    • Interactive Appearance Editing in RGB-D Images 

      Bergmann, Stephan; Ritschel, Tobias; Dachsbacher, Carsten (The Eurographics Association, 2014)
      The availability of increasingly powerful and affordable image and depth sensors in conjunction with the necessary processing power creates novel possibilities for more sophisticated and powerful image editing tools. Along ...
    • 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 ...
    • On the Suitability of Connectivity-Extended Local Embedding for Drawing Multivariate Graphs 

      Fahnenschreiber, Sebastian; Laux, Melvin; Landesberger, Tatiana von (The Eurographics Association, 2014)
      Multivariate networks are present in various domains such as biology, or social science. In such networks, the nodes often have several quantitative attributes, which determine similarity of nodes (e.g., person's characteristics ...
    • Online Adaptive PCA for Inverse Kinematics Hand Tracking 

      Schröder, Matthias; Botsch, Mario (The Eurographics Association, 2014)
      Recent approaches to real-time bare hand tracking estimate the hand's pose and posture by fitting a virtual hand model to RGBD sensor data using inverse kinematics. It has been shown that exploiting natural hand synergies ...
    • Pattern Search in Flows based on Similarity of Stream Line Segments 

      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 ...
    • 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, ...
    • Real-time Canonical-angle Views in 3D Virtual Cities 

      Kol, Timothy R.; Liao, Jingtang; Eisemann, Elmar (The Eurographics Association, 2014)
      Virtual city models are useful for navigation planning or the investigation of unknown regions. However, existing rendering systems often fail to provide optimal views during the exploration, introduce occlusions, or show ...
    • 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 ...
    • Real-time Reflective and Refractive Novel-view Synthesis 

      Lochmann, Gerrit; Reinert, Bernhard; Ritschel, Tobias; Müller, Stefan; Seidel, Hans-Peter (The Eurographics Association, 2014)
      We extend novel-view image synthesis from the common diffuse and opaque image formation model to the reflective and refractive case. Our approach uses a ray tree of RGBZ images, where each node contains one RGB light path ...
    • SOAR: Stochastic Optimization for Affine global point set Registration 

      Agus, Marco; Gobbetti, Enrico; Villanueva, Alberto Jaspe; Mura, Claudio; Pajarola, Renato (The Eurographics Association, 2014)
      We introduce a stochastic algorithm for pairwise affine registration of partially overlapping 3D point clouds with unknown point correspondences. The algorithm recovers the globally optimal scale, rotation, and translation ...
    • Supporting Urban Search & Rescue Mission Planning through Visualization-Based Analysis 

      Bock, Alexander; Kleiner, Alexander; Lundberg, Jonas; Ropinski, Timo (The Eurographics Association, 2014)
      We propose a visualization system for incident commanders in urban search & rescue scenarios that supports access path planning for post-disaster structures. Utilizing point cloud data acquired from unmanned robots, ...
    • Towards Efficient Online Compression of Incrementally Acquired Point Clouds 

      Golla, Tim; Schwartz, Christopher; Klein, Reinhard (The Eurographics Association, 2014)
      We present a framework for the online compression of incrementally acquired point cloud data. For this, we extend an existing vector quantization-based offline point cloud compression algorithm to handle the challenges ...
