    • Progressive Interpolation based on Catmull-Clark Subdivision Surfaces 

      Chen, Zhongxian; Luo, Xiaonan; Tan, Le; Ye, Binghong; Chen, Jiapeng (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We introduce a scheme for constructing a Catmull-Clark subdivision surface that interpolates the vertices of a quadrilateral mesh with arbitrary topology. The basic idea here is to progressively modify the vertices of an ...

    • A Biorthogonal Wavelet Approach based on Dual Subdivision 

      Zhang, Hui; Qin, Guiming; Qin, Kaihuai; Sun, Hanqiu (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper a biorthogonal wavelet approach based on Doo-Sabin subdivision is presented. In the dual subdivision like Doo-Sabin scheme, all the old control vertices disappear after one subdivision step, which is a big ...

    • Shrinkability Maps for Content-Aware Video Resizing 

      Zhang, Yi-Fei; Hu, Shi-Min; Martin, Ralph R. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      A novel method is given for content-aware video resizing, i.e. targeting video to a new resolution (which may involve aspect ratio change) from the original.We precompute a per-pixel cumulative shrinkability map which takes ...

    • Capturing Intention-based Full-Frame Video Stabilization 

      Chen, Bing-Yu; Lee, Ken-Yi; Huang, Wei-Ting; Lin, Jong-Shan (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Annoying shaky motion is one of the significant problems in home videos, since hand shake is an unavoidable effect when capturing by using a hand-held camcorder. Video stabilization is an important technique to solve this ...

    • View and Time Interpolation in Image Space 

      Stich, Timo; Linz, Christian; Albuquerque, Georgia; Magnor, Marcus (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The ability to interpolate between images taken at different time and viewpoints directly in image space opens up new possiblities. The goal of our work is to create plausible in-between images in real time without the ...

    • Sketching MLS Image Deformations On the GPU 

      Weng, Yanlin; Shi, Xiaohan; Bao, Hujun; Zhang, Jun (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper, we present an image editing tool that allows the user to deform images using a sketch-based interface. The user simply sketches a set of source curves in the input image, and also some target curves that the ...

    • Example-based Multiple Local Color Transfer by Strokes 

      Wen, Chung-Lin; Hsieh, Chang-Hsi; Chen, Bing-Yu; Ouhyoung, Ming (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper investigates a new approach for color transfer. Rather than transferring color from one image to another globally, we propose a system with a stroke-based user interface to provide a direct indication mechanism. ...

    • Shape-simplifying Image Abstraction 

      Kang, Henry; Lee, Seungyong (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a simple algorithm for producing stylistic abstraction of a photograph. Based on mean curvature flow in conjunction with shock filter, our method simplifies both shapes and colors simultaneously while ...

    • Perceptual Evaluation of Color-to-Grayscale Image Conversions 

      Cadik, M. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Color images often have to be converted to grayscale for reproduction, artistic purposes, or for subsequent processing. Methods performing the conversion of color images to grayscale aim to retain as much information about ...

    • Distortion Optimization based Image Completion from a Large Displacement View 

      Liu, Chunxiao; Yang, Yingzhen; Peng, Qunsheng; Wang, Jin; Chen, Wei (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new image completion method based on an additional large displacement view (LDV) of the same scene for faithfully repairing large missing regions on the target image in an automatic way. A coarse-to-fine ...

    • Knitting a 3D Model 

      Igarashi, Yuki; Igarashi, Takeo; Suzuki, Hiromasa (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      A knitted animal is made of a closed surface consisting of several knitted patches knitted out of yarn and stuffed with cotton (Fig. 1). We introduce a system to create a knitting pattern from a given 3D surface model ...

    • Reconstructing 3D Shape, Albedo and Illumination from a Single Face Image 

      Wang, S. F.; Lai, S. H. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The morphable model has been employed to efficiently describe 3D face shape and the associated albedo with a reduced set of basis vectors. The spherical harmonics (SH) model provides a compact basis to well approximate the ...

    • Reconstructing head models from photographs for individualized 3D-audio processing 

      Dellepiane, M.; Pietroni, N.; Tsingos, N.; Asselot, M.; Scopigno, R. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Visual fidelity and interactivity are the main goals in Computer Graphics research, but recently also audio is assuming an important role. Binaural rendering can provide extremely pleasing and realistic three-dimensional ...

    • The Craniofacial Reconstruction from the Local Structural Diversity of Skulls 

      Pei, Yuru; Zha, Hongbin; Yuan, Zhongbiao (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The craniofacial reconstruction is employed as an initialization of the identification from skulls in forensics. In this paper, we present a two-level craniofacial reconstruction framework based on the local structural ...

    • Polyhedral Finite Elements Using Harmonic Basis Functions 

      Martin, Sebastian; Kaufmann, Peter; Botsch, Mario; Wicke, Martin; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Finite element simulations in computer graphics are typically based on tetrahedral or hexahedral elements, which enables simple and efficient implementations, but in turn requires complicated remeshing in case of topological ...

    • Maximum Entropy Coordinates for Arbitrary Polytopes 

      Hormann, K.; Sukumar, N. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Barycentric coordinates can be used to express any point inside a triangle as a unique convex combination of the triangle s vertices, and they provide a convenient way to linearly interpolate data that is given at the ...

    • Pointwise radial minimization: Hermite interpolation on arbitrary domains 

      Floater, M. S.; Schulz, C. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we propose a new kind of Hermite interpolation on arbitrary domains, matching derivative data of arbitrary order on the boundary. The basic idea stems from an interpretation of mean value interpolation as the ...

    • A Local/Global Approach to Mesh Parameterization 

      Liu, Ligang; Zhang, Lei; Xu, Yin; Gotsman, Craig; Gortler, Steven J. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a novel approach to parameterize a mesh with disk topology to the plane in a shape-preserving manner. Our key contribution is a local/global algorithm, which combines a local mapping of each 3D triangle to the ...

    • Motorcycle Graphs: Canonical Quad Mesh Partitioning 

      Eppstein, David; Goodrich, Michael T.; Kim, Ethan; Tamstorf, Rasmus (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We describe algorithms for canonically partitioning semi-regular quadrilateral meshes into structured submeshes, using an adaptation of the geometric motorcycle graph of Eppstein and Erickson to quad meshes. Our partitions ...
