    • Incomplete 3D Shape Retrieval via Sparse Dictionary Learning 

      Wan, Lili; Jiang, Jingyu; Zhang, Hao (The Eurographics Association, 2015)
      How to deal with missing data is one of the recurring questions in data analysis. The handling of significant missing data is a challenge. In this paper, we are interested in the problem of 3D shape retrieval where the ...

    • Complex Modulation Computer-Generated Hologram with Occlusion Effect by a Fast Hybrid Point-source/Wave-field Approach 

      Gilles, Antonin; Gioia, Patrick; Cozot, Rémi; Morin, Luce (The Eurographics Association, 2015)
      We propose a fast Computer-Generated Hologram (CGH) computation method with occlusion effect based on a hybrid point-source/wave-field approach. Whereas previously proposed methods tried to reduce the computational complexity ...

    • Modal Space Subdivision for Physically-plausible 4D Shape Sequence Completion from Sparse Samples 

      Xia, Qing; Li, Shuai; Qin, Hong; Hao, Aimin (The Eurographics Association, 2015)
      Subdivision techniques are powerful and ubiquitous in generating smooth surfaces from coarse 3D polygonal models, yet space-time subdivision remains unexplored when the goal is to produce dense physically-realistic shape ...

    • Robust and GPU-friendly Isotropic Meshing Based on Narrow-banded Euclidean Distance Transformation 

      Leung, Yuen Shan; Wang, Xiaoning; He, Ying; Liu, Yong-Jin; Wang, Charlie C. L. (The Eurographics Association, 2015)
      In this paper, we propose a simple-yet-effective method for isotropic meshing via Euclidean distance transformation based Centroidal Voronoi Tessellation (CVT). The proposed approach aims at improving the performance as ...

    • Pairwise Surface Registration Using Local Voxelizer 

      Song, Peng; Chen, Xiaoping (The Eurographics Association, 2015)
      Surface registration is the process that brings scans into a common coordinate system by aligning their overlapping components, which can be achieved by finding a few pairs of matched points on each scan pair using shape ...

    • Frontmatter: Pacific Graphics 2015 - Short Papers 

      Stam, Jos; Mitra, Niloy J.; Xu, Kun (The Eurographics Association, 2015)

    • Sky Browser: Search for HDR Sky Maps 

      Chalmers, Andrew; Lewis, John; Hillman, Peter; Tait, Charlie; Rhee, Taehyun (The Eurographics Association, 2014)
      In a visual effects studio for movie production, sky maps play an important role for acting as a sky backdrop to a scene. The backdrop to a scene is often represented using a high-resolution sky map. This motivates the ...

    • A Simple Artistic Rendering Method for Stereoscopic Images 

      Li, Dajin; Bai, Chengjie (The Eurographics Association, 2014)
      General painterly rendering algorithms cannot be used to render stereo image pair separately because they may produce random noise and lead to inconsistency between binocular images. In this paper, a generic rendering ...

    • Perceptually Optimised Illumination for Seamless Composites 

      Chalmers, Andrew; Choi, Jong Jin; Rhee, Taehyun (The Eurographics Association, 2014)
      Realistic illumination in composition is important for a seamless mixture between the virtual and real world objects in visual effects and mixed reality. The seamlessness is the measure of how perceivably apparent the ...

    • Automatic 3D Posing from 2D Hand-Drawn Sketches 

      Gouvatsos, Alexandros; Xiao, Zhidong; Marsden, Neil; Zhang, Jian J. (The Eurographics Association, 2014)
      Inferring the 3D pose of a character from a drawing is a non-trivial and under-constrained problem. Solving it may help automate various parts of an animation production pipeline such as pre-visualisation. In this paper, ...

    • Parallel BTF Compression with Multi-Level Vector Quantization in OpenCL 

      Egert, Petr; Vlastimil, Havran (The Eurographics Association, 2014)
      Bidirectional Texture Function (BTF) as an effective visual fidelity representation of surface appearance is becoming more and more widely used. In this paper we report on contributions to BTF data compression for multi-level ...

    • Visual Analysis of FPS Gameplay Data: From Game Design to Player Behavior 

      Li, Quan; Qu, Huamin (The Eurographics Association, 2014)
      Gameplay data analysis has already become an important method for analyzing player behavior in games. Visualization is a promising way to explore and gain insight into the data. In this paper, we work closely with the game ...

    • Extraction and Transfer of Facial Expression Wrinkles for Facial Performance Enhancement 

      Shin, Il-Kyu; Öztireli, A. Cengiz; Kim, Hyeon-Joong; Beeler, Thabo; Gross, Markus; Choi, Soo-Mi (The Eurographics Association, 2014)
      Creating realistic models and animations of human faces with adequate level of detail is very challenging due to the high complexity of facial deformations and the sensitivity of the human visual system to human faces. One ...

    • PatchMove: Patch-based Fast Image Interpolation with Greedy Bidirectional Correspondence 

      Saito, Shunsuke; Sakamoto, Ryuuki; Morishima, Shigeo (The Eurographics Association, 2014)
      In this paper, we present a method for the plausible interpolation of images. This method has several applications, such as for smooth view interpolation, low frame-rate video upsampling, and animation. The central idea ...

    • Example-based Haze Removal with two-layer Gaussian Process Regressions 

      Fan, Xin; Gao, Renjie; Wang, Yi (The Eurographics Association, 2014)
      Hazy images suffer from low visibility and contrast. Researchers have devoted great efforts to haze removal with the prior assumptions on observations in the past decade. However, these priors from observations can provide ...

    • Geometry-Aware Image Completion via Multiple Examples 

      Wang, Guihang; Chen, Xuejin; Hu, Siyu (The Eurographics Association, 2014)
      When browsing through photographs taken during a trip, it can be a distressing discovery to find many other bystanders captured within the frame. A visually compelling snapshot preserves the desired subject in the foreground, ...
