Active Scene Understanding via Online Semantic Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose a novel approach to robot-operated active understanding of unknown indoor scenes, based on online RGBD reconstruction with semantic segmentation. In our method, the exploratory robot scanning is both driven by ... -
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 ... -
Appearance Flow Completion for Novel View Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Novel view synthesis from sparse and unstructured input views faces challenges like the difficulty with dense 3D reconstruction and large occlusion. This paper addresses these problems by estimating proper appearance flows ... -
Automatic Modeling of Cluttered Multi-room Floor Plans From Panoramic Images
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a novel and light-weight approach to capture and reconstruct structured 3D models of multi-room floor plans. Starting from a small set of registered panoramic images, we automatically generate a 3D layout of the ... -
A Color-Pair Based Approach for Accurate Color Harmony Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Harmonious color combinations can stimulate positive user emotional responses. However, a widely open research question is: how can we establish a robust and accurate color harmony measure for the public and professional ... -
Compacting Voxelized Polyhedra via Tree Stacking
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Volume compaction is a geometric problem that aims to reduce the volume of a polyhedron via shape transform. Compactable structures are easier to transport and in some cases easier to manufacture, therefore, they are ... -
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 ... -
Deep Line Drawing Vectorization via Line Subdivision and Topology Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Vectorizing line drawing is necessary for the digital workflows of 2D animation and engineering design. But it is challenging due to the ambiguity of topology, especially at junctions. Existing vectorization methods either ... -
Deep Video-Based Performance Synthesis from Sparse Multi-View Capture
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a deep learning based technique that enables novel-view videos of human performances to be synthesized from sparse multi-view captures. While performance capturing from a sparse set of videos has received ... -
Desertscapes Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present an interactive aeolian simulation to author hot desert scenery. Wind is an important erosion agent in deserts which, despite its importance, has been neglected in computer graphics. Our framework overcomes this ... -
Discrete Calabi Flow: A Unified Conformal Parameterization Method
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Conformal parameterization for surfaces into various parameter domains is a fundamental task in computer graphics. Prior research on discrete Ricci flow provided us with promising inspirations from methods derived via ... -
Distribution Update of Deformable Patches for Texture Synthesis on the Free Surface of Fluids
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose an approach for temporally coherent patch-based texture synthesis on the free surface of fluids. Our approach is applied as a post-process, using the surface and velocity field from any fluid simulator. We apply ... -
Dual Illumination Estimation for Robust Exposure Correction
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Exposure correction is one of the fundamental tasks in image processing and computational photography. While various methods have been proposed, they either fail to produce visually pleasing results, or only work well for ... -
Field-aligned Quadrangulation for Image Vectorization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Image vectorization is an important yet challenging problem, especially when the input image has rich content. In this paper, we develop a novel method for automatically vectorizing natural images with feature-aligned ... -
Figure Skating Simulation from Video
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Figure skating is one of the most popular ice sports at the Winter Olympic Games. The skaters perform several skating skills to express the beauty of the art on ice. Skating involves moving on ice while wearing skate shoes ... -
FontRNN: Generating Large-scale Chinese Fonts via Recurrent Neural Network
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Despite the recent impressive development of deep neural networks, using deep learning based methods to generate largescale Chinese fonts is still a rather challenging task due to the huge number of intricate Chinese glyphs, ... -
A Generalized Cubemap for Encoding 360° VR Videos using Polynomial Approximation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)360° VR videos provide users with an immersive visual experience. To encode 360° VR videos, spherical pixels must be mapped onto a two-dimensional domain to take advantage of the existing video encoding and storage standards. ... -
