    • Efficient Mean-shift Clustering Using Gaussian KD-Tree 

      Xiao, Chunxia; Liu, Meng (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Mean shift is a popular approach for data clustering, however, the high computational complexity of the mean shift procedure limits its practical applications in high dimensional and large data set clustering. In this ...

    • An Example-based Approach to Synthesize Artistic Strokes using Graphs 

      Kim, Mikyung; Shin, Hyun Joon (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In this paper, we propose a technique to produce artistic strokes in a variety of drawing material based on example images. Our approach is to divide example strokes scanned from images into small pieces along their stroke ...

      Iwasaki, K.; Uchida, H.; Dobashi, Y.; Nishita, T. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      The visual simulation of natural phenomena has been widely studied. Although several methods have been proposed to simulate melting, the flows of meltwater drops on the surfaces of objects are not taken into account. In ...

    • Fast Updating of Delaunay Triangulation of Moving Points by Bi-cell Filtering 

      Zhou, Yuanfeng; Sun, Feng; Wang, Wenping; Wang, Jiaye; Zhang, Caiming (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Updating a Delaunay triangulation when data points are slightly moved is the bottleneck of computation time in variational methods for mesh generation and remeshing. Utilizing the connectivity coherence between two consecutive ...

    • Feature based terrain generation using diffusion equation 

      Hnaidi, Houssam; Guerin, Eric; Akkouche, Samir; Peytavie, Adrien; Galin, Eric (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This paper presents a diffusion method for generating terrains from a set of parameterized curves that characterize the landform features such as ridge lines, riverbeds or cliffs. Our approach provides the user with an ...

    • Feature Oriented Progressive Lossless Mesh Coding 

      Peng, Jingliang; Huang, Yan; Kuo, C.-C. Jay; Eckstein, Ilya; Gopi, M. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      A feature-oriented generic progressive lossless mesh coder (FOLProM) is proposed to encode triangular meshes with arbitrarily complex geometry and topology. In this work, a sequence of levels of detail (LODs) are generated ...

    • Frontmatter PG 2010 

      Unknown author (The Eurographics Association and Blackwell Publishing Ltd, 2010)

    • Image Synthesis for Branching Structures 

      Sibbing, Dominik; Pavic, Darko; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a set of techniques for the synthesis of artificial images that depict branching structures like rivers, cracks, lightning, mountain ranges, or blood vessels. The central idea is to build a statistical model ...

    • Instant Propagation of Sparse Edits on Images and Videos 

      Li, Yong; Ju, Tao; Hu, Shi-Min (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      The ability to quickly and intuitively edit digital contents has become increasingly important in our everyday life. We propose a novel method for propagating a sparse set of user edits (e.g., changes in color, brightness, ...

    • L4RW: Laziness-based Realistic Real-time Responsive Rebalance in Walking 

      Xu, Mingliang; Li, Huansen; Lv, Pei; Chen, Wenzhi; Liu, Gengdai; Zhu, Pengyu; Pan, Zhigeng (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a novel L4RW (Laziness-based Realistic Real-time Responsive Rebalance in Walking) technique to synthesize 4RW animations under unexpected external perturbations with minimal locomotion effort. We first devise a ...

    • Least Squares Subdivision Surfaces 

      Boye, S.; Guennebaud, G.; Schlick, C. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      The usual approach to design subdivision schemes for curves and surfaces basically consists in combining proper rules for regular configurations, with some specific heuristics to handle extraordinary vertices. In this ...

    • Manifold-Based 3D Face Caricature Generation with Individualized Facial Feature Extraction 

      Wang, S.F.; Lai, S.H. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Caricature is an interesting art to express exaggerated views of different persons and things through drawing. The face caricature is popular and widely used for different applications. To do this, we have to properly ...

    • Metalights: Improved Interleaved Shading 

      Faure, William; Chang, Chun-Fa (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present metalights, a novel Virtual Point Light (VPL) encapsulating structure which enhances classic interleaved shading by improving VPL sampling, based on few initial screen space samples to estimate VPL contribution ...

    • Modeling Complex Unfoliaged Trees from a Sparse Set of Images 

      Lopez, Luis D.; Ding, Yuanyuan; Yu, Jingyi (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a novel image-based technique for modeling complex unfoliaged trees. Existing tree modeling tools either require capturing a large number of views for dense 3D reconstruction or rely on user inputs and botanic ...

    • Modeling of Clouds from a Single Photograph 

      Dobashi, Yoshinori; Shinzo, Yusuke; Yamamoto, Tsuyoshi (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In this paper, we propose a simple method for modeling clouds from a single photograph. Our method can synthesize three types of clouds: cirrus, altocumulus, and cumulus. We use three different representations for each ...
