      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 ...
    • 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. ...
    • Gradient-based Interpolation and Sampling for Real-time Rendering of Inhomogeneous, Single-scattering Media 

      Ren, Zhong; Zhou, Kun; Lin, Stephen; Guo, Baining (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a real-time rendering algorithm for inhomogeneous, single scattering media, where all-frequency shading effects such as glows, light shafts, and volumetric shadows can all be captured. The algorithm first computes ...
    • A Hidden-picture Puzzles Generator 

      Yoon, Jong-Chul; Lee, In-Kwon; Kang, Henry (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      A hidden-picture puzzle contains objects hidden in a background image, in such a way that each object fits closely into a local region of the background. Our system converts image of the background and objects into line ...
    • Interactive Global Illumination for Deformable Geometry in CUDA 

      Schmitz, Arne; Tavenrath, Markus; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Interactive global illumination for fully deformable scenes with dynamic relighting is currently a very elusive goal in the area of realistic rendering. In this work we propose a system that is based on explicit visibility ...
    • Interactive Glossy Reflections using GPU-based Ray Tracing with Adaptive LOD 

      Yu, Xuan; Wang, Rui; Yu, Jingyi (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an interactive GPU-based algorithm for accurately rendering high-quality, dynamic glossy reflection effects from both HDR environment maps and local scene objects. Our method uses hardware rasterization to produce ...
    • Interpolatory and Mixed Loop Schemes 

      Shi, Zhuo; Lin, Shujin; Luo, Xiaonan; Wang, Renhong (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a new interpolatory Loop scheme and an unified and mixed interpolatory and approximation subdivision scheme for triangular meshes. The former which is C1 continuous as same as the modified Butterfly ...
    • 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 ...
    • Local Volume Preservation for Skinned Characters 

      Rohmer, Damien; Hahmann, Stefanie; Cani, Marie-Paule (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Generating plausible deformations of a character skin within the standard production pipeline is a challenge. This paper presents a volume preservation method dedicated to skinned characters. As usual, the character is ...
    • Online Personalised Non-photorealistic Rendering Technique for 3D Geometry from Incremental Sketching
