    • Is it Necessary to Model the Matrix Degrading Enzymes for Simulating Tumour Growth? 

      Toma, Alina; Mang, Andreas; Schütz, Tina A.; Becker, Stefan; Buzug, Thorsten M. (The Eurographics Association, 2011)
      We propose a hybrid continuum discrete model to simulate tumour growth on a microscopic scale. The lattice based spatio temporal model consists of reaction diffusion equations that describe interactions between cancer ...

    • Probabilistic Inverse Dynamics for Blood Pattern Reconstruction 

      Cecchetto, Benjamin T.; Heidrich, Wolfgang (The Eurographics Association, 2011)
      We present a method of reconstructing the region of origin and trajectories for particles given impact directions and positions. This method works for nonlinear trajectories, such as parabolic motion or motion with drag ...

    • The Recognition of Ethnic Groups based on Histological Skin Properties 

      Malskies, Christoph R.; Eibenberger, Eva; Angelopoulou, Elli (The Eurographics Association, 2011)
      We present an algorithm to recognize ethnic groups based on biologically justified features, such as melanin or hemoglobin concentrations. These biophysical features are extracted from skin reflectance spectra and allow, ...

    • Seamless Integration of Multimodal Shader Compositing into a Flexible Ray Casting Pipeline 

      Arens, Stephan; Bolte, Matthias; Domik, Gitta (The Eurographics Association, 2011)
      In the last three years a number of multi-volume GPU ray casting systems have been presented. Some of them are very powerful and provide a wide variety of features. However, these approaches are either only capable of ...

    • Monocular Pose Reconstruction for an Augmented Reality Clothing System 

      Rogge, Lorenz; Neumann, Thomas; Wacker, Markus; Magnor, Marcus (The Eurographics Association, 2011)
      In this paper, we present an approach for realizing an augmented reality system for try-on of apparel. The core component of our system is a quick human pose estimation algorithm based on a single camera view only. Due to ...

    • Meshless Hierarchical Radiosity on the GPU 

      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 ...

    • Measuring BRDFs of Immersed Materials 

      Berger, Kai; Reshetouski, Ilya; Magnor, Marcus; Ihrke, Ivo (The Eurographics Association, 2011)
      We investigate the effect of immersing real-world materials into media of different refractive indices. We show, that only some materials follow the Fresnel-governed behaviour. In reality, many materials exhibit unexpected ...

    • Markerless Motion Capture using multiple Color-Depth Sensors 

      Berger, Kai; Ruhl, Kai; Schroeder, Yannic; Bruemmer, Christian; Scholz, Alexander; Magnor, Marcus (The Eurographics Association, 2011)
      With the advent of the Microsoft Kinect, renewed focus has been put on monocular depth-based motion capturing. However, this approach is limited in that an actor has to move facing the camera. Due to the active light nature ...

    • 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 ...

    • Landmark-constrained 3-D Histological Imaging: A Morphology-preserving Approach 

      Gaffling, Simone; Daum, Volker; Hornegger, Joachim (The Eurographics Association, 2011)
      The inspection of histological image sequences to gain knowledge about the original three-dimensional (3-D) morphological structure is a standard method in medical research. Its main advantage is that light microscopes ...

    • Instant Level-of-Detail 

      Grund, Nico; Derzapf, Evgenij; Guthe, Michael (The Eurographics Association, 2011)
      Highly detailed models are commonly used in computer games and other interactive rendering applications. In this context, static levels-of-detail are frequently used to achieve real-time frame rates. While this is a simple ...

    • Interactive Exploration of Polymer-Solvent Interactions 

      Thomaß, Bertram; Walter, Jonathan; Krone, Michael; Hasse, Hans; Ertl, Thomas (The Eurographics Association, 2011)
      The interaction of three-dimensional linked hydrophilic polymers with surrounding solvents in time-dependent data sets is of great interest for domain experts and current research in molecular dynamics. These polymers are ...

    • Improving Stability and Compactness in Street Layout Visualizations 

      Kratt, Julian; Strobelt, Hendrik; Deussen, Oliver (The Eurographics Association, 2011)
      We present and evaluate improvements for Street Layout, a technique that can be used for visualizing evolving hierarchical data such as file structures or software systems. Street Layouts represent data as street networks, ...

    • Assessment of Time-of-Flight Cameras for Short Camera-Object Distances 

      Stürmer, Michael; Becker, Guido; Hornegger, Joachim (The Eurographics Association, 2011)
      In this paper we have compared Time-of-Flight cameras of different vendors at object-camera distances of 500 mm, 1500 mm and 2500 mm. The aim was to find the highest possible precision at the distance of 500 mm, to estimate ...

    • Direct Visualization of Particle-Partition of Unity Data 

      Üffinger, Markus; Schweitzer, Marc Alexander; Sadlo, Filip; Ertl, Thomas (The Eurographics Association, 2011)
      Direct visualization of higher-order data provides manifold advantages over the traditional approach, which is based on resampling and subsequent visualization by interpolation-based techniques. Most important, it avoids ...

    • Effective Back-Patch Culling for Hardware Tessellation 

      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 ...

    • Data-Driven Visualization of Functional Brain Regions from Resting State fMRI Data 

      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 ...
