A Biorthogonal Wavelet Approach based on Dual Subdivision
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper a biorthogonal wavelet approach based on Doo-Sabin subdivision is presented. In the dual subdivision like Doo-Sabin scheme, all the old control vertices disappear after one subdivision step, which is a big ... -
Capturing Intention-based Full-Frame Video Stabilization
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Annoying shaky motion is one of the significant problems in home videos, since hand shake is an unavoidable effect when capturing by using a hand-held camcorder. Video stabilization is an important technique to solve this ... -
Caustic Forecasting: Unbiased Estimation of Caustic Lighting for Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present an unbiased method for generating caustic lighting using importance sampled Path Tracing with Caustic Forecasting. Our technique is part of a straightforward rendering scheme which extends the Illumination by ... -
Context Aware Terrain Visualization for Wayfinding and Navigation
(The Eurographics Association and Blackwell Publishing Ltd, 2008)To assist wayfinding and navigation, the display of maps and driving directions on mobile devices is nowadays commonplace. While existing system can naturally exploit GPS information to facilitate orientation, the inherently ... -
The Craniofacial Reconstruction from the Local Structural Diversity of Skulls
(The Eurographics Association and Blackwell Publishing Ltd, 2008)The craniofacial reconstruction is employed as an initialization of the identification from skulls in forensics. In this paper, we present a two-level craniofacial reconstruction framework based on the local structural ... -
Distortion Optimization based Image Completion from a Large Displacement View
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a new image completion method based on an additional large displacement view (LDV) of the same scene for faithfully repairing large missing regions on the target image in an automatic way. A coarse-to-fine ... -
Example-based Multiple Local Color Transfer by Strokes
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper investigates a new approach for color transfer. Rather than transferring color from one image to another globally, we propose a system with a stroke-based user interface to provide a direct indication mechanism. ... -
Gradient-based Interpolation and Sampling for Real-time Rendering of Inhomogeneous, Single-scattering Media
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a real-time rendering algorithm for inhomogeneous, single scattering media, where all-frequency shading effects such as glows, light shafts, and volumetric shadows can all be captured. The algorithm first computes ... -
A Hidden-picture Puzzles Generator
(The Eurographics Association and Blackwell Publishing Ltd, 2008)A hidden-picture puzzle contains objects hidden in a background image, in such a way that each object fits closely into a local region of the background. Our system converts image of the background and objects into line ... -
Interactive Global Illumination for Deformable Geometry in CUDA
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Interactive global illumination for fully deformable scenes with dynamic relighting is currently a very elusive goal in the area of realistic rendering. In this work we propose a system that is based on explicit visibility ... -
Interactive Glossy Reflections using GPU-based Ray Tracing with Adaptive LOD
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present an interactive GPU-based algorithm for accurately rendering high-quality, dynamic glossy reflection effects from both HDR environment maps and local scene objects. Our method uses hardware rasterization to produce ... -
Interpolatory and Mixed Loop Schemes
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper presents a new interpolatory Loop scheme and an unified and mixed interpolatory and approximation subdivision scheme for triangular meshes. The former which is C1 continuous as same as the modified Butterfly ... -
Knitting a 3D Model
(The Eurographics Association and Blackwell Publishing Ltd, 2008)A knitted animal is made of a closed surface consisting of several knitted patches knitted out of yarn and stuffed with cotton (Fig. 1). We introduce a system to create a knitting pattern from a given 3D surface model ... -
Local Volume Preservation for Skinned Characters
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Generating plausible deformations of a character skin within the standard production pipeline is a challenge. This paper presents a volume preservation method dedicated to skinned characters. As usual, the character is ... -
Online Personalised Non-photorealistic Rendering Technique for 3D Geometry from Incremental Sketching
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper presents an online personalised non-photorealistic rendering (NPR) technique for 3D models generated from interactively sketched input. This technique has been integrated into a sketch-based modelling system. ... -
Part-type Segmentation of Articulated Voxel-Shapes using the Junction Rule
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a part-type segmentation method for articulated voxel-shapes based on curve skeletons. Shapes are considered to consist of several simpler, intersecting shapes. Our method is based on the junction rule: the ... -
Patch-type Segmentation of Voxel Shapes using Simplified Surface Skeletons
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a new method for decomposing a 3D voxel shape into disjoint segments using the shape s simplified surface-skeleton. The surface skeleton of a shape consists of 2D manifolds inside its volume. Each skeleton point ... -
Perceptual Evaluation of Color-to-Grayscale Image Conversions
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Color images often have to be converted to grayscale for reproduction, artistic purposes, or for subsequent processing. Methods performing the conversion of color images to grayscale aim to retain as much information about ... -
Photon-driven Irradiance Cache
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We describe a global illumination method combining two well known techniques: photon mapping and irradiance caching. The photon mapping method has the advantage of being view independent but requires a costly additional ...
