Affective Modelling: Profiling Geometrical Models with Human Emotional Responses
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper, a novel concept, Affective Modelling, is introduced to encapsulate the idea of creating 3D models based on the emotional responses that they may invoke. Research on perceptually-related issues in Computer ... -
Approximate on-Surface Distance Computation using Quasi-Developable Charts
(The Eurographics Association and Blackwell Publishing Ltd, 2009)There is a vast number of applications that require distance field computation over triangular meshes. State-of-the-art algorithms have quadratic or sub-quadratic worst-case complexity, making them impractical for interactive ... -
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 ... -
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 ... -
The Dual-microfacet Model for Capturing Thin Transparent Slabs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a new model, called the dual-microfacet, for those materials such as paper and plastic formed by a thin, transparent slab lying between two surfaces of spatially varying roughness. Light transmission through the ... -
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 ... -
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 ... -
Fast, Sub-pixel Antialiased Shadow Maps
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Solving aliasing artifacts is an essential problem in shadow mapping approaches. Many works have been proposed, however, most of them focused on removing the texel-level aliasing that results from the limited resolution ... -
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 ... -
Frontmatter and Cover
(The Eurographics Association and Blackwell Publishing Ltd, 2009) -
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. ... -
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. ... -
HPCCD: Hybrid Parallel Continuous Collision Detection using CPUs and GPUs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a novel, hybrid parallel continuous collision detection (HPCCD) method that exploits the availability of multi-core CPU and GPU architectures. HPCCD is based on a bounding volume hierarchy (BVH) and selectively ... -
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, ... -
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 ... -
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 ... -
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 ... -
An Intuitive Interface for Interactive High Quality Image-Based Modeling
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present the design of an interactive image-based modeling tool that enables a user to quickly generate detailed 3D models with texture from a set of calibrated input images. Our main contribution is an intuitive user ... -
Linkless Octree Using Multi-Level Perfect Hashing
(The Eurographics Association and Blackwell Publishing Ltd, 2009)The standard C/C++ implementation of a spatial partitioning data structure, such as octree and quadtree, is often inefficient in terms of storage requirements particularly when the memory overhead for maintaining parent-to-child ... -
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 ...
