    • Eye-Centered Color Adaptation in Global Illumination 

      Gruson, Adrien; Ribardière, Mickael; Cozot, Remi (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Color adaptation is a well known ability of the human visual system (HVS). Colors are perceived as constant even though the illuminant color changes. Indeed, the perceived color of a diffuse white sheet of paper is still ...
    • Fast Image-Based Modeling of Astronomical Nebulae 

      Wenger, Stephan; Lorenz, Dirk; Magnor, Marcus (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Astronomical nebulae are among the most complex and visually appealing phenomena known outside the bounds of the Solar System. However, our fixed vantage point on Earth limits us to a single known view of these objects, ...
    • Garment Modeling from a Single Image 

      Zhou, Bin; Chen, Xiaowu; Fu, Qiang; Guo, Kan; Tan, Ping (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Modeling of realistic garments is essential for online shopping and many other applications including virtual characters. Most of existing methods either require a multi-camera capture setup or a restricted mannequin pose. ...

    • Guided Real-Time Scanning of Indoor Objects 

      Kim, Young Min; Mitra, Niloy J.; Huang, Qixing; Guibas, Leonidas (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Advances in 3D acquisition devices provide unprecedented opportunities for quickly scanning indoor environments. Such raw scans, however, are often noisy, incomplete, and significantly corrupted, making semantic scene ...
    • Hair Interpolation for Portrait Morphing 

      Weng, Yanlin; Wang, Lvdi; Li, Xiao; Chai, Menglei; Zhou, Kun (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper we study the problem of hair interpolation: given two 3D hair models, we want to generate a sequence of intermediate hair models that transform from one input to another both smoothly and aesthetically pleasing. ...
