    • Beyond Image Quality Comparison 

      Bornik, Alexander; Cech, Peter; Ferko, Andrej; Perko, Roland (Eurographics Association, 2003)
      We solve the problem of quantitative measuring of image quality, beyond the widely used MSE (mean square error) or even visual comparison. We combine eight feature-based and perceptually-oriented image quality metrics. The ...

    • Continuous Local Parameterization of Polygons 

      Maillot, Jerome (Eurographics Association, 2003)
      Texture mapping has now become a standard technique for adding visual details to 3d models. Nevertheless, intuitive mapping tools have made little progress in the past decade, compared to other computer graphics areas: ...

    • Crosstalk reduction in passive stereo-projection systems 

      Klimenko, Stanislav; Frolov, Pavel; Nikitina, Lialia; Nikitin, Igor (Eurographics Association, 2003)
      We describe a scheme for reduction of depolarization artefacts in passive stereo-projection systems. These problems appear due to non-perfectness of stereo-projection equipment: depolarization of the light due to reflection ...

    • Cyclification of Human Motion for Animation Synthesis 

      Ahmed, Amr; Mokhtarian, Farzin; Hilton, Adrian (Eurographics Association, 2003)
      In this paper, new techniques are introduced for matching cyclic motion boundaries by using simple animation processing algorithms based on some observed characteristics from different families of cyclic motions. Matching ...

    • Efficient Sampling of Textured Scenes in Vertex Tracing 

      Ullmann, Thomas; Preidel, Thomas; Bruderlin, Beat (Eurographics Association, 2003)
      We present vertex tracing, an adaptive progressive ray tracing approach for efficient sampling of the radiance function, based on refinement in object space and subsequent reconstruction, using standard 3D graphics accelerator ...

    • Estimating Positions and Radiances of a Small Number of Light Sources for Real-Time Image-Based Lighting 

      Madsen, Claus B.; Sorensen, Mads K. D.; Vittrup, Michael (Eurographics Association, 2003)
      Image-based lighting (IBL) of virtual objects has become a popular approach to blending virtual and real scenes. In IBL an omni-directional image of a scene is used as the illumination environment for rendering virtual ...

    • Evolutionary Design of BRDFs 

      Meyer-Spradow, Jennis; Loviscach, Joern (Eurographics Association, 2003)
      The look of a non-transparent material is determined by its bidirectional reflection distribution function (BRDF). To design 3-D objects for example for games or animation films thus includes to design BRDFs. However, as ...

    • Extending the Immediate Buckling Model to Triangular Meshes for Simulating Complex Clothes 

      Choi, Kwang-Jin; Ko, Hyeong-Seok (Eurographics Association, 2003)
      The immediate buckling model is an essential element for simulating realistic cloth animations without introducing buckling instability. The original model is restricted to structured regular quad meshes, by which its use ...

    • A Framework for Video-based and Hardware-Accelerated Remote 3D-Visualization 

      Goetz, Frank; Domik, Gitta (Eurographics Association, 2003)
      This paper presents a framework for video-based and hardware-accelerated remote 3d-visualization that produces and delivers high quality video streams at an accurate frame rate. The framework is based on the portable ...

    • Generation of Radiosity Texture Atlas for Realistic Real-Time Rendering 

      Ray, Nicolas; Ulysse, Jean-Christophe; Cavin, Xavier; Levy, Bruno (Eurographics Association, 2003)
      Radiosity methods are a both physically correct and efficient way to compute the global illumination giving the visual atmosphere to a 3D scene. In this paper, we present a new approach to optimizing the visualization of ...

    • Goniometric Diagram Mapping for Hemisphere 

      Havran, Vlastimil; Dmitriev, Kirill; Seidel, Hans-Peter (Eurographics Association, 2003)
      Describing the light intensity over the hemisphere using a goniometric diagram is a common practice in the lighting industry and is prescribed for instance by IESNA (Illuminating Engineering Society of North America) ...

    • High quality images from 2.5D video 

      Berretty, Robert-Paul; Ernst, Fabian (Eurographics Association, 2003)
      Given a 2D video stream with an accompanying depth channel, we render high quality images from viewpoints close to the original one. This is for instance required to generate a 3D impression on stereoscopic or multiview ...

    • Implicit Surface Reconstruction and uniform Sampling by Striped Marching Triangles 

      Leborán, Víctor; Pardo, Xose M. (Eurographics Association, 2003)
      The synthesis of computer models from real objects is a usual procedure in medical image processing and reverse engineering. In both cases, the main issues are to reach a topologically consistent and geometrically precise ...
