Rain Wiper: An Incremental RandomlyWired Network for Single Image Deraining
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Single image rain removal is a challenging ill-posed problem due to various shapes and densities of rain streaks. We present a novel incremental randomly wired network (IRWN) for single image deraining. Different from ... -
A Random Sampling O(n) Force-calculation Algorithm for Graph Layouts
(The Eurographics Association and John Wiley & Sons Ltd., 2019)This paper proposes a linear-time repulsive-force-calculation algorithm with sub-linear auxiliary space requirements, achieving an asymptotic improvement over the Barnes-Hut and Fast Multipole Method force-calculation ... -
Ray Classification for Accelerated BVH Traversal
(The Eurographics Association and John Wiley & Sons Ltd., 2019)For ray tracing based methods, traversing a hierarchical acceleration data structure takes up a substantial portion of the total rendering time. We propose an additional data structure which cuts off large parts of the ... -
Ray Tracing Generalized Tube Primitives: Method and Applications
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a general high-performance technique for ray tracing generalized tube primitives. Our technique efficiently supports tube primitives with fixed and varying radii, general acyclic graph structures with bifurcations, ... -
Real-Time Analytic Antialiased Text for 3-D Environments
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Text is a crucial component of 3-D environments and virtual worlds for user interfaces and wayfinding. Implementing text using standard antialiased texture mapping leads to blurry and illegible writing which hinders usability ... -
Real-time Image-based Lighting of Microfacet BRDFs with Varying Iridescence
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Iridescence is a natural phenomenon that is perceived as gradual color changes, depending on the view and illumination direction. Prominent examples are the colors seen in oil films and soap bubbles. Unfortunately, iridescent ... -
Real-time Indirect Illumination of Emissive Inhomogeneous Volumes using Layered Polygonal Area Lights
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Indirect illumination involving with visually rich participating media such as turbulent smoke and loud explosions contributes significantly to the appearances of other objects in a rendering scene. However, previous ... -
Realtime Performance‐Driven Physical Simulation for Facial Animation
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)We present the first realtime method for generating facial animations enhanced by physical simulation from realtime performance capture data. Unlike purely data‐based techniques, our method is able to produce physical ... -
Real‐Time Facial Expression Transformation for Monocular RGB Video
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)This paper describes a novel real‐time end‐to‐end system for facial expression transformation, without the need of any driving source. Its core idea is to directly generate desired and photo‐realistic facial expressions ... -
Real‐Time Human Shadow Removal in a Front Projection System
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)When a person is located between a display and an operating projector, a shadow is cast on the display. The shadow on the display may eliminate important visual information and therefore adversely affect the viewing ... -
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 ... -
A Rigging-Skinning Scheme to Control Fluid Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Inspired by skeletal animation, a novel rigging-skinning flow control scheme is proposed to animate fluids intuitively and efficiently. The new animation pipeline creates fluid animation via two steps: fluid rigging and ... -
Robust Extraction and Simplification of 2D Symmetric Tensor Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In this work, we propose a controlled simplification strategy for degenerated points in symmetric 2D tensor fields that is based on the topological notion of robustness. Robustness measures the structural stability of the ... -
Robust Reference Frame Extraction from Unsteady 2D Vector Fields with Convolutional Neural Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Robust feature extraction is an integral part of scientific visualization. In unsteady vector field analysis, researchers recently directed their attention towards the computation of near-steady reference frames for vortex ... -
Robust Structure‐Based Shape Correspondence
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a robust method to find region‐level correspondences between shapes, which are invariant to changes in geometry and applicable across multiple shape representations. We generate simplified shape graphs by jointly ... -
