    Surface Ricci flow is a powerful tool to design Riemannian metrics by user defined curvatures. Discrete surface Ricci flow has been broadly applied for surface parameterization, shape analysis, and computational topology. ...
  • Kaplansky, Lotan; Tal, Ayellet (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    This paper proposes a method for refining existing mesh segmentations, employing a novel extension of the active contour approach to meshes. Given a segmentation, produced either by an automatic segmentation method or ...
  • Diaz-Gutierrez, P.; Eppstein, D.; Gopi, M. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We present a graph algorithm to find fundamental cycles aligned with the principal curvature directions of a surface. Specifically, we use the tree-cotree decomposition of graphs embedded in manifolds, guided with edge ...
  • Li, Bao; Schnabel, Ruwen; Jin, Shiyao; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We consider the problem of approximating an arbitrary generic surface with a given set of simple surface primitives. In contrast to previous approaches based on variational surface approximation, which are primarily concerned ...
  • Wong, Fernando J.; Takahashi, Shigeo (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    A method for automatically generating a picture maze from two different images is introduced throughout this paper. The process begins with the extraction of salient contours and edge tangent flow information from the ...
  • Igarashi, Yuki; Igarashi, Takeo; Suzuki, Hiromasa (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We developed an interactive system to design a customized cover for a given three-dimensional (3D) object such as a camera, teapot, or car. The system first computes the convex hull of the input geometry. The user segments ...
  • Kyprianidis, Jan Eric; Kang, Henry; Doellner, Juergen (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We present a non-photorealistic rendering technique to transform color images and videos into painterly abstractions. It is based on a generalization of the Kuwahara filter that is adapted to the local shape of features, ...
  • Dammertz, Sabrina; Dammertz, Holger; Keller, Alexander; Lensch, Hendrik P. A. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    Storing textures on orthogonal tensor product lattices is predominant in computer graphics, although it is known that their sampling efficiency is not optimal. In two dimensions, the hexagonal lattice provides the maximum ...
  • Yue, Yonghao; Iwasaki, Kei; Chen, Bing-Yu; Dobashi, Yoshinori; Nishita, Tomoyuki (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    A rendering system for interior scenes is proposed in this paper. The light reaches the interior scene, usually through small regions, such as windows or abat-jours, which we call portals. To provide a solution, suitable ...
  • Pan, Minghao; Wang, Rui; Chen, Weifeng; Zhou, Kun; Bao, Hujun (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    Solving aliasing artifacts is an essential problem in shadow mapping approaches. Many works have been proposed, however, most of them focused on removing the texel-level aliasing that results from the limited resolution ...
  • Dai, Qiang; Wang, Jiaping; Liu, Yiming; Snyder, John; Wu, Enhua; Guo, Baining (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We present a new model, called the dual-microfacet, for those materials such as paper and plastic formed by a thin, transparent slab lying between two surfaces of spatially varying roughness. Light transmission through the ...
  • Liu, Yiming; Wang, Jiaping; Xue, Su; Tong, Xin; Kang, Sing Bing; Guo, Baining (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We propose a new texture editing operation called texture splicing. For this operation, we regard a texture as having repetitive elements (textons) seamlessly distributed in a particular pattern. Taking two textures as ...
  • Zhang, Guo-Xin; Cheng, Ming-Ming; Hu, Shi-Min; Martin, Ralph R. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We present a novel image resizing method which attempts to ensure that important local regions undergo a geometric similarity transformation, and at the same time, to preserve image edge structure. To accomplish this, we ...
  • Huang, Qi-xing; Mech, Radomir; Carr, Nathan (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    Smart deformation and warping tools play an important part in modern day geometric modeling systems. They allow existing content to be stretched or scaled while preserving visually salient information. To date, these ...
  • Xiao, Xuezhong; Ma, Lizhuang (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    Color transfer is an image processing technique which can produce a new image combining one source image s contents with another image s color style. While being able to produce convincing results, however, Reinhard et al. ...
  • Xu, Kun; Wang, Jiaping; Tong, Xin; Hu, Shi-Min; Guo, Baining (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We propose an efficient method for editing bidirectional texture functions (BTFs) based on edit propagation scheme. In our approach, users specify sparse edits on a certain slice of BTF. An edit propagation scheme is then ...
  • Yoon, Jong-Chul; Kam, Hyeong Ryeol; Hong, Jeong-Mo; Kang, Shin Jin; Kim, Chang-Hun (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    We propose a fast and effective technique to improve sub-grid visual details of the grid based fluid simulation. Our method procedurally synthesizes the flow fields coming from the incompressible Navier-Stokes solver and ...
  • Masood, Syed Z.; Zhu, Jiejie; Tappen, Marshall F. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    Incorrectly setting the camera s exposure can have a significant negative effect on a photograph. Over-exposing photographs causes pixels to exhibit unpleasant artifacts due to saturation of the sensor. Saturation removal ...
  • Metaaphanon, Napaporn; Bando, Yosuke; Chen, Bing-Yu; Nishita, Tomoyuki (The Eurographics Association and Blackwell Publishing Ltd, 2009)
    Woven cloth can commonly be seen in daily life and also in animation. Unless prevented in some way, woven cloth usually frays at the edges. However, in computer graphics, woven cloth is typically modeled as a continuum ...

    Gaseous fluids may move slowly, as smoke does, or at high speed, such as occurs with explosions. High-speed gas flow is always accompanied by low-speed gas flow, which produces rich visual details in the fluid motion. ...
