GazeDirector: Fully Articulated Eye Gaze Redirection in Video
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present GazeDirector, a new approach for eye gaze redirection that uses model-fitting. Our method first tracks the eyes by fitting a multi-part eye region model to video frames using analysis-by-synthesis, thereby ... -
A General Illumination Model for Molecular Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Several visual representations have been developed over the years to visualize molecular structures, and to enable a better understanding of their underlying chemical processes. Today, the most frequently used atom-based ... -
Generative Adversarial Image Super-Resolution Through Deep Dense Skip Connections
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Recently, image super-resolution works based on Convolutional Neural Networks (CNNs) and Generative Adversarial Nets (GANs) have shown promising performance. However, these methods tend to generate blurry and over-smoothed ... -
GPU-based Polynomial Finite Element Matrix Assembly for Simplex Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we present a matrix assembly technique for arbitrary polynomial order finite element simulations on simplex meshes for graphics processing units (GPU). Compared to the current state of the art in GPU-based ... -
Guidelines for Quantitative Evaluation of Medical Visualizations on the Example of 3D Aneurysm Surface Comparisons
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)Medical visualizations are highly adapted to a specific medical application scenario. Therefore, many researchers conduct qualitative evaluations with a low number of physicians or medical experts to assess the benefits ... -
Hair Modeling and Simulation by Style
(The Eurographics Association and John Wiley & Sons Ltd., 2018)As the deformation behaviors of hair strands vary greatly depending on the hairstyle, the computational cost and accuracy of hair movement simulations can be significantly improved by applying simulation methods specific ... -
HairControl: A Tracking Solution for Directable Hair Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a method for adding artistic control to physics-based hair simulation. Taking as input an animation of a coarse set of guide hairs, we constrain a subsequent higher-resolution simulation of detail hairs to follow ... -
Handling Fluorescence in a Uni-directional Spectral Path Tracer
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present two separate improvements to the handling of fluorescence effects in modern uni-directional spectral rendering systems. The first is the formulation of a new distance tracking scheme for fluorescent volume ... -
Hierarchical Correlation Clustering in Multiple 2D Scalar Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Sets of multiple scalar fields can be used to model many types of variation in data, such as uncertainty in measurements and simulations or time-dependent behavior of scalar quantities. Many structural properties of such ... -
Hierarchical Quad Meshing of 3D Scanned Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper we present a novel method to reconstruct watertight quad meshes on scanned 3D geometry. There exist many different approaches to acquire 3D information from real world objects and sceneries. Resulting point ... -
Human Factors in Streaming Data Analysis: Challenges and Opportunities for Information Visualization
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)Real‐world systems change continuously. In domains such as traffic monitoring or cyber security, such changes occur within short time scales. This results in a streaming data problem and leads to unique challenges for the ... -
Hunting High and Low: Visualising Shifting Correlations in Financial Markets
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The analysis of financial assets' correlations is fundamental to many aspects of finance theory and practice, especially modern portfolio theory and the study of risk. In order to manage investment risk, in-depth analysis ... -
Hypersliceplorer: Interactive Visualization of Shapes in Multiple Dimensions
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper we present Hypersliceplorer, an algorithm for generating 2D slices of multi-dimensional shapes defined by a simplical mesh. Often, slices are generated by using a parametric form and then constraining parameters ... -
Illustrative Multivariate Visualization for Geological Modelling
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we present a novel illustrative multivariate visualization for geological modelling to assist geologists and reservoir engineers in visualizing multivariate datasets in superimposed representations, in ... -
An Implicit SPH Formulation for Incompressible Linearly Elastic Solids
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)We propose a novel smoothed particle hydrodynamics (SPH) formulation for deformable solids. Key aspects of our method are implicit elastic forces and an adapted SPH formulation for the deformation gradient that—in contrast ... -
Improved Corners with Multi‐Channel Signed Distance Fields
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)We propose an extension to the state‐of‐the‐art text rendering technique based on sampling a 2D signed distance field from a texture. This extension significantly improves the visual quality of sharp corners, which is the ... -
