Adaptive Bas-relief Generation from 3D Object under Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Bas-relief is designed to provide 3D perception for the viewers under illumination. For the problem of bas-relief generation from 3D object, most existing methods ignore the influence of illumination on bas-relief appearance. ... -
Minimal Sampling for Effective Acquisition of Anisotropic BRDFs
(The Eurographics Association and John Wiley & Sons Ltd., 2016)BRDFs are commonly used for material appearance representation in applications ranging from gaming and the movie industry, to product design and specification. Most applications rely on isotropic BRDFs due to their better ... -
Foveated Real-Time Ray Tracing for Head-Mounted Displays
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Head-mounted displays with dense pixel arrays used for virtual reality applications require high frame rates and low latency rendering. This forms a challenging use case for any rendering approach. In addition to its ability ... -
TSS BVHs: Tetrahedron Swept Sphere BVHs for Ray Tracing Subdivision Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a novel, compact bounding volume hierarchy, TSS BVH, for ray tracing subdivision surfaces computed by the Catmull-Clark scheme. We use Tetrahedron Swept Sphere (TSS) as a bounding volume to tightly bound limit ... -
Automatic Modeling of Urban Facades from Raw LiDAR Point Data
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Modeling of urban facades from raw LiDAR point data remains active due to its challenging nature. In this paper, we propose an automatic yet robust 3D modeling approach for urban facades with raw LiDAR point clouds. The ... -
Efficient Modeling of Entangled Details for Natural Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Digital landscape realism often comes from the multitude of details that are hard to model such as fallen leaves, rock piles or entangled fallen branches. In this article, we present a method for augmenting natural scenes ... -
Flow Curves: an Intuitive Interface for Coherent Scene Deformation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Effective composition in visual arts relies on the principle of movement, where the viewer's eye is directed along subjective curves to a center of interest. We call these curves subjective because they may span the edges ... -
Re-Compositable Panoramic Selfie with Robust Multi-Frame Segmentation and Stitching
(The Eurographics Association and John Wiley & Sons Ltd., 2016)It is a challenging task for ordinary users to capture selfies with a good scene composition, given the limited freedom to position the camera. Creative hardware (e.g., selfie sticks) and software (e.g., panoramic selfie ... -
Skeleton-driven Adaptive Hexahedral Meshing of Tubular Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We propose a novel method for the automatic generation of structured hexahedral meshes of articulated 3D shapes. We recast the complex problem of generating the connectivity of a hexahedral mesh of a general shape into the ... -
Non-Local Sparse and Low-Rank Regularization for Structure-Preserving Image Smoothing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)This paper presents a new image smoothing method that better preserves prominent structures. Our method is inspired by the recent non-local image processing techniques on the patch grouping and filtering. Overall, it has ... -
Image Recoloring with Valence-Arousal Emotion Model
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We introduce an affective image recoloring method for changing the overall mood in the image in a numerically measurable way. Given a semantically segmented source image and a target emotion, our system finds reference ... -
Anisotropic Superpixel Generation Based on Mahalanobis Distance
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Superpixels have been widely used as a preprocessing step in various computer vision tasks. Spatial compactness and color homogeneity are the two key factors determining the quality of the superpixel representation. In ... -
Appearance Harmonization for Single Image Shadow Removal
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Shadow removal is a challenging problem and previous approaches often produce de-shadowed regions that are visually inconsistent with the rest of the image. We propose an automatic shadow region harmonization approach that ... -
Piecewise-planar Reconstruction of Multi-room Interiors with Arbitrary Wall Arrangements
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Reconstructing the as-built architectural shape of building interiors has emerged in recent years as an important and challenging research problem. An effective approach must be able to faithfully capture the architectural ... -
Incremental Deformation Subspace Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Recalculating the subspace basis of a deformable body is a mandatory procedure for subspace simulation, after the body gets modified by interactive applications. However, using linear modal analysis to calculate the basis ... -
Piecewise Smooth Reconstruction of Normal Vector Field on Digital Data
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We propose a novel method to regularize a normal vector field defined on a digital surface (boundary of a set of voxels). When the digital surface is a digitization of a piecewise smooth manifold, our method localizes sharp ... -
3D Body Shapes Estimation from Dressed-Human Silhouettes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Estimation of 3D body shapes from dressed-human photos is an important but challenging problem in virtual fitting. We propose a novel automatic framework to efficiently estimate 3D body shapes under clothes. We construct ... -
Temporally Coherent and Artistically Intended Stylization of Feature Lines Extracted from 3D Models
(The Eurographics Association and John Wiley & Sons Ltd., 2016)In this paper, we propose a method to maintain the temporal coherence of stylized feature lines extracted from 3D models and preserve an artistically intended stylization provided by the user. We formally define the problem ... -
Aesthetic Rating and Color Suggestion for Color Palettes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)A model to rate color combinations that considers human aesthetic preferences is proposed. The proposed method does not assume that a color palette has a specific number of colors, i.e., input is not restricted to a two-, ... -
A Study On Designing Effective Introductory Materials for Information Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Designing introductory materials is extremely important when developing new information visualization techniques. All users, regardless of their domain knowledge, first must learn how to interpret the visually encoded ...
