  • Efficient Opacity Specification Based on Feature Visibilities in Direct Volume Rendering 

    Wang, Yunhai; Zhang, Jian; Chen, Wei; Zhang, Huai; Chi, Xuebin (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Due to 3D occlusion, the specification of proper opacities in direct volume rendering is a time-consuming and unintuitive process. The visibility histograms introduced by Correa and Ma reflect the effect of occlusion by ...
  • Intelligent GPGPU Classification in Volume Visualization: A framework based on Error-Correcting Output Codes 

    Escalera, Sergio; Puig, Anna; Amoros, Oscar; Salamó, Maria (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    In volume visualization, the definition of the regions of interest is inherently an iterative trial-and-error process finding out the best parameters to classify and render the final image. Generally, the user requires a ...
  • Optimized Topological Surgery for Unfolding 3D Meshes 

    Takahashi, Shigeo; Wu, Hsiang-Yun; Saw, Seow Hui; Lin, Chun-Cheng; Yen, Hsu-Chun (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Constructing a 3D papercraft model from its unfolding has been fun for both children and adults since we can reproduce virtual 3D models in the real world. However, facilitating the papercraft construction process is still ...
  • Heat Walk: Robust Salient Segmentation of Non-rigid Shapes 

    Benjamin, William; Polk, Andrew Wood; Vishwanathan, S. V. N.; Ramani, Karthik (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Segmenting three dimensional objects using properties of heat diffusion on meshes aim to produce salient results. The few existing algorithms based on heat diffusion do not use the full knowledge that can be gained from ...
  • Computing 3D Shape Guarding and Star Decomposition 

    Yu, Wuyi; Li, Xin (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    This paper proposes an effective framework to compute the visibility guarding and star decomposition of 3D solid shapes. We propose a progressive integer linear programming algorithm to solve the guarding points that can ...
  • A Single Image Representation Model for Efficient Stereoscopic Image Creation 

    Kim, Younghui; Jung, Hwi-ryong; Choi, Sungwoo; Lee, Jungjin; Noh, Junyong (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Computer graphics is one of the most efficient ways to create a stereoscopic image. The process of stereoscopic CG generation is, however, still very inefficient compared to that of monoscopic CG generation. Despite that ...
  • RepSnapping: Efficient Image Cutout for Repeated Scene Elements 

    Huang, Hua; Zhang, Lei; Zhang, Hong-Chao (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Repeated scene elements are copious and ubiquitous in natural images. Cutout of those repeated elements usually involves tedious and laborious user interaction by previous image segmentation methods. In this paper, we ...
  • Video Brush: A Novel Interface for Efficient Video Cutout 

    Tong, Ruo-Feng; Zhang, Yun; Ding, Meng (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    We present Video Brush, a novel interface for interactive video cutout. Inspired by the progressive selection scheme in images, our interface is designed to select video objects by painting on successive frames as the video ...
  • Real Time Edit Propagation by Efficient Sampling 

    Bie, Xiaohui; Huang, Haoda; Wang, Wencheng (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    It is popular to edit the appearance of images using strokes, owing to their ease of use and convenience of conveying the user's intention. However, propagating the user inputs to the rest of the images requires solving ...
  • River Networks for Instant Procedural Planets 

    Derzapf, Evgenij; Ganster, Björn; Guthe, Michael; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Realistic terrain models are required in many applications, especially in computer games. Commonly, procedural models are applied to generate the corresponding models and let users experience a wide variety of new environments. ...
  • Authoring Hierarchical Road Networks 

    Galin, Eric; Peytavie, Adrien; Guérin, Eric; Benes, Bedrich (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    We present a procedural method for generating hierarchical road networks connecting cities, towns and villages over large terrains. Our approach relies on an original geometric graph generation algorithm based on a non- ...
  • Bipartite Polar Classification for Surface Reconstruction 

    Chen, Yi-Ling; Lee, Tung-Ying; Chen, Bing-Yu; Lai, Shang-Hong (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    In this paper, we propose bipartite polar classification to augment an input unorganized point set P with two disjoint groups of points distributed around the ambient space of P to assist the task of surface reconstruction. ...
  • Discriminative Sketch-based 3D Model Retrieval via Robust Shape Matching 

    Shao, Tianjia; Xu, Weiwei; Yin, Kangkang; Wang, Jingdong; Zhou, Kun; Guo, Baining (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    We propose a sketch-based 3D shape retrieval system that is substantially more discriminative and robust than existing systems, especially for complex models. The power of our system comes from a combination of a contourbased ...
  • SSD: Smooth Signed Distance Surface Reconstruction 

    Calakli, Fatih; Taubin, Gabriel (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    We introduce a new variational formulation for the problem of reconstructing a watertight surface defined by an implicit equation, from a finite set of oriented points; a problem which has attracted a lot of attention for ...
  • Asynchronous Evolution for Fully-Implicit and Semi-Implicit Time Integration 

    Schroeder, Craig; Kwatra, Nipun; Zheng, Wen; Fedkiw, Ron (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    We propose a series of techniques for hybridizing implicit and semi-implicit time integration methods in a manner that retains much of the speed of the implicit method without sacrificing all of the higher quality vibrations ...
  • Creating Fluid Animation from a Single Image using Video Database 

    Okabe, Makoto; Anjyo, Ken; Onai, Rikio (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    We present a method for synthesizing fluid animation from a single image, using a fluid video database. The user inputs a target painting or photograph of a fluid scene along with its alpha matte that extracts the fluid ...
  • Flexible Splicing of Upper-Body Motion Spaces on Locomotion 

    Basten, Ben J. H. van; Egges, Arjan (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    This paper presents an efficient technique for synthesizing motions by stitching, or splicing, an upper-body motion retrieved from a motion space on top of an existing lower-body locomotion of another motion. Compared to ...
  • Motion Retrieval Using Low-Rank Subspace Decomposition of Motion Volume 

    Sun, Chuan; Junejo, Imran; Foroosh, Hassan (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    This paper proposes a novel framework that allows for a flexible and an efficient retrieval of motion capture data in huge databases. The method first converts an action sequence into a novel representation, i.e. the ...
  • An Illustrative Visualization Framework for 3D Vector Fields 

    Chen, Cheng-Kai; Yan, Shi; Yu, Hongfeng; Max, Nelson; Ma, Kwan-Liu (The Eurographics Association and Blackwell Publishing Ltd., 2011)
    Most 3D vector field visualization techniques suffer from the problem of visual clutter, and it remains a challenging task to effectively convey both directional and structural information of 3D vector fields. In this ...
