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 ... -
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 ... -
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 ... -
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 ... -
Accurate Synthesis of Multi-Class Disk Distributions
(The Eurographics Association and John Wiley & Sons Ltd., 2019)While analysing and synthesising 2D distributions of points has been applied both to the generation of textures with discrete elements and for populating virtual worlds with 3D objects, the results are often inaccurate ... -
Hierarchical Rasterization of Curved Primitives for Vector Graphics Rendering on the GPU
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In this paper, we introduce the CPatch, a curved primitive that can be used to construct arbitrary vector graphics. A CPatch is a generalization of a 2D polygon: Any number of curves up to a cubic degree bound a primitive. ... -
Deep Video-Based Performance Cloning
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a new video-based performance cloning technique. After training a deep generative network using a reference video capturing the appearance and dynamics of a target actor, we are able to generate videos where ... -
Multi-Pose Interactive Linkage Design
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We introduce an interactive tool for novice users to design mechanical objects made of 2.5D linkages. Users simply draw the shape of the object and a few key poses of its multiple moving parts. Our approach automatically ... -
A Geometrically Consistent Viscous Fluid Solver with Two-Way Fluid-Solid Coupling
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a grid-based fluid solver for simulating viscous materials and their interactions with solid objects. Our method formulates the implicit viscosity integration as a minimization problem with consistently estimated ... -
Character Navigation in Dynamic Environments Based on Optical Flow
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Steering and navigation are important components of character animation systems to enable them to autonomously move in their environment. In this work, we propose a synthetic vision model that uses visual features to steer ... -
A Low-Dimensional Function Space for Efficient Spectral Upsampling
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a versatile technique to convert textures with tristimulus colors into the spectral domain, allowing such content to be used in modern rendering systems. Our method is based on the observation that suitable ... -
Exact Constraint Satisfaction for Truly Seamless Parametrization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In the field of global surface parametrization a recent focus has been on so-called seamless parametrization. This term refers to parametrization approaches which, while using an atlas of charts to enable the handling of ... -
Design and Automated Generation of Japanese Picture Puzzles
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We introduce the generalized nonogram, an extension of the well-known nonogram or Japanese picture puzzle. It is not based on a regular square grid but on a subdivision (arrangement) with differently shaped cells, bounded ... -
Neural BTF Compression and Interpolation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)The Bidirectional Texture Function (BTF) is a data-driven solution to render materials with complex appearance. A typical capture contains tens of thousands of images of a material sample under varying viewing and lighting ... -
Generating Color Scribble Images using Multi-layered Monochromatic Strokes Dithering
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Color scribbling is a unique form of illustration where artists use compact, overlapping, and monochromatic scribbles at microscopic scale to create astonishing colorful images at macroscopic scale. The creation process ... -
Generating Stochastic Wall Patterns On-the-fly with Wang Tiles
(The Eurographics Association and John Wiley & Sons Ltd., 2019)The game and movie industries always face the challenge of reproducing materials. This problem is tackled by combining illumination models and various textures (painted or procedural patterns). Generating stochastic wall ... -
StyleBlit: Fast Example-Based Stylization with Local Guidance
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present StyleBlit-an efficient example-based style transfer algorithm that can deliver high-quality stylized renderings in real-time on a single-core CPU. Our technique is especially suitable for style transfer applications ... -
A CNN-based Flow Correction Method for Fast Preview
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Eulerian-based smoke simulations are sensitive to the initial parameters and grid resolutions. Due to the numerical dissipation on different levels of the grid and the nonlinearity of the governing equations, the differences ... -
