increasing the ...
  • A Framework for Physically Based Forest Fire Animation 

    Gundersen, Odd Erik; Skjermo, Jo (The Eurographics Association, 2009)
    Abstract In this paper, we propose a conceptual framework for animating physically based forest fires. Animating forest fire is a computationally demanding task as trees are intricate structures and fire is a highly complex ...
  • An Aliasing Theory of Shadow Mapping 

    Zhang, Fan; Zhao, Chong; Sun, Hanqiu (The Eurographics Association, 2009)
    Shadow mapping is a popular image-based technique for real-time shadow rendering. Although numerous improvements have been made to help anti-aliasing in shadow mapping, there is a lack of mathematical tools that allow us ...
