      Vigueras, J.F.; Berger, M.-O.; Simon, G. (The Eurographics Association, 2003)
      Tracking, or camera pose determination, is the main technical challenge in numerous applications in computer vision and especially in Augmented Reality. However, pose computation processes commonly exhibit some fluctuations ...
    • Real-Time Per-pixel Rendering of Bump-mapped Textures Captured using Photometric Stereo 

      Robb, M.; Spence, A.D.; Chantler, M.J.; Timmins, M. (The Eurographics Association, 2003)
      We present recent results from an EPSRC funded project VirTex (Virtual Textile Catalogues). The goal of this project is to develop graphics and image-processing software for the capture, storage, search, retrieval and ...
    • Interpretation of Fuzzy Logic For Texture Queries in CBIR 

      Kulkarni, S. (The Eurographics Association, 2003)
      This paper presents a novel fuzzy logic based approach for the interpretation of texture queries. Tamura feature extraction technique is used to extract each texture feature of an image in the database. A term set on each ...
    • Collaborative Vision and Interactive Mosaicing 

      Robinson, J.A. (The Eurographics Association, 2003)
      I propose criteria for collaborative vision applications where a camera user/operator and a computer work together to analyse a scene. An example of how these may be fulfilled is provided in IMP - an interactive mosaicing ...
    • Applications of Clifford Algebra in Mixed Reality Environment 

      Ho, E.Y.T. (The Eurographics Association, 2003)
      The 'beauty' of Clifford's Geometric Algebras is its ability to incorporate other algebras and it is the 'mother' algebra for all algebras. This paper introduces the advantage of using this algebra by combining and augmenting ...
    • Models from Image Triplets using Epipolar Gradient Features 

      Vincent, É.; Laganière, R. (The Eurographics Association, 2003)
      In an application where sparse matching of feature points is used towards fast scene reconstruction, the choice of the type of features to be matched has an important impact on the quality of the resulting model. In this ...
    • An Occlusion Culling Toolkit for OpenSG PLUS 

      Staneker, Dirk (The Eurographics Association, 2003)
      Image-space occlusion culling is an useful approach to reduce the rendering load of large polygonal models in scienti c computing, mechanical engineering, or virtual medicine. Like most large model techniques, occlusion ...
    • A Flexible and Versatile Studio for Synchronized Multi-View Video Recording 

      Theobalt, C.; Li, M.; Magnor, M.A.; Seidel, H.-P. (The Eurographics Association, 2003)
      In recent years, the convergence of computer vision and computer graphics has put forth new research areas that work on scene reconstruction from and analysis of multi-view video footage. In free-viewpoint video, for ...
    • A Region Adjacency Tree Approach to the Detection and Design of Fiducials 

      Costanza, E.; Robinson, J. (The Eurographics Association, 2003)
      We report a topological approach to fiducial recognition for real-time applications. Independence from geometry makes the system tolerant to severe distortion, and allows encoding of extra information. The method is based ...
    • Table of Contents and Preface 

      Peter Hall and Philip Willis (The Eurographics Association, 2003)
    • Frontiers in 3D Photography: Reflectance and Motion 

      Seitz, Steve (The Eurographics Association, 2003)
      The last decade has seen great progress in 3D shape capture technology, both in terms of research ad- vances and successful commercial systems. So why don't most people own 3D cameras? Aside from such issues as expense and ...
    • Digitisation to Presentation- BuildingVirtual Museum Exhibitions 

      Patel, M.; White, M.; Walczak, K.; Sayd, P. (The Eurographics Association, 2003)
      We describe an innovative system designed for museums to create, manage and present multimedia based representations of museum artefacts in virtual exhibitions both inside and outside museums. Our system creates digital ...
    • Use and Re-use of Facial Motion CaptureData 

      Lorenzo, M.S.; Edge, J.D.; King, S.A.; Maddock, S. (The Eurographics Association, 2003)
      Motion capture (mocap) data is commonly used to recreate complex human motions in computer graphics. Markers are placed on an actor, and the captured movement of these markers allows us to animate computer-generated ...
    • Parallel Stereo Visualization For ClustersWith OpenInventor: A Case Study For The Automotive Industry 

      Vega, Fernando; Suÿner, Gerd; Reuding, Thomas; Greiner, Günther (The Eurographics Association, 2003)
      Stereo visualization is an area which can greatly benefit from cluster computing due to the parallelizable nature of the rendering task. In order to implement this idea, we have developed a novel software architecture which ...
    • Enhanced Texture Editing using Self Similarity 

      Brooks, S.; Cardle, M.; Dodgson, N.A. (The Eurographics Association, 2003)
      Texture mapping is an indispensable tool for achieving realism in computer graphics. Significant progress has been made in recent years with regards to the synthesis and editing of 2D texture images. However, the exploration ...
