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. ... -
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-, ... -
Anaglyph Caustics with Motion Parallax
(The Eurographics Association and John Wiley & Sons Ltd., 2016)In this paper we present a method to model and simulate a lens such that its caustic reveals a stereoscopic 3D image when viewed through anaglyph glasses. By interpreting lens dispersion as stereoscopic disparity, our ... -
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 ... -
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 ... -
Decoupled Space and Time Sampling of Motion and Defocus Blur for Unified Rendering of Transparent and Opaque Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We propose a unified rendering approach that jointly handles motion and defocus blur for transparent and opaque objects at interactive frame rates. Our key idea is to create a sampled representation of all parts of the ... -
Direct Shape Optimization for Strengthening 3D Printable Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Recently there has been an increasing demand for software that can help designers create functional 3D objects with required physical strength. We introduce a generic and extensible method that directly optimizes a shape ... -
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 ... -
Efficient Multi-image Correspondences for On-line Light Field Video Processing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Light field videos express the entire visual information of an animated scene, but their shear size typically makes capture, processing and display an off-line process, i. e., time between initial capture and final display ... -
An Efficient Structure-Aware Bilateral Texture Filtering for Image Smoothing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Photos contain well-structured and plentiful visual information. Edges are active and expressive stimuli for human visual perception. However, it is hard to separate structure from details because edge strength and object ... -
Efficient Volumetric PolyCube-Map Construction
(The Eurographics Association and John Wiley & Sons Ltd., 2016)PolyCubes provide compact representations for closed complex shapes and are essential to many computer graphics applications. Existing automatic PolyCube construction methods usually suffer from poor quality or time-consuming ... -
An Error Estimation Framework for Many-Light Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2016)The popularity of many-light rendering, which converts complex global illumination computations into a simple sum of the illumination from virtual point lights (VPLs), for predictive rendering has increased in recent years. ... -
An Eulerian Approach for Constructing a Map Between Surfaces With Different Topologies
(The Eurographics Association and John Wiley & Sons Ltd., 2016)3D objects of the same kind often have different topologies, and finding correspondence between them is important for operations such as morphing, attribute transfer, and shape matching. This paper presents a novel method ... -
Facial Feature Exaggeration According to Social Psychology of Face Perception
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We propose a personality trait exaggeration system emphasizing the impression of human face in images, based on multi-level features learning and exaggeration. These features are called Personality Trait Model(PTM). Abstract ... -
Feature-Aware Pixel Art Animation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Pixel art is a modern digital art in which high resolution images are abstracted into low resolution pixelated outputs using concise outlines and reduced color palettes. Creating pixel art is a labor intensive and ... -
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 ... -
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 ... -
Geometrically Based Linear Iterative Clustering for Quantitative Feature Correspondence
(The Eurographics Association and John Wiley & Sons Ltd., 2016)A major challenge in feature matching is the lack of objective criteria to determine corresponding points. Recent methods find match candidates first by exploring the proximity in descriptor space, and then rely on a ... -
Harmonic Functions for Rotational Symmetry Vector Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Representing rotational symmetry vector as a set of vectors is not suitable for design due to lacking of a consistent ordering for measurement. In this paper we introduce a spectral method to find rotation invariant harmonic ...
