    • Studying the Fidelity Requirements for a Virtual Ballet Dancer 

      Neagle, R.J.; Ng, K.; Ruddle, R.A. (The Eurographics Association, 2003)
      Teaching dance, especially ballet, usually involves the phrase: 'watch, copy and learn' and improvement is made by emulation. This involves not only how to achieve the steps but also the quality of the movement. In this ...

    • Lambertian Correction for Rough and Specular Surfaces 

      Robles-Kelly, A.; Hancock, E.R. (The Eurographics Association, 2003)
      This paper describes a method for performing Lambertian reflectance for rough and specular surfaces. Rather than using an existing reflectance model, we present a method for estimating the reflectance function from image ...

    • Iterative Multi-Planar Camera Calibration: Improving Stability using Model Selection 

      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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • User Interfaces for Mobile Augmented Reality Systems 

      Feiner, Steve (The Eurographics Association, 2003)
      What should user interfaces look like when they become an integral part of how we experience the world around us? This talk provides an overview of work that explores user interface design issues for mobile augmented reality ...

    • A Vision-Based Location System using Fiducials 

      Johnston, D.J.; Clark, A.F. (The Eurographics Association, 2003)
      A system for vision-based ego location using 'targets' or 'fiducials' is described. The system is robust and operates on commodity hardware in real time. The accuracy of the system is assessed and found to be good enough ...

    • Visualising Video Sequences using Direct Volume Rendering 

      Daniel, G.; Chen, M. (The Eurographics Association, 2003)
      It is evident that more and more video data is being generated everyday, for example, by TV broadcast companies and security cameras. However, whilst we are overwhelmed by the huge amount of imagery data, machine vision ...

    • Cartoon-Style Rendering of Motion from Video 

      Collomosse, J.P.; Hall, P.M. (The Eurographics Association, 2003)
      The contribution of this paper is a novel non-photorealistic rendering (NPR) system capable of rendering motion within a video sequence in artistic styles. A variety of cartoon-style motion cues may be inserted into a video ...

    • Quasi-3D cell-based Animation 

      Qi, M.; Willis, P.J. (The Eurographics Association, 2003)
      We present a method for image compositing and rendering using 2D geometric shapes or raster images as input primitives, disposed in a 3D environment around which the camera can move. An animation system has been implemented ...

    • Investigating Occlusion and Discretization Problems in Image-Based Blurring Techniques 

      Barsky, Brian (The Eurographics Association, 2003)
      Traditional computer graphics methods render images that appear sharp at all depths. Adding blur can add realism to a scene, provide a sense of scale, and draw a viewer's attention to a particular region of a scene. Our ...

    • Prometheus: Facial Modelling, Tracking and Puppetry 

      Thorne, J.M.; Chatting, D.J. (The Eurographics Association, 2003)
      The Prometheus project sought to create a real-time production chain for 3D content. This paper summarises the techniques that were developed for facial modelling, tracking and puppetry. The process used for creating ...

    • Coding 3D Facial Models forMugshot Applications 

      Hyde, J.; Robinson, J. (The Eurographics Association, 2003)
      Three-dimensional information about a human face may have some correlation with the colour information present in its flat texture image. In order to maximise the available information for human identification of faces, a ...

    • 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 ...

    • 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 ...

    • Real-Time Capture, Reconstruction and Insertion into Virtual World of Human Actors 

      Hasenfratz, J.M.; Lapierre, M.; Gascuel, J.-D.; Boyer, E. (The Eurographics Association, 2003)
      In this paper, we show how to capture an actor with no intrusive trackers and without any special environment like blue set, how to estimate its 3D-geometry and how to insert this geometry into a virtual world in real-time. ...

    • On the Editing of Images: Selecting, Cutting and Filling-in 

      Labrosse, F. (The Eurographics Association, 2003)
      This paper is two-fold. On the one hand, we present a system using qualitative spatial reasoning to help a user choose parts of an image that form interesting objects. The system then allows the user to cut these parts as ...
