Data-Driven Fire Synthesis and Design
(The Eurographics Association, 2014)We present a data-driven synthesis approach to design and animate fires in desired shapes and motions. At the preprocessing stage, our system simulates a set of basis fires under specific simulation configurations and ... -
Example-based Haze Removal with two-layer Gaussian Process Regressions
(The Eurographics Association, 2014)Hazy images suffer from low visibility and contrast. Researchers have devoted great efforts to haze removal with the prior assumptions on observations in the past decade. However, these priors from observations can provide ... -
Extraction and Transfer of Facial Expression Wrinkles for Facial Performance Enhancement
(The Eurographics Association, 2014)Creating realistic models and animations of human faces with adequate level of detail is very challenging due to the high complexity of facial deformations and the sensitivity of the human visual system to human faces. One ... -
Finding Feature Similarities Between Geometric Trees
(The Eurographics Association, 2014)Geometric trees are graphs with no cycles in which the nodes have spatial co-ordinates and the edges are geometric curves. Many physical systems can be represented effectively using geometric trees, e.g. river beds, animal ... -
Geometry-Aware Image Completion via Multiple Examples
(The Eurographics Association, 2014)When browsing through photographs taken during a trip, it can be a distressing discovery to find many other bystanders captured within the frame. A visually compelling snapshot preserves the desired subject in the foreground, ... -
Image Palette: Brushstroke Synthesis-based Style Transfer
(The Eurographics Association, 2014)Painting style transfer is one kind technology where given the sample images with some specific art style, we can render the target images in the same style as the samples after some computation. In this paper we present ... -
Incorporating Fiber Controls into FEM Model for Transversely Isotropic Materials
(The Eurographics Association, 2014)Physically plausible deformable models based on continuum mechanics have been a hot topic in computer graphics for decades, and many models have been proposed to improve performance speed and stability. However, most of ... -
Integrating Occlusion Culling into LOD on GPU
(The Eurographics Association, 2014)Real-time rendering of complex 3D models is still a very challenging task. Recently, GPU-based level-of-detail (LOD) approaches have been proposed to fast decrease the complexity of a 3D model, but applying only LOD ... -
Parallel BTF Compression with Multi-Level Vector Quantization in OpenCL
(The Eurographics Association, 2014)Bidirectional Texture Function (BTF) as an effective visual fidelity representation of surface appearance is becoming more and more widely used. In this paper we report on contributions to BTF data compression for multi-level ... -
PatchMove: Patch-based Fast Image Interpolation with Greedy Bidirectional Correspondence
(The Eurographics Association, 2014)In this paper, we present a method for the plausible interpolation of images. This method has several applications, such as for smooth view interpolation, low frame-rate video upsampling, and animation. The central idea ... -
Perceptually Optimised Illumination for Seamless Composites
(The Eurographics Association, 2014)Realistic illumination in composition is important for a seamless mixture between the virtual and real world objects in visual effects and mixed reality. The seamlessness is the measure of how perceivably apparent the ... -
Projecting Points onto Planar Parametric Curves by Local Biarc Approximation
(The Eurographics Association, 2014)This paper proposes a geometric iteration algorithm for computing point projection and inversion on surfaces based on local biarc approximation. The iteration begins with initial estimation of the projection of the prescribed ... -
Quantitative Analysis of Voxel Raytracing Acceleration Structures
(The Eurographics Association, 2014)In this work, we provide a comprehensive analysis of GPU acceleration structures for voxel raytracing. We compare the commonly used octrees to BVH and KD trees, which are the standard in GPU triangle raytracing. Evaluating ... -
Random Sparse Coded Aperture for Lensless Imaging
(The Eurographics Association, 2014)This paper develops a computational lensless imaging system based on a random sparse coded aperture. The camera consists of a thin mask with a coded pattern and a standard sensor array. The proposed coded aperture contains ... -
Real-time Collision Detection with Two-level Spatial Hashing on GPU
(The Eurographics Association, 2014)In this paper, a two-level parallel spatial hashing method is presented for real-time collision detection of deformable objects based on modern GPU architecture. The second-level of spatial hashing is used to improve the ... -
Saliency-driven Depth Compression for 3D Image Warping
(The Eurographics Association, 2014)Current compression methods compress depth images by incorporating 2D features, which leads to a loss of the detail of the original 3D object in the recovered depth image. The main idea of this paper is to augment 2D ... -
Scene Segmentation and Understanding for Context-Free Point Clouds
(The Eurographics Association, 2014)The continuous development of new commodity hardware intended to capture the surface structure of objects is quickly making point cloud data ubiquitous. Scene understanding methods address the problem of determining the ... -
A Simple Artistic Rendering Method for Stereoscopic Images
(The Eurographics Association, 2014)General painterly rendering algorithms cannot be used to render stereo image pair separately because they may produce random noise and lead to inconsistency between binocular images. In this paper, a generic rendering ... -
Sky Browser: Search for HDR Sky Maps
(The Eurographics Association, 2014)In a visual effects studio for movie production, sky maps play an important role for acting as a sky backdrop to a scene. The backdrop to a scene is often represented using a high-resolution sky map. This motivates the ... -
Surface Mesh Segmentation and Reconstruction with Smooth Boundary Curves
(The Eurographics Association, 2014)In mesh segmentation for industrial design objects, each segment defined by a region with closed boundary should correspond to its underlying surface constructed according to the designer's intention. In order to generate ...
