2D-3D Lifting for Shape Reconstruction
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present an algorithm for shape reconstruction from incomplete 3D scans by fusing together two acquisition modes: 2D photographs and 3D scans. The two modes exhibit complementary characteristics: scans have depth ... -
Adaptive Multi-scale Analysis for Point-based Surface Editing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper presents a tool that enables the direct editing of surface features in large point-clouds or meshes. This is made possible by a novel multi-scale analysis of unstructured point-clouds that automatically extracts ... -
Advanced Hybrid Particle-Grid Method with Sub-Grid Particle Correction
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper proposes a novel hybrid particle-grid approach to liquid simulation, which uses the fluid-implicitparticle (FLIP) method to resolve the liquid motion and a grid-based particle correction method to complement ... -
Anisotropic Geodesics for Live-wire Mesh Segmentation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present an interactive method for mesh segmentation that is inspired by the classical live-wire interaction for image segmentation. The core contribution of the work is the definition and computation of wires on surfaces ... -
Approximate Symmetry Detection in Partial 3D Meshes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Symmetry is a common characteristic in natural and man-made objects. Its ubiquitous nature can be exploited to facilitate the analysis and processing of computational representations of real objects. In particular, in ... -
Automatic 3D Indoor Scene Updating with RGBD Cameras
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Since indoor scenes are frequently changed in daily life, such as re-layout of furniture, the 3D reconstructions for them should be flexible and easy to update. We present an automatic 3D scene update algorithm to indoor ... -
A Data-Driven Framework for Visual Crowd Analysis
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel approach for analyzing the quality of multi-agent crowd simulation algorithms. Our approach is data-driven, taking as input a set of user-defined metrics and reference training data, either synthetic or ... -
Data-Driven Reconstruction of Human Locomotion Using a Single Smartphone
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Generating a visually appealing human motion sequence using low-dimensional control signals is a major line of study in the motion research area in computer graphics. We propose a novel approach that allows us to reconstruct ... -
Editing and Synthesizing Two-Character Motions using a Coupled Inverted Pendulum Model
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This study aims to develop a controller for use in the online simulation of two interacting characters. This controller is capable of generalizing two sets of interaction motions of the two characters based on the relationships ... -
Efficient Depth Propagation for Constructing a Layered Depth Image from a Single Image
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we propose an interactive technique for constructing a 3D scene via sparse user inputs. We represent a 3D scene in the form of a Layered Depth Image (LDI) which is composed of a foreground layer and a ... -
Environment-Adaptive Contact Poses for Virtual Characters
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel method to generate a virtual character's multi-contact poses adaptive to the various shapes of the environment. Given the user-specified center of mass (CoM) position and direction as inputs, our method ... -
Fast and Scalable Mesh Superfacets
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In the field of computer vision, the introduction of a low-level preprocessing step to oversegment images into superpixels - relatively small regions whose boundaries agree with those of the semantic entities in the scene ... -
Fast Feature-Oriented Visual Connection for Large Image Collections
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Deriving the visual connectivity across large image collections is a computationally expensive task. Different from current image-oriented match graph construction methods which build on pairwise image matching, we present ... -
Fractional Reyes-Style Adaptive Tessellation for Continuous Level of Detail
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper we present a fractional parametric splitting scheme for Reyes-style adaptive tessellation. Our parallel algorithm generates crack-free tessellation from a parametric surface, which is also free of sudden ... -
G2 Surface Interpolation Over General Topology Curve Networks
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The basic idea of curve network-based design is to construct smoothly connected surface patches, that interpolate boundaries and cross-derivatives extracted from the curve network. While the majority of applications demands ... -
Hybrid Particle-grid Modeling for Multi-scale Droplet/Spray Simulation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper presents a novel hybrid particle-grid method that tightly couples Lagrangian particle approach with Eulerian grid approach to simulate multi-scale diffuse materials varying from disperse droplets to dissipating ... -
Illuminant Aware Gamut-Based Color Transfer
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper proposes a new approach for color transfer between two images. Our method is unique in its consideration of the scene illumination and the constraint that the mapped image must be within the color gamut of the ... -
Incompressible SPH using the Divergence-Free Condition
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present a novel SPH framework to simulate incompressible fluid that satisfies both the divergencefree condition and the density-invariant condition. In our framework, the two conditions are applied ... -
Interactive Image-Guided Modeling of Extruded Shapes
