Analytic Curve Skeletons for 3D Surface Modeling and Processing
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a new curve skeleton model designed for surface modeling and processing. This skeleton is defined as the geometrical integration of a piecewise harmonic parameterization defined over a disk-cylinder surface ... -
Video Panorama for 2D to 3D Conversion
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Accurate depth estimation is a challenging, yet essential step in the conversion of a 2D image sequence to a 3D stereo sequence. We present a novel approach to construct a temporally coherent depth map for each image in a ... -
Digital Camouflage Images Using Two-scale Decomposition
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present an alternative approach to create digital camouflage images which follows human's perception intuition and complies with the physical creation procedure of artists. Our method is based on a two-scale decomposition ... -
Improving Photo Composition Elegantly: Considering Image Similarity During Composition
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Optimization of images with bad compositions has attracted increasing attention in recent years. Previous methods however seldomly consider image similarity when improving composition aesthetics. This may lead to significant ... -
Registration Based Non-uniform Motion Deblurring
(The Eurographics Association and Blackwell Publishing Ltd., 2012)This paper proposes an algorithm which uses image registration to estimate a non-uniform motion blur point spread function (PSF) caused by camera shake. Our study is based on a motion blur model which models blur effects ... -
Hierarchical Narrative Collage For Digital Photo Album
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Collage can provide a summary form on the collection of photos in an album. In this paper, we introduce a novel approach to constructing photo collage in the hierarchical narrative manner. As opposed to previous methods ... -
Homunculus Warping: Conveying Importance Using Self-intersection-free Non-homogeneous Mesh Deformation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Size matters. Human perception most naturally relates relative extent, area or volume to importance, nearness and weight. Reversely, conveying importance of something by depicting it at a different size is a classic artistic ... -
Approximate Bias Compensation for Rendering Scenes with Heterogeneous Participating Media
(The Eurographics Association and Blackwell Publishing Ltd., 2012)In this paper we present a novel method for high-quality rendering of scenes with participating media. Our technique is based on instant radiosity, which is used to approximate indirect illumination between surfaces by ... -
Adaptive Cross-sections of Anatomical Models
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Medical illustrations have been used for a long time for teaching and communicating information for diagnosis or surgery planning. Illustrative visualization systems create methods and tools that adapt traditional illustration ... -
Multi-Layered Automultiscopic Displays
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Our hybrid display model combines multiple automultiscopic elements volumetrically to support horizontal and vertical parallax at a larger depth of field and better accommodation cues compared to single layer elements. In ... -
Multi-scale Assemblage for Procedural Texturing
(The Eurographics Association and Blackwell Publishing Ltd., 2012)A procedural pattern generation process, called multi-scale ''assemblage'' is introduced. An assemblage is defined as a multi-scale composition of ''multi-variate'' statistical figures, that can be kernel functions for ... -
Improving the Parameterization of Approximate Subdivision Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We provide a method for improving the parameterization of patching schemes that approximate Catmull-Clark subdivision surfaces, such that the new parameterization conforms better to that of the original subdivision surface. ... -
Texture Compression using Wavelet Decomposition
(The Eurographics Association and Blackwell Publishing Ltd., 2012)In this paper we introduce a new fixed-rate texture compression scheme based on the energy compaction properties of a modified Haar transform. The coefficients of this transform are quantized and stored using standard block ... -
A Global Parity Measure for Incomplete Point Cloud Data
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Shapes with complex geometric and topological features such as tunnels, neighboring sheets, and cavities are susceptible to undersampling and continue to challenge existing reconstruction techniques. In this work we introduce ... -
GPU Shape Grammars
(The Eurographics Association and Blackwell Publishing Ltd., 2012)GPU Shape Grammars provide a solution for interactive procedural generation, tuning and visualization of massive environment elements for both video games and production rendering. Our technique generates detailed models ... -
SD Models: Super-Deformed Character Models
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Super-deformed, SD, is a specific artistic style for Japanese manga and anime which exaggerates characters in the goal of appearing cute and funny. The SD style characters are widely used, and can be seen in many anime, ... -
Isotropic Surface Remeshing Using Constrained Centroidal Delaunay Mesh
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We develop a novel isotropic remeshing method based on constrained centroidal Delaunay mesh (CCDM), a generalization of centroidal patch triangulation from 2D to mesh surface. Our method starts with resampling an input ... -
Retrieval and Visualization of Human Motion Data via Stick Figures
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We propose 2D stick figures as a unified medium for visualizing and searching for human motion data. The stick figures can express a wide range or human motion, and they are easy to be drawn by people without any professional ... -
Two-Finger Gestures for 6DOF Manipulation of 3D Objects
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Multitouch input devices afford effective solutions for 6DOF (six Degrees of Freedom) manipulation of 3D objects. Mainly focusing on large-size multitouch screens, existing solutions typically require at least three fingers ... -
Realtime Two-Way Coupling of Meshless Fluids and Nonlinear FEM
(The Eurographics Association and Blackwell Publishing Ltd., 2012)In this paper, we present a novel method to couple Smoothed Particle Hydrodynamics (SPH) and nonlinear FEM to animate the interaction of fluids and deformable solids in real time. To accurately model the coupling, we ...
