    • Use of Computer Vision/ Computer Graphics Collaboration for 3D Rotoscopy 

      Gagalowicz, André (The Eurographics Association, 2005)
      This talk introduces 3D rotoscopy and its role in post-production applications, and the computer vision/computer graphics strategies used. The case of rigid objects is presented first, for which well-established approaches ...

    • Bitvectors for Robust Hierarchical Template Matching 

      Tweed, David (The Eurographics Association, 2005)
      Many target detection problems involve objects where the primary variability in appearance is due to changes amongst characteristic configurations (as opposed to the systematic variability of object rotation or illumination ...

    • Depth Enhanced Panoramas 

      Bahmutov, Gleb; Popescu, Voicu; Mudure, Mihai; Sacks, Elisha (The Eurographics Association, 2005)
      Depth enhanced panoramas are a practical solution to the difficult problem of inside-looking-out modeling. Depth enhanced panoramas extend color panoramas to support viewpoint translation, while retaining their speed, ...

    • Visual Modeling: Unifying Graphics and Vision 

      Terzopoulos, Demetri (The Eurographics Association, 2005)
      The computer vision and computer graphics fields have been developing largely independently since their genesis in the early 1960s. However, there is now a significant amount of exciting research at the intersection of ...

    • A New Framework for Trademark Retrieval Based on Size Functions 

      Cerri, A.; Ferri, M.; Giorgi, D. (The Eurographics Association, 2005)
      We propose a new, effective system for Content Based trademark retrieval, which involves Size Functions. Three different classes of shape descriptors are combined, for a total amount of 25 measuring functions. The evaluation ...

    • Modeling Falling and Accumulating Snow 

      Moeslund, T. B.; Madsen, C. B.; Aagaard, M.; Lerche, D. (The Eurographics Association, 2005)
      The use of computer graphics to produce special effects is currently being applied with great results in especially the entertainment and game industry. One area where computer graphics is not quite ready to replace all ...

    • A Model-Based Approach to Image Relighting with a Potential for Real-Time Implementation 

      Madsen, Claus B.; Laursen, Rune (The Eurographics Association, 2005)
      Image relighting is a very unique special visual effect which promises to have many important practical applications. Image relighting is essentially the process of, given one or more images of some scene, computing what ...

    • Realistic Real-Time Hair Simulation and Rendering 

      Jung, Yvonne; Rettig, Alexander; Klar, Oliver; Lehr, Timo (The Eurographics Association, 2005)
      We present a method for realistic rendering and simulation of human hair in real-time, which is suitable for the use in complex virtual reality applications. Neighbouring hairs are combined into wisps and animated with our ...

    • Different Medical Modelling Strategies in a Single Collaborative Immersive Virtual Environment 

      Al-khalifah, A.; McCrindle, R.; Alexandrov, V. (The Eurographics Association, 2005)
      Visualisation and simulation systems are becoming increasingly popular nowadays in medical planning and training. These tools are built using various technologies, such as computer graphics, Virtual Reality, and three ...

    • A Rigid Transform Basis for Animation Compression and Level of Detail 

      Collins, G.; Hilton, A. (The Eurographics Association, 2005)
      We present a scheme for achieving level of detail and compression for animation sequences with known constant connectivity. We suggest compression is useful to automatically create low levels of detail in animations which ...

    • Visual Recognition of Man-made Materials and Structures in an Office Environment 

      Song, Y. Z.; Town, C. P. (The Eurographics Association, 2005)
      This paper demonstrates a new approach towards object recognition founded on the development of Neural Network classifiers and Bayesian Networks. The mapping from segmented image region descriptors to semantically meaningful ...

    • Image classification using compression distance 

      Lan, Yuxuan; Harvey, Richard (The Eurographics Association, 2005)
      The normalised compression distance measures the mutual compressibility of two signals. We show that this distance can be used for classification on real images. Furthermore, the same compressor can also operate on derived ...

    • Natural Image Matting 

      Hillman, Peter M.; Hannah, John M. (The Eurographics Association, 2005)
      Matte pulling - generating greyscale images which indicate segmentation of images into elements with subpixel accuracy and where blur causes pixels to be a mixture of elements - has received attention in recent years. Many ...

    • Color Reduction by Using a new Self-Growing and Self-Organized Neural Network 

      Atsalakis, A.; Papamarkos, N. (The Eurographics Association, 2005)
      A new method for the reduction of the number of colors in a digital image is proposed. The new method is based on the developed of a new neural network classifier that combines the advantages of the Growing Neural Gas (GNG) ...

    • Sensitivity Analysis in Image Synthesis 

      Trujillo, M.; Izquierdo, E. (The Eurographics Association, 2005)
      Intermediate virtual images are used in the evaluation of disparity estimations. The analysis is based on the effect of disparity inaccuracies in the relative quality of virtual images. The peak-signal-to-noise ratio and ...
