Generalized Discrete Ricci Flow
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Surface Ricci flow is a powerful tool to design Riemannian metrics by user defined curvatures. Discrete surface Ricci flow has been broadly applied for surface parameterization, shape analysis, and computational topology. ... -
Mesh Segmentation Refinement
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This paper proposes a method for refining existing mesh segmentations, employing a novel extension of the active contour approach to meshes. Given a segmentation, produced either by an automatic segmentation method or ... -
Curvature Aware Fundamental Cycles
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a graph algorithm to find fundamental cycles aligned with the principal curvature directions of a surface. Specifically, we use the tree-cotree decomposition of graphs embedded in manifolds, guided with edge ... -
SecondSkin: An interactive method for appearance transfer
(The Eurographics Association and Blackwell Publishing Ltd, 2009)SecondSkin estimates an appearance model for an object visible in a video sequence, without the need for complex interaction or any calibration apparatus. This model can then be transferred to other objects, allowing a ... -
Frontmatter and Cover

Expression Synthesis and Transfer in Parameter Spaces
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper, we introduce a novel framework that allows users to synthesize the expression of a 3D character by providing a intuitive set of parametric controls. Assuming that human face movements are formed by a set of ... -
Simulation of Tearing Cloth with Frayed Edges
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Woven cloth can commonly be seen in daily life and also in animation. Unless prevented in some way, woven cloth usually frays at the edges. However, in computer graphics, woven cloth is typically modeled as a continuum ... -
Simulating Gaseous Fluids with Low and High Speeds
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Gaseous fluids may move slowly, as smoke does, or at high speed, such as occurs with explosions. High-speed gas flow is always accompanied by low-speed gas flow, which produces rich visual details in the fluid motion. ... -
Procedural Generation of Rock Piles using Aperiodic Tiling
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper, we present a tiling method for generating piles of rocks without any computationally demanding physically-based simulation. Previous techniques rely on a periodic tiling of rocks and generate unrealistic ... -
Gradient-Preserving Color Transfer
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Color transfer is an image processing technique which can produce a new image combining one source image s contents with another image s color style. While being able to produce convincing results, however, Reinhard et al. ... -
Procedural Synthesis using Vortex Particle Method for Fluid Simulation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We propose a fast and effective technique to improve sub-grid visual details of the grid based fluid simulation. Our method procedurally synthesizes the flow fields coming from the incompressible Navier-Stokes solver and ... -
Automatic Correction of Saturated Regions in Photographs using Cross-Channel Correlation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Incorrectly setting the camera s exposure can have a significant negative effect on a photograph. Over-exposing photographs causes pixels to exhibit unpleasant artifacts due to saturation of the sensor. Saturation removal ... -
Edit Propagation on Bidirectional Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We propose an efficient method for editing bidirectional texture functions (BTFs) based on edit propagation scheme. In our approach, users specify sparse edits on a certain slice of BTF. An edit propagation scheme is then ... -
Live Video Montage with a Rotating Camera
(The Eurographics Association and Blackwell Publishing Ltd, 2009)High-quality video editing usually requires accurate layer separation in order to resolve occlusions. However, most of the existing bilayer segmentation algorithms require either considerable user intervention or a simple ... -
Interactive Rendering of Interior Scenes with Dynamic Environment Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2009)A rendering system for interior scenes is proposed in this paper. The light reaches the interior scene, usually through small regions, such as windows or abat-jours, which we call portals. To provide a solution, suitable ... -
Interactive Cover Design Considering Physical Constraints
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We developed an interactive system to design a customized cover for a given three-dimensional (3D) object such as a camera, teapot, or car. The system first computes the convex hull of the input geometry. The user segments ... -
Flow-Based Automatic Generation of Hybrid Picture Mazes
(The Eurographics Association and Blackwell Publishing Ltd, 2009)A method for automatically generating a picture maze from two different images is introduced throughout this paper. The process begins with the extraction of salient contours and edge tangent flow information from the ... -
Image and Video Abstraction by Anisotropic Kuwahara Filtering
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a non-photorealistic rendering technique to transform color images and videos into painterly abstractions. It is based on a generalization of the Kuwahara filter that is adapted to the local shape of features, ... -
Variational Surface Approximation and Model Selection
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We consider the problem of approximating an arbitrary generic surface with a given set of simple surface primitives. In contrast to previous approaches based on variational surface approximation, which are primarily concerned ... -
Image-to-Geometry Registration: a Mutual Information Method exploiting Illumination-related Geometric Properties
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This work concerns a novel study in the field of image-to-geometry registration. Our approach takes inspiration from medical imaging, in particular from multi-modal image registration. Most of the algorithms developed in ...
