      In this paper we study the estimation of dense, instantaneous 3D motion fields over a non-rigidly moving surface observed by multi-camera systems. The motivation arises from multi-camera applications that require motion ...
    • Adaptive Level-of-Precision for GPU-Rendering 

      Meyer, Quirin; Sussner, Gerd; Greiner, Günter; Stamminger, Marc (The Eurographics Association, 2011)
      Video memory is a valuable resource that has grown much slower than the rendering power of GPUs over the last years. Today, video memory is often the limiting factor in interactive high-quality rendering applications. The ...

      Crippa, Alessandro; Roerdink, Jos B.T.M. (The Eurographics Association, 2011)
      Functional parcellation of the human cortex plays an important role in the understanding of brain functions. Tradi- tionally, functional areas are defined according to anatomical landmarks. Recently, new techniques were ...

      Zollhöfer, Michael; Stamminger, Marc (The Eurographics Association, 2011)
      Meshless radiosity is a radiosity method that is based on a point-based hierarchical discretization of the scene. This better decouples the runtime complexity from the geometric complexity of the scene and allows for an ...

      Manakov, Alkhazur; Seidel, Hans-Peter; Ihrke, Ivo (The Eurographics Association, 2011)
      Laser galvanometric scanning systems are commonly used in various fields such as three dimensional scanning, medical imaging, material processing, measurement devices and laser display systems. The systems of such kind ...
    • Implicit Filtering for Image and Shape Processing 

      Belyaev, Alexander; Yamauchi, Hitoshi (The Eurographics Association, 2011)
      The main purpose of this paper consists of demonstrating advantages of using implicit filtering schemes (noncausal IIR filters, in the signal processing language) for some basic image processing and geometric modeling ...
    • Partial Symmetry Detection in Volume Data 

      Kerber, Jens; Wand, Michael; Krüger, Jens; Seidel, Hans-Peter (The Eurographics Association, 2011)
      In this paper, we present an algorithm for detecting partial Euclidean symmetries in volume data. Our algorithm finds subsets in voxel data that map to each other approximately under translations, rotations, and reflections. ...
    • Simulating Deep Sea Underwater Images Using Physical Models for Light Attenuation, Scattering, and Refraction 

      Sedlazeck, Anne; Koch, Reinhard (The Eurographics Association, 2011)
      When adapting computer vision algorithms to underwater imaging, two major differences in image formation occur. While still traveling through the water, light rays are scattered and absorbed depending on their wavelength, ...
    • Warp-based Near-Regular Texture Analysis for Image-based Texture Overlay 

      Hilsmann, Anna; Schneider, David C.; Eisert, Peter (The Eurographics Association, 2011)
      Image-based texture overlay or retexturing is the process of augmenting a surface in an image or a video sequence with a new, synthetic texture. Some properties of the original texture such as texture distortion as well ...
    • SBL Mesh Filter: A Fast Separable Approximation of Bilateral Mesh Filtering 

      Vialaneix, Guillaume; Boubekeur, Tamy (The Eurographics Association, 2011)
      Bilateral mesh filtering is a simple and powerful feature-preserving filtering operator which allows to smooth or remove noise from surface meshes while preserving important features in a non-iterative way. However, to be ...
    • Koiter's Thin Shells on Catmull-Clark Limit Surfaces 

      Wawrzinek, Anna; Hildebrandt, Klaus; Polthier, Konrad (The Eurographics Association, 2011)
      We present a discretization of Koiter's model of elastic thin shells based on a finite element that employs limit surfaces of Catmull Clark's subdivision scheme. The discretization can directly be applied to control grids ...
    • Real-time Rendering of Stack-based Terrains 

      Löffler, Falko; Müller, Andreas; Schumann, Heidrun (The Eurographics Association, 2011)
      Usually, terrain rendering relies on a 2D regular grid of height values, the so called height field. Height fields describe 2.5D surfaces and are not able to present complex 3D terrain features. In contrast, a 3D data ...
    • Extrinsic Self-Calibration of Time-of-Flight Cameras using a Combination of 3D and Intensity Descriptors 

      Schmidt, Jörn; Brückner, Marcel; Denzler, Joachim (The Eurographics Association, 2011)
      Time-of-Flight (ToF) cameras are able to simultaneously record intensity and depth images at a high frequency. Many applications require images that are recorded from different viewpoints. In order to consolidate the ...
    • A Framework for Interactive Visualization and Classification of Dynamical Processes at the Water Surface 

      Wanner, Sven; Sommer, Christoph; Rocholz, Roland; Jung, Michael; Hamprecht, Fred; Jähne, Bernd (The Eurographics Association, 2011)
      A framework for the visualization and classification of multi-channel spatio-temporal data from water wave imaging is presented. Our interactive visualization tool, WaveVis, allows a detailed study of the water surface ...

      Loop, Charles; Nießner, Matthias; Eisenacher, Christian (The Eurographics Association, 2011)
      When rendering objects with hardware tessellation, back-facing patches should be culled as early as possible to avoid unnecessary surface evaluations, and setup costs for the tessellator and rasterizer. For dynamic objects ...
