Boundary-Aware Extinction Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We introduce Boundary-Aware Extinction Maps for interactive rendering of massive heterogeneous volumetric datasets. Our approach is based on the projection of the extinction along light rays into a boundary-aware function ... -
Coarse-to-Fine Normal Filtering for Feature-Preserving Mesh Denoising Based on Isotropic Subneighborhoods
(The Eurographics Association and Blackwell Publishing Ltd., 2013)State-of-the-art normal filters usually denoise each face normal using its entire anisotropic neighborhood. However, enforcing these filters indiscriminately on the anisotropic neighborhood will lead to feature blurring, ... -
Combustion Waves on the Point Set Surface
(The Eurographics Association and Blackwell Publishing Ltd., 2013)This paper introduces a combustion model of heat transfer and fuel consumption for the propagation of a fire front on a point cloud surface. The heat transfer includes the heat advection by the airflow as well as diffusion, ... -
Constrainable Multigrid for Cloth
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a new technique which can handle both point and sliding constraints in the multigrid (MG) framework. Although the MG method can theoretically perform as fast as O(N), the development of a clothing simulator based ... -
Dynamic Comics for Hierarchical Abstraction of 3D Animation Data
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Image storyboards of films and videos are useful for quick browsing and automatic video processing. A common approach for producing image storyboards is to display a set of selected key-frames in temporal order, which has ... -
An Efficient and Scalable Image Filtering Framework Using VIPS Fusion
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Edge-preserving image filtering is a valuable tool for a variety of applications in image processing and computer vision. Motivated by a new simple but effective local Laplacian filter, we propose a scalable and efficient ... -
Efficient Shadow Removal Using Subregion Matching Illumination Transfer
(The Eurographics Association and Blackwell Publishing Ltd., 2013)This paper proposes a new shadow removal approach for input single natural image by using subregion matching illumination transfer. We first propose an effective and automatic shadow detection algorithm incorporating global ... -
Efficient Smoke Simulation on Curvilinear Grids
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present an efficient approach for performing smoke simulation on curvilinear grids. Our technique is based on a fast unconditionally-stable advection algorithm and on a new and efficient solution to enforce mass ... -
EnvyDepth: An Interface for Recovering Local Natural Illumination from Environment Maps
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this paper, we present EnvyDepth, an interface for recovering local illumination from a single HDR environment map. In EnvyDepth, the user quickly indicates strokes to mark regions of the environment map that should be ... -
Evaluation of Tone Mapping Operators for HDR-Video
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Eleven tone-mapping operators intended for video processing are analyzed and evaluated with camera-captured and computer-generated high-dynamic-range content. After optimizing the parameters of the operators in a formal ... -
Eye-Centered Color Adaptation in Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Color adaptation is a well known ability of the human visual system (HVS). Colors are perceived as constant even though the illuminant color changes. Indeed, the perceived color of a diffuse white sheet of paper is still ... -
Fast Image-Based Modeling of Astronomical Nebulae
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Astronomical nebulae are among the most complex and visually appealing phenomena known outside the bounds of the Solar System. However, our fixed vantage point on Earth limits us to a single known view of these objects, ... -
Garment Modeling from a Single Image
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Modeling of realistic garments is essential for online shopping and many other applications including virtual characters. Most of existing methods either require a multi-camera capture setup or a restricted mannequin pose. ... -
A GPU-based Streaming Algorithm for High-Resolution Cloth Simulation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a GPU-based streaming algorithm to perform high-resolution and accurate cloth simulation. We map all the components of cloth simulation pipeline, including time integration, collision detection, collision response, ... -
Guided Real-Time Scanning of Indoor Objects
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Advances in 3D acquisition devices provide unprecedented opportunities for quickly scanning indoor environments. Such raw scans, however, are often noisy, incomplete, and significantly corrupted, making semantic scene ... -
Hair Interpolation for Portrait Morphing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this paper we study the problem of hair interpolation: given two 3D hair models, we want to generate a sequence of intermediate hair models that transform from one input to another both smoothly and aesthetically pleasing. ... -
Implicit Integration for Particle-based Simulation of Elasto-Plastic Solids
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a novel particle-based method for stable simulation of elasto-plastic materials. The main contribution of our method is an implicit numerical integrator, using a physically-based model, for computing particles ... -
Improving Memory Space Efficiency of Kd-tree for Real-time Ray Tracing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Compared with its competitors such as the bounding volume hierarchy, a drawback of the kd-tree structure is that a large number of triangles are repeatedly duplicated during its construction, which often leads to inefficient, ... -
Interactive Learning for Point-Cloud Motion Segmentation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Segmenting a moving foreground (fg) from its background (bg) is a fundamental step in many Machine Vision and Computer Graphics applications. Nevertheless, hardly any attempts have been made to tackle this problem in dynamic ... -
Interactive Physics-based Ink Splattering Art Creation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)This paper presents an interactive system for ink splattering, a form of abstract art that artists splat ink onto the canvas. The default input device of our system is a pressure-sensitive 2D stylus, the most common sketching ...
