    • 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 ...

    • 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, ...

    • Image Palette: Brushstroke Synthesis-based Style Transfer 

      Miao, Zheng; Zhang, Yan; Zheng, Zhibin; Sun, Zhengxing (The Eurographics Association, 2014)
      Painting style transfer is one kind technology where given the sample images with some specific art style, we can render the target images in the same style as the samples after some computation. In this paper we present ...

    • Automatic Aesthetics-based Lighting Design with Global Illumination 

      Léon, Vincent; Gruson, Adrien; Cozot, Rémi; Bouatouch, Kadi (The Eurographics Association, 2014)
      In computer graphics, lighting plays an important role in the appearance of a scene. A change in the configuration of light sources can lead to different aesthetics in the final rendered image. Lighting design becomes ...

    • 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 ...

    • Data-Driven Fire Synthesis and Design 

      Wong, Sai-Keung; Chang, Tse-Ching; Ho, Tan-Chi; Chuang, Jung-Hong (The Eurographics Association, 2014)
      We present a data-driven synthesis approach to design and animate fires in desired shapes and motions. At the preprocessing stage, our system simulates a set of basis fires under specific simulation configurations and ...

    • 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 ...

    • 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 ...

    • Quantitative Analysis of Voxel Raytracing Acceleration Structures 

      Chajdas, Matthäus G.; Westermann, Rüdiger (The Eurographics Association, 2014)
      In this work, we provide a comprehensive analysis of GPU acceleration structures for voxel raytracing. We compare the commonly used octrees to BVH and KD trees, which are the standard in GPU triangle raytracing. Evaluating ...

    • 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, ...
