    • Efficient 3D Content Creation using Point Sampled Geometry 

      Gross, Markus (The Eurographics Association, 2003)
      In recent years, point primitives have received a growing attention in computer graphics. The emergence of affordable 3D scanning devices along with the demand for ever more geometric detail has created the need to efficiently ...

    • An Eigenvector Method for Surface Recovery 

      Robles-Kelly, A.; Hancock, E.R. (The Eurographics Association, 2003)
      In this paper we explore how spectral methods for graph seriation can be used to develop a new shape-fromshading algorithm. We characterise the field of surface normals using a transition matrix whose elements are computed ...

    • 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 ...

    • Extending Natural Textures with Multi-Scale Synthesis 

      Stahlhut, O. (The Eurographics Association, 2003)
      This paper presents a texture synthesis algorithm that was designed for the tile-less generation of large images of arbitrary size from small sample images. The synthesised texture shows features that are visually similar ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • Learnt Inverse Kinematics for Animation Synthesis 

      Ong, Eng-Jon; Hilton, Adrian (The Eurographics Association, 2005)
      Existing work on animation synthesis can be roughly split into two approaches, those that combine segments of motion capture data, and those that perform inverse kinematics. In this paper, we present a method for performing ...

    • Linear Hashtable Method and Predicted Hexagonal Search Algorithm with Moments Invariant 

      Wu, Yunsong; Megson, Graham; Nie, Zhengang; Liu, Xuan (The Eurographics Association, 2005)
      This paper presents a novel Linear Hashtable Method Predicted Hexagonal Search (LHMPHS) method for block base motion compensation on the basis of research from previous algorithm. Hashtable is used in video compression. ...

    • Merging Graphics and Vision for 3D Face Recognition 

      Bai, Li; Song, Yi (The Eurographics Association, 2005)
      This paper presents a new approach to automatic 3D face modelling from unstructured point cloud data. An efficient B-Spline surface-fitting algorithm is used to obtain an initial parametric surface for each face point cloud ...
