    • Optimizing Photo Composition 

      Liu, Ligang; Chen, Renjie; Wolf, Lior; Cohen-Or, Daniel (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Aesthetic images evoke an emotional response that transcends mere visual appreciation. In this work we develop a novel computational means for evaluating the composition aesthetics of a given image based on measuring several ...

    • Perceptually-motivated Real-time Temporal Upsampling of 3D Content for High-refresh-rate Displays 

      Didyk, Piotr; Eisemann, Elmar; Ritschel, Tobias; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      High-refresh-rate displays (e. g., 120 Hz) have recently become available on the consumer market and quickly gain on popularity. One of their aims is to reduce the perceived blur created by moving objects that are tracked ...

    • Practical quad mesh simplification 

      Tarini, Marco; Pietroni, Nico; Cignoni, Paolo; Panozzo, Daniele; Puppo, Enrico (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In this paper we present an innovative approach to incremental quad mesh simplification, i.e. the task of producing a low complexity quad mesh starting from a high complexity one. The process is based on a novel set of ...

    • 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 ...

    • Procedural Generation of Roads 

      Galin, E.; Peytavie, A.; Marechal, N.; Guerin, E. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      In this paper, we propose an automatic method for generating roads based on a weighted anisotropic shortest path algorithm. Given an input scene, we automatically create a path connecting an initial and a final point. The ...

    • Puzzle-like Collage 

      Goferman, Stas; Tal, Ayellet; Zelnik-Manor, Lihi (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Collages have been a common form of artistic expression since their first appearance in China around 200 BC. Recently, with the advance of digital cameras and digital image editing tools, collages have gained popularity ...

    • 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 ...

    • 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 ...

    • Reinterpretable Imager: Towards Variable Post-Capture Space, Angle and Time Resolution in Photography 

      Agrawal, Amit; Veeraraghavan, Ashok; Raskar, Ramesh (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We describe a novel multiplexing approach to achieve tradeoffs in space, angle and time resolution in photography. We explore the problem of mapping useful subsets of time-varying 4D lightfields in a single snapshot. Our ...

    • 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 ...

    • Scalable Height Field Self-Shadowing 

      Timonen, Ville; Westerholm, Jan (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a new method suitable for general purpose graphics processing units to render self-shadows on dynamic height fields under dynamic light environments in real-time. Visibility for each point in the height field ...

    • Seamless Montage for Texturing Models 

      Gal, Ran; Wexler, Yonatan; Ofek, Eyal; Hoppe, Hugues; Cohen-Or, Daniel (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present an automatic method to recover high-resolution texture over an object by mapping detailed photographs onto its surface. Such high-resolution detail often reveals inaccuracies in geometry and registration, as ...

    • 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, ...

    • Sketching Clothoid Splines Using Shortest Paths 

      Baran, Ilya; Lehtinen, Jaakko; Popovic, Jovan (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Clothoid splines are gaining popularity as a curve representation due to their intrinsically pleasing curvature, which varies piecewise linearly over arc length. However, constructing them from hand-drawn strokes remains ...

    • SoundRiver: Semantically-Rich Sound Illustration 

      Jaenicke, H.; Borgo, R.; Mason, J. S. D.; Chen, M. (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Sound is an integral part of most movies and videos. In many situations, viewers of a video are unable to hear the sound track, for example, when watching it in a fast forward mode, viewing it by hearing-impaired viewers ...

    • 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 ...

    • Tetrahedral Embedded Boundary Methods for Accurate and Flexible Adaptive Fluids 

      Batty, Christopher; Xenos, Stefan; Houston, Ben (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      When simulating fluids, tetrahedral methods provide flexibility and ease of adaptivity that Cartesian grids find difficult to match. However, this approach has so far been limited by two conflicting requirements. First, ...

    • TouchTone: Interactive Local Image Adjustment Using Point-and-Swipe 

      Liang, Chia-Kai; Chen, Wei-Chao; Gelfand, Natasha (The Eurographics Association and Blackwell Publishing Ltd, 2010)
