    • Structure-Preserving Image Smoothing via Phase Congruency-aware Weighted Least Square 

      Yu, Jinze; Sato, Yoichi (The Eurographics Association, 2015)
      Structure-preserving image smoothing, or also understood as structure-texture separation problem, is an important topic for both computer vision and computer graphics as structure-texture separation can help better image ...

    • Parallel Importing of OBJ Meshes in CUDA 

      Possemiers, Aidan. L.; Lee, Ickjai (The Eurographics Association, 2015)
      Alias | Wavefront OBJ meshes are a common text file type for transferring 3D mesh data between applications made by different vendors. However, as the mesh complexity gets higher and denser, the files become larger and ...

    • Accelerating Graph-based Path Planning Through Waypoint Clustering 

      Wardhana, Nicholas Mario; Johan, Henry; Seah, Hock-Soon (The Eurographics Association, 2015)
      Modern Computer Graphics applications commonly feature very large virtual environments and diverse characters which perform different kinds of motions. To accelerate path planning in such scenario, we propose subregion ...

    • 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 ...

    • 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 ...

    • A Voronoi based Labeling Approach to Curve Reconstruction and Medial Axis Approximation 

      Peethambaran, Jiju; Parakkat, Amal Dev; Muthuganapathy, Ramanathan (The Eurographics Association, 2015)
      In this paper, we present a Voronoi based algorithm for closed curve reconstruction and medial axis approximation from planar points. In principle, the algorithm estimates one of the poles (farthest Voronoi vertices of a ...

    • Efficient Interactive Image Segmentation with Local and Global Consistency 

      Li, Hong; Wu, Wen; Wu, Enhua (The Eurographics Association, 2015)
      Interactive image segmentation models aim to classify the image pixels into foreground and background classes given some foreground and background scribbles. In this paper, we propose a novel framework for interactive image ...

    • Superpixels Generation of RGB-D Images Based on Geodesic Distance 

      Pan, Xiao; Zhou, Yuanfeng; Liu, Shuwei; Zhang, Caiming (The Eurographics Association, 2015)
      A novel algorithm for generating superpixels of RGB-D images is presented in this paper. A regular triangular mesh is constructed by the depth and a local geometric features sensitive initialization method is proposed for ...

    • Adaptive Hierarchical Shape Matching 

      Tian, Yuan; Yang, Yin; Guo, Xiaohu; Prabhakaran, Balakrishnan (The Eurographics Association, 2015)
      In this paper, we present an adaptive hierarchical method allowing users to interact with geometrically complex 3D deformable objects based on an extended shape matching approach. Our method extends the existing multiresolution ...

    • Frontmatter: Pacific Graphics 2015 - Short Papers 

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

    • 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 ...

    • Simultaneous Stereo Rectification and Distortion Correction with Application to DoF Synthesis 

      Yeh, Chen Ting; Ho, Tien-Yu; Huang, Szu-Hao; Lai, Shang-Hong (The Eurographics Association, 2015)
      Stereo rectification based on epipolar geometry is an image transformation process which is used to align the rectified stereo images to be coplanar. For image pairs captured by low-cost stereo camera systems, image noises ...

    • 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 ...
