Diffusion Tensor Weighted Harmonic Fields for Feature Classification
(The Eurographics Association, 2011)This paper presents an efficient method for feature definition and classification on shapes. We tackle this challenge by exploring the weighted harmonic field (WHF), which is also the stable state of a heat diffusion ... -
An Effective and Efficient Contour-based Corner Detector using Simple Triangular Theory
(The Eurographics Association, 2011)Corner detection is an important operation in many computer vision applications. Among the contour-based corner detectors in the literature, the Chord-to-Point Distance Accumulation (CPDA) detector is reported to have one ... -
Facial Retargeting by Adding Supplemental Blendshapes
(The Eurographics Association, 2011)This paper introduces a novel method to add a minimal set of missing blendshapes to automatically improve the quality of the retargeting result. Our approach compares the expression spaces defined by the source and the ... -
Fast Computing Adaptively Sampled Distance Field on GPU
(The Eurographics Association, 2011)In this paper we present an efficient method to compute the signed distance field for a large triangle mesh, which can run interactively with GPU accelerated. Restricted by absence of flexible pointer addressing on GPU, ... -
Fast Level Set Image Segmentation Using New Evolution Indicator Operators
(The Eurographics Association, 2011)We propose an effective level set evolution method for robust object segmentation in real images. We construct an effective region indicator and a multiscale edge indicator to adaptively guide the evolution of the level ... -
A Fast Simulation Method Using SPH and Wavelet for Sub-Particle-Scale Turbulent Flow
(The Eurographics Association, 2011)This paper presents a fast simulation method for turbulent flow which uses a particle method and wavelet analysis. To simulate fluid flow, the method uses smoothed particle hydrodynamics (SPH), which discretizes the fluid ... -
Feature Adaptive Surfel Set Simplification
(The Eurographics Association, 2011)In this paper we propose a novel scheme for simplifying a surfel set with the resultant surfels computed and distributed in an effort to preserve prominent geometric and textural features with a reduced number of primitives. ... -
Feature-Aware Mesh for Image Retargeting
(The Eurographics Association, 2011)Image retargeting adapts an input image to displays other than originally intended while minimizing visual distortion. Most warping-based methods formulate retargeting as a spatially-varying warping problem over a uniform ... -
Feature-Aware Reconstruction of Volume Data via Trivariate Splines
(The Eurographics Association, 2011)In this paper, we propose a novel approach that transforms discrete volumetric data directly acquired from scanning devices into continuous spline representation with tensor-product regular structure. Our method is achieved ... -
Illustrative Line Styles for Flow Visualization
(The Eurographics Association, 2011)We present a flexible illustrative line style model for the visualization of streamline data. Our model partitions vieworiented line strips into parallel bands whose basic visual properties can be controlled independently. ... -
An Image-based Hair Styling System Using Layered Texture Pieces
(The Eurographics Association, 2011)We present an interactive system that allows the user to finely edit a hairstyle image so that the image can be naturally synthesized onto a given facial image. In our system, a hairstyle is composed by stacking texture ... -
Interactive Design of Planar Curved Folding by Reflection
(The Eurographics Association, 2011)Designing curved folds of a developable surface remains an open problem. No analytical method for the design of curved folds has been reported. Although optimization methods exist, it is difficult to interactively design ... -
Perceptually-based Stroke Pattern Synthesis
(The Eurographics Association, 2011)We present a novel method to synthesize stroke patterns from a user-specified vector reference pattern. The main idea is inspired by research in visual perception. We first extract the features which have an important ... -
Real-time Realistic Voxel-based Rendering
(The Eurographics Association, 2011)With the advance of graphics hardware, setting 3D texture as render target is newly available to allow voxelization algorithms to record the existence, color and normal information in a voxel directly without specific ... -
Real-time Rendering of Endless Cloud Animation
(The Eurographics Association, 2011)In this paper, we propose a real-time animation method for dynamic clouds illuminated by sunlight and skylight with multiple scattering. In order to create animations of outdoor scenes, it is necessary to render time-varying ... -
Sketch-based Breaking Waves
(The Eurographics Association, 2011)We present a sketching method for animating breaking waves in this paper. Our approach allows an animator to control physically-based wave breaking effects by drawing the outline of the wave shape intuitively. To do this, ... -
Two Simple Single-pass GPU methods for Multi-channel Surface Voxelization of Dynamic Scenes
(The Eurographics Association, 2011)An increasing number of rendering and geometry processing algorithms relies on volume data to calculate anything from effects like smoke/fluid simulations, visibility information or global illumination effects. We present ... -
Virtual City Map Generation using Area Subdivision
(The Eurographics Association, 2011)In this paper we present a new approach to build typical street networks for urban and rural areas automatically. Most street networks have a characteristic appearance which is a mixture between a kind of a regular spreading ... -
Visualizing Local Weather Characteristics Interpreted from Glider GPS Flight Logs
(The Eurographics Association, 2011)Visualization can aid in improving the validation and evaluation of glider flight logs, which in turn can make the logs more meaningful in flight evaluation and planning. This paper presents techniques to interpret and ...
