Practical Person-Specific Eye Rigging
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a novel parametric eye rig for eye animation, including a new multi-view imaging system that can reconstruct eye poses at submillimeter accuracy to which we fit our new rig. This allows us to accurately estimate ... -
Global Texture Mapping for Dynamic Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose a novel framework to generate a global texture atlas for a deforming geometry. Our approach distinguishes from prior arts in two aspects. First, instead of generating a texture map for each timestamp to color a ... -
Deep HDR Video from Sequences with Alternating Exposures
(The Eurographics Association and John Wiley & Sons Ltd., 2019)A practical way to generate a high dynamic range (HDR) video using off-the-shelf cameras is to capture a sequence with alternating exposures and reconstruct the missing content at each frame. Unfortunately, existing ... -
Incremental Labelling of Voronoi Vertices for Shape Reconstruction
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)We present an incremental Voronoi vertex labelling algorithm for approximating contours, medial axes and dominant points (high curvature points) from 2D point sets. Though there exist many number of algorithms for ... -
Learning to Predict Image-based Rendering Artifacts with Respect to a Hidden Reference Image
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Image metrics predict the perceived per-pixel difference between a reference image and its degraded (e. g., re-rendered) version. In several important applications, the reference image is not available and image metrics ... -
Gradient‐Guided Local Disparity Editing
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)Stereoscopic 3D technology gives visual content creators a new dimension of design when creating images and movies. While useful for conveying emotion, laying emphasis on certain parts of the scene, or guiding the viewer's ... -
Automatic Generation of Vivid LEGO Architectural Sculptures
(© 2019 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2019)Brick elements are very popular and have been widely used in many areas, such as toy design and architectural fields. Designing a vivid brick sculpture to represent a three‐dimensional (3D) model is a very challenging task, ... -
Computing Surface PolyCube-Maps by Constrained Voxelization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a novel method to compute bijective PolyCube-maps with low isometric distortion. Given a surface and its preaxis- aligned shape that is not an exact PolyCube shape, the algorithm contains two steps: (i) construct ... -
An Analysis of Region Clustered BVH Volume Rendering on GPU
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a Direct Volume Rendering method that makes use of newly available Nvidia graphics hardware for Bounding Volume Hierarchies. Using BVHs for DVR has been overlooked in recent research due to build times potentially ... -
Gradient Outlier Removal for Gradient-Domain Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a new outlier removal technique for a gradient-domain path tracing (G-PT) that computes image gradients as well as colors. Our approach rejects gradient outliers whose estimated errors are much higher than those ... -
Anisotropic Surface Remeshing without Obtuse Angles
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a novel anisotropic surface remeshing method that can efficiently eliminate obtuse angles. Unlike previous work that can only suppress obtuse angles with expensive resampling and Lloyd-type iterations, our method ... -
An Efficient Solution to Structured Optimization Problems using Recursive Matrices
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a linear algebra framework for structured matrices and general optimization problems. The matrices and matrix operations are defined recursively to efficiently capture complex structures and enable advanced ... -
The State of the Art in Multilayer Network Visualization
(© 2019 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2019)Modelling relationship between entities in real‐world systems with a simple graph is a standard approach. However, reality is better embraced as several interdependent subsystems (or layers). Recently, the concept of a ... -
Latent Space Cartography: Visual Analysis of Vector Space Embeddings
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Latent spaces-reduced-dimensionality vector space embeddings of data, fit via machine learning-have been shown to capture interesting semantic properties and support data analysis and synthesis within a domain. Interpretation ... -
A Subspace Method for Fast Locally Injective Harmonic Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a fast algorithm for low-distortion locally injective harmonic mappings of genus 0 triangle meshes with and without cone singularities. The algorithm consists of two portions, a linear subspace analysis and ... -
DIVA: Exploration and Validation of Hypothesized Drug-Drug Interactions
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Adverse reactions caused by drug-drug interactions are a major public health concern. Currently, adverse reaction signals are detected through a tedious manual process in which drug safety analysts review a large number ... -
Controllable Image‐Based Transfer of Flow Phenomena
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)Modelling flow phenomena and their related weathering effects is often cumbersome due their dependence on the environment, materials and geometric properties of objects in the scene. Example‐based modelling provides many ... -
Functional Maps Representation On Product Manifolds
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)We consider the tasks of representing, analysing and manipulating maps between shapes. We model maps as densities over the product manifold of the input shapes; these densities can be treated as scalar functions and therefore ... -
Shadow Inpainting and Removal Using Generative Adversarial Networks with Slice Convolutions
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In this paper, we propose a two-stage top-down and bottom-up Generative Adversarial Networks (TBGANs) for shadow inpainting and removal which uses a novel top-down encoder and a bottom-up decoder with slice convolutions. ... -
Reliable Rolling-guided Point Normal Filtering for Surface Texture Removal
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Semantic surface decomposition (SSD) facilitates various geometry processing and product re-design tasks. Filter-based techniques are meaningful and widely used to achieve the SSD, which however often leads to surface ...
