  • Efficient Shadow Removal Using Subregion Matching Illumination Transfer 

    Xiao, Chunxia; Xiao, Donglin; Zhang, Ling; Chen, Lin (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    This paper proposes a new shadow removal approach for input single natural image by using subregion matching illumination transfer. We first propose an effective and automatic shadow detection algorithm incorporating global ...
  • EnvyDepth: An Interface for Recovering Local Natural Illumination from Environment Maps 

    Banterle, Francesco; Callieri, Marco; Dellepiane, Matteo; Corsini, Massimiliano; Pellacini, Fabio; Scopigno, Roberto (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    In this paper, we present EnvyDepth, an interface for recovering local illumination from a single HDR environment map. In EnvyDepth, the user quickly indicates strokes to mark regions of the environment map that should be ...
  • Learning to Predict Localized Distortions in Rendered Images 

    Cadík, Martin; Herzog, Robert; Mantiuk, Rafal; Mantiuk, Radoslaw; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    In this work, we present an analysis of feature descriptors for objective image quality assessment. We explore a large space of possible features including components of existing image quality metrics as well as many ...
  • An Efficient and Scalable Image Filtering Framework Using VIPS Fusion 

    Zhang, Jun; Chen, Xiuhong; Zhao, Yan; Li, H. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Edge-preserving image filtering is a valuable tool for a variety of applications in image processing and computer vision. Motivated by a new simple but effective local Laplacian filter, we propose a scalable and efficient ...
  • As-Rigid-As-Possible Distance Field Metamorphosis 

    Weng, Yanlin; Chai, Menglei; Xu, Weiwei; Tong, Yiying; Zhou, Kun (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Widely used for morphing between objects with arbitrary topology, distance field interpolation (DFI) handles topological transition naturally without the need for correspondence or remeshing, unlike surface-based interpolation ...
  • Coarse-to-Fine Normal Filtering for Feature-Preserving Mesh Denoising Based on Isotropic Subneighborhoods 

    Zhu, Lei; Wie, Mingqiang; Yu, Jinze; Wang, Weiming; Qin, Jing; Heng, Pheng-Ann (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    State-of-the-art normal filters usually denoise each face normal using its entire anisotropic neighborhood. However, enforcing these filters indiscriminately on the anisotropic neighborhood will lead to feature blurring, ...
  • Polar NURBS Surface with Curvature Continuity 

    Shi, Kan-Le; Yong, Jun-Hai; Tang, Lei; Sun, Jia-Guang; Paul, Jean-Claude (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Polar NURBS surface is a kind of periodic NURBS surface, one boundary of which shrinks to a degenerate polar point. The specific topology of its control-point mesh offers the ability to represent a cap-like surface, which ...
  • Symmetry Robust Descriptor for Non-Rigid Surface Matching 

    Zhang, Zhiyuan; Yin, KangKang; Foong, Kelvin W. C. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    In this paper, we propose a novel shape descriptor that is robust in differentiating intrinsic symmetric points on geometric surfaces. Our motivation is that even the state-of-the-art shape descriptors and non-rigid surface ...
  • Level-of-Detail Streaming and Rendering using Bidirectional Sparse Virtual Texture Functions 

    Schwartz, Christopher; Ruiters, Roland; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Bidirectional Texture Functions (BTFs) are among the highest quality material representations available today and thus well suited whenever an exact reproduction of the appearance of a material or complete object is required. ...
  • Improving Memory Space Efficiency of Kd-tree for Real-time Ray Tracing 

    Choi, Byeongjun; Chang, Byungjoon; Ihm, Insung (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Compared with its competitors such as the bounding volume hierarchy, a drawback of the kd-tree structure is that a large number of triangles are repeatedly duplicated during its construction, which often leads to inefficient, ...
  • A Programmable Graphics Processor based on Partial Stream Rewriting 

    Middendorf, Lars; Haubelt, Christian (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Current graphics processing units (GPU) typically offer only a limited number of programmable pipeline stages, whose usage, data flow and topology are mostly fixed. Although a more flexible, custom rendering pipeline can ...
  • Adaptive Ray-bundle Tracing with Memory Usage Prediction: Efficient Global Illumination in Large Scenes 

    Tokuyoshi, Yusuke; Sekine, Takashi; Silva, Tiago da; Kanai, Takashi (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    This paper proposes an adaptive rendering technique for ray-bundle tracing. Ray-bundle tracing can be done by per-pixel linked-list construction on a GPU rasterization pipeline. This rasterization based approach offers ...
  • Boundary-Aware Extinction Mapping 

    Gautron, Pascal; Delalandre, Cyril; Marvie, Jean-Eudes; Lecocq, Pascal (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    We introduce Boundary-Aware Extinction Maps for interactive rendering of massive heterogeneous volumetric datasets. Our approach is based on the projection of the extinction along light rays into a boundary-aware function ...
  • Still-Frame Simulation for Fire Effects of Images 

    Son, Minjung; Kim, Byungmoon; Wilensky, Gregg; Lee, Seungyong (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    We propose various simulation strategies to generate single-frame fire effects for images, as opposed to multiframe fire effects for animations. To accelerate 3D simulation and to provide a user with early hints on the ...
  • Animated 3D Line Drawings with Temporal Coherence 

    Xu, Xiang; Seah, Hock Soon; Quah, Chee Kwang (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Producing traditional animation is a laborious task where the key drawings are first drawn by artists and thereafter inbetween drawings are created, whether it is by hand or computer-assisted. Auto-inbetweening of these ...
  • Evaluation of Tone Mapping Operators for HDR-Video 

    Eilertsen, Gabriel; Wanat, Robert; Mantiuk, Rafal K.; Unger, Jonas (The Eurographics Association and Blackwell Publishing Ltd., 2013)

  • Multiplane Video Stabilization 

    Wang, Zhong-Qiang; Zhang, Lei; Huang, Hua (The Eurographics Association and Blackwell Publishing Ltd., 2013)

  • Learning and Applying Color Styles From Feature Films 

    Xue, Su; Agarwala, Aseem; Dorsey, Julie; Rushmeier, Holly (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Directors employ a process called ''color grading'' to add color styles to feature films. Color grading is used for a number of reasons, such as accentuating a certain emotion or expressing the signature look of a director. ...
  • A Progressive Tri-level Segmentation Approach for Topology-Change-Aware Video Matting 

    Ju, Jinlong; Wang, Jue; Liu, Yebin; Wang, Haoqian; Dai, Qionghai (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Previous video matting approaches mostly adopt the ''binary segmentation + matting'' strategy, i.e., first segment each frame into foreground and background regions, then extract the fine details of the foreground boundary ...
