      Wang, Zhongjie; Esturo, Janick Martinez; Seidel, Hans-Peter; Weinkauf, Tino (The Eurographics Association, 2014)
      We propose a method that allows users to define flow features in form of patterns represented as sparse sets of stream line segments. Our approach finds ''similar'' occurrences in the same or other time steps. Related ...
    • Real-time Deblocked GPU Rendering of Compressed Volumes 

      Marton, Fabio; Guitián, José A. Iglesias; Díaz, Jose; Gobbetti, Enrico (The Eurographics Association, 2014)
      The wide majority of current state-of-the-art compressed GPU volume renderers are based on block-transform coding, which is susceptible to blocking artifacts, particularly at low bit-rates. In this paper we address the ...
    • Exploring Simulation in Sensor Network Models 

      Steiger, Martin; Hutter, Marco; Schader, Philipp; Kohlhammer, Jörn; Kuijper, Arjan (The Eurographics Association, 2014)
      Simulation is an important measure to estimate different properties of a planned network such as throughput and cost. However, many parameters need to be adjusted to approximate real-world conditions properly. In this paper ...
    • Deep Screen Space for Indirect Lighting of Volumes 

      Nalbach, Oliver; Ritschel, Tobias; Seidel, Hans-Peter (The Eurographics Association, 2014)
      We present a method to render approximate indirect light transport from surfaces to volumes which is fully dynamic with respect to geometry, the medium and the main light sources, running at interactive speed. This is ...
    • Progressive Spectral Ray Differentials 

      Elek, Oskar; Bauszat, Pablo; Ritschel, Tobias; Magnor, Marcus; Seidel, Hans-Peter (The Eurographics Association, 2014)
      Light travelling though refractive objects can lead to beautiful colourful illumination patterns resulting from dispersion on the object interfaces. While this can be accurately simulated by stochastic Monte-Carlo methods, ...
    • Non-local Means for Scanning Transmission Electron Microscopy Images and Poisson Noise based on Adaptive Periodic Similarity Search and Patch Regularization 

      Mevenkamp, Niklas; Yankovich, Andrew B.; Voyles, Paul M.; Berkels, Benjamin (The Eurographics Association, 2014)
      High-Angle Annular Darkfield Scanning Transmission Electron Microscopy (HAADF-STEM) allows to take images at atomic scale with a contrast proportional to the atomic number. STEM acquires an image line-by-line, pixel-by-pixel ...
    • High-Speed Object Tracking Using an Asynchronous Temporal Contrast Sensor 

      Saner, Daniel; Wang, Oliver; Heinzle, Simon; Pritch, Yael; Smolic, Aljoscha; Sorkine-Hornung, Alexander; Gross, Markus (The Eurographics Association, 2014)
      Purely image-based approaches to tracking objects in video sequences are more prone to failure the higher an object's speed, as it covers a greater distance over the camera's exposure time and is subject to increased motion ...
    • Combined Three-Dimensional Visualization of Structural Connectivity and Cortex Parcellation 

      Reichenbach, Andre; Goldau, Mathias; Hlawitschka, Mario (The Eurographics Association, 2014)
      The human cortex is organized in spatially distinct regions of different functional units. Cortex parcellations based on magnetic resonance imaging (MRI) of living human subjects are common practice, and recently, structural ...
