      Theobalt, Christian; Magnor, Marcus A.; Seidel, Hans-Peter (The Eurographics Association, 2005)
      In the talk, we give a brief overview of the research done in the Computer Graphics Group and the Graphics- Optics-Vision Group of the Max-Planck-Institut für Informatik in the area of 3D Image Analysis and Synthesis. In ...

    • Adaptive Grid Optical Tomography 

      Ihrke, Ivo; Magnor, Marcus (The Eurographics Association, 2005)
      Image-based modeling of semi-transparent, dynamic phenomena is a challenging task. We present an optical tomography method that uses an adaptive grid for the reconstruction of a three-dimensional density function from its ...

    • Advances in Shadow Removing for Motion Detection Algorithms 

      Spagnolo, P.; D'Orazio, T.; Leo, M.; Distante, A. (The Eurographics Association, 2005)
      Detecting moving objects is very important in many application contexts such as people detection and recognition, visual surveillance, automatic generation of video effects, and so on. Motion detection algorithms are very ...

    • Automatic Non-Photorealistic Rendering through Soft-Shading Removal: A Colour-Vision Approach 

      Olmos, A.; Kingdom, F. A. A. (The Eurographics Association, 2005)
      This paper presents a non-photorealistic rendering algorithm that produces "stylised-style" images by removing the soft shading from the image and by giving objects extra definition through black outlines. The method of ...

    • 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 ...

    • 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) ...

    • Correspondenceless Stereo for 3-D Iris Location 

      Anderson, Tom; Trucco, Emanuele; Razeto, Marco (The Eurographics Association, 2005)
      We present a correspondenceless stereo system locating the circular contour of an iris (limbus) in space, and therefore its 3-D plane. We avoid correspondence search completely by intersecting a bundle of conjugate epipolar ...

    • 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, ...

    • 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 ...

    • 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 ...

    • 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 ...

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

      Madsen, Claus B.; Laursen, Rune (The Eurographics Association, 2005)
