    • Adding Depth to Cartoons Using Sparse Depth (In)equalities 

      Sykora, D.; Sedlacek, D.; Jinchao, S.; Dingliana, J.; Collins, S. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This paper presents a novel interactive approach for adding depth information into hand-drawn cartoon images and animations. In comparison to previous depth assignment techniques our solution requires minimal user effort ...

    • Printed Patterns for Enhanced Shape Perception of Papercraft Models 

      Xue, Su; Chen, Xuejin; Dorsey, Julie; Rushmeier, Holly (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Papercraft models can serve as inexpensive prototypes in shape design applications. However, in making the models some geometric detail is necessarily lost, and artificial creases may be visible, thereby limiting the utility ...

    • BetweenIT: An Interactive Tool for Tight Inbetweening 

      Whited, Brian; Noris, Gioacchino; Simmons, Maryann; Sumner, Robert W.; Gross, Markus; Rossignac, Jarek (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      The generation of inbetween frames that interpolate a given set of key frames is a major component in the production of a 2D feature animation. Our objective is to considerably reduce the cost of the inbetweening phase by ...

    • The Virtual Director: a Correlation-Based Online Viewing of Human Motion 

      Assa, J.; Wolf, L.; Cohen-Or, D. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Automatic camera control for scenes depicting human motion is an imperative topic in motion capture base animation, computer games, and other animation based fields. This challenging control problem is complex and combines ...

    • Articulated Billboards for Video-based Rendering 

      Germann, Marcel; Hornung, Alexander; Keiser, Richard; Ziegler, Remo; Wuermlin, Stephan; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a novel representation and rendering method for free-viewpoint video of human characters based on multiple input video streams. The basic idea is to approximate the articulated 3D shape of the human body using ...

    • Shared Sampling for Real-Time Alpha Matting 

      Gastal, Eduardo S. L.; Oliveira, Manuel M. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Image matting aims at extracting foreground elements from an image by means of color and opacity (alpha) estimation. While a lot of progress has been made in recent years on improving the accuracy of matting techniques, ...

    • Bidirectional Search for Interactive Motion Synthesis 

      Lo, Wan-Yen; Zwicker, Matthias (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present an approach to improve the search efficiency for near-optimal motion synthesis using motion graphs. An optimal or near-optimal path through a motion graph often leads to the most intuitive result. However, finding ...

    • Human Motion Synthesis with Optimization-based Graphs 

      Ren, Cheng; Zhao, Liming; Safonova, Alla (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Continuous constrained optimization is a powerful tool for synthesizing novel human motion segments that are short. Graph-based motion synthesis methods such as motion graphs and move trees are popular ways to synthesize ...

    • Synthesis of Responsive Motion Using a Dynamic Model 

      Ye, Yuting; Liu, C. Karen (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Synthesizing the movements of a responsive virtual character in the event of unexpected perturbations has proven a difficult challenge. To solve this problem, we devise a fully automatic method that learns a nonlinear ...

    • A Data-driven Segmentation for the Shoulder Complex 

      Hong, Q Youn; Park, Sang Il; Hodgins, Jessica K. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      The human shoulder complex is perhaps the most complicated joint in the human body being comprised of a set of three bones, muscles, tendons, and ligaments. Despite this anatomical complexity, computer graphics models for ...

    • Mesh Decomposition with Cross-Boundary Brushes 

      Zheng, Youyi; Tai, Chiew-Lan (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a new intuitive UI, which we call cross-boundary brushes, for interactive mesh decomposition. The user roughly draws one or more strokes across a desired cut and our system automatically returns a best cut running ...

    • Mesh Snapping: Robust Interactive Mesh Cutting Using Fast Geodesic Curvature Flow 

      Zhang, Juyong; Wu, Chunlin; Cai, Jianfei; Zheng, Jianmin; Tai, Xue-cheng (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      This paper considers the problem of interactively finding the cutting contour to extract components from a given mesh. Some existing methods support cuts of arbitrary shape but require careful and tedious input from the ...

    • Rendering Wave Effects with Augmented Light Field 

      Oh, Se Baek; Kashyap, Sriram; Garg, Rohit; Chandran, Sharat; Raskar, Ramesh (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Ray-based representations can model complex light transport but are limited in modeling diffraction effects that require the simulation of wavefront propagation. This paper provides a new paradigm that has the simplicity ...

    • Real-time Rendering of Heterogeneous Translucent Objects with Arbitrary Shapes 

      Wang, Yajun; Wang, Jiaping; Holzschuch, Nicolas; Subr, Kartic; Yong, Jun-Hai; Guo, Baining (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a real-time algorithm for rendering translucent objects of arbitrary shapes. We approximate the scattering of light inside the objects using the diffusion equation, which we solve on-the-fly using the GPU. Our ...

    • Real-time Realistic Ocean Lighting using Seamless Transitions from Geometry to BRDF 

      Bruneton, Eric; Neyret, Fabrice; Holzschuch, Nicolas (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Realistic animation and rendering of the ocean is an important aspect for simulators, movies and video games. By nature, the ocean is a difficult problem for Computer Graphics: it is a dynamic system, it combines wave ...

    • Optimizing Photo Composition 

      Liu, Ligang; Chen, Renjie; Wolf, Lior; Cohen-Or, Daniel (The Eurographics Association and Blackwell Publishing Ltd, 2010)
