    • Key Time Steps Selection for Large-Scale Time-Varying Volume Datasets Using an Information-Theoretic Storyboard 

      Zhou, Bo; Chiang, Yi-Jen (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Key time steps selection is essential for effective and efficient scientific visualization of large-scale time-varying datasets. We present a novel approach that can decide the number of most representative time steps while ...
    • Key-component Detection on 3D Meshes using Local Features 

      Sipiran, Ivan; Bustos, Benjamin (The Eurographics Association, 2012)
      In this paper, we present a method to detect stable components on 3D meshes. A component is a region on the mesh which contains discriminative local features. Our goal is to represent a 3D mesh with a set of regions, which ...
    • Key-frame Based Spatiotemporal Scribble Propagation 

      Dogan, Pelin; Aydın, Tunç Ozan; Stefanoski, Nikolce; Smolic, Aljoscha (The Eurographics Association, 2015)
      We present a practical, key-frame based scribble propagation framework. Our method builds upon recent advances in spatiotemporal filtering by adding key-components required for achieving seamless temporal propagation. To ...
    • A Key-Pose Caching System for Rendering an Animated Crowd in Real-Time 

      Lister, W.; Laycock, R.G.; Day, A.M. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a method to accelerate the visualization of large crowds of animated characters. Linear-blend skinning remains the dominant approach for animating a crowd but its efficiency can be improved by utilizing the ...
