    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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. ...

    • 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 ...

    • An Adaptive Sampling Approach to Incompressible Particle-Based Fluid 

      Hong, Woosuck; House, Donald H.; Keyser, John (The Eurographics Association, 2009)
      We describe an adaptive particle-based technique for simulating incompressible fluid that uses an octree structure to compute inter-particle interactions and to compute the pressure field. Our method extends the hybrid ...

    • An Edge-based Approach to Adaptively Refining a Mesh for Cloth Deformation 

      Simnett, Timothy J. R.; Laycock, Stephen D.; Day, Andy M. (The Eurographics Association, 2009)
      Simulating cloth in real-time is a challenging endeavour due to the number of triangles necessary to depict the potentially frequent changes in curvature, in combination with the physics calculations which model the ...

    • 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 ...

    • Simulation of X-ray Attenuation on the GPU 

      Vidal, Franck; Garnier, Manuel; Freud, Nicolas; Létang, Jean Michel; John, Nigel W. (The Eurographics Association, 2009)
      In this paper, we propose to take advantage of computer graphics hardware to achieve an accelerated simulation of X-ray transmission imaging, and we compare results with a fast and robust software-only implementation. The ...
