    • Analytic Curve Skeletons for 3D Surface Modeling and Processing 

      Thiery, Jean-Marc; Buchholz, Bert; Tierny, Julien; Boubekeur, Tamy (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present a new curve skeleton model designed for surface modeling and processing. This skeleton is defined as the geometrical integration of a piecewise harmonic parameterization defined over a disk-cylinder surface ...
    • Video Panorama for 2D to 3D Conversion 

      Ribera, Roger Blanco i; Choi, Sungwoo; Kim, Younghui; Lee, JungJin; Noh, Junyong (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Accurate depth estimation is a challenging, yet essential step in the conversion of a 2D image sequence to a 3D stereo sequence. We present a novel approach to construct a temporally coherent depth map for each image in a ...
    • Digital Camouflage Images Using Two-scale Decomposition 

      Du, Hui; Jin, Xiaogang; Mao, Xiaoyang (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present an alternative approach to create digital camouflage images which follows human's perception intuition and complies with the physical creation procedure of artists. Our method is based on a two-scale decomposition ...
    • Improving Photo Composition Elegantly: Considering Image Similarity During Composition 

      Guo, Yanwen; Liu, Ming; Gu, Tingting; Wang, Wenping (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Optimization of images with bad compositions has attracted increasing attention in recent years. Previous methods however seldomly consider image similarity when improving composition aesthetics. This may lead to significant ...
    • Registration Based Non-uniform Motion Deblurring 

      Cho, Sunghyun; Cho, Hojin; Tai, Yu-Wing; Lee, Seungyong (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      This paper proposes an algorithm which uses image registration to estimate a non-uniform motion blur point spread function (PSF) caused by camera shake. Our study is based on a motion blur model which models blur effects ...
    • Hierarchical Narrative Collage For Digital Photo Album 

      Zhang, Lei; Huang, Hua (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Collage can provide a summary form on the collection of photos in an album. In this paper, we introduce a novel approach to constructing photo collage in the hierarchical narrative manner. As opposed to previous methods ...
    • Homunculus Warping: Conveying Importance Using Self-intersection-free Non-homogeneous Mesh Deformation 

      Reinert, Bernhard; Ritschel, Tobias; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Size matters. Human perception most naturally relates relative extent, area or volume to importance, nearness and weight. Reversely, conveying importance of something by depicting it at a different size is a classic artistic ...
    • Approximate Bias Compensation for Rendering Scenes with Heterogeneous Participating Media 

      Engelhardt, Thomas; Novák, Jan; Schmidt, Thorsten-W.; Dachsbacher, Carsten (The Eurographics Association and Blackwell Publishing Ltd., 2012)
