Time-Lapse Photometric Stereo and Applications
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper presents a technique to recover geometry from time-lapse sequences of outdoor scenes. We build upon photometric stereo techniques to recover approximate shadowing, shading and normal components allowing us to ... -
Perceptually-motivated Stereoscopic Film Grain
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Independent management of film grain in each view of a stereoscopic video can lead to visual discomfort. The existing alternative is to project the grain onto the scene geometry. Such grain, however, looks unnatural, changes ... -
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 ... -
Single-shot High Dynamic Range Imaging Using Coded Electronic Shutter
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Typical high dynamic range (HDR) imaging approaches based on multiple images have difficulties in handling moving objects and camera shakes, suffering from the ghosting effect and the loss of sharpness in the output HDR ... -
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 ... -
Perceptually-based Color Assignment
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Color assignment is a complex task of incorporating and balancing area configuration, color harmony, and user's intent. In this paper, we present a novel method for automatic color assignment based on theories of color ... -
Learning Natural Colors for Image Recoloring
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a data-driven method for automatically recoloring a photo to enhance its appearance or change a viewer's emotional response to it. A compact representation called a RegionNet summarizes color and geometric ... -
Making in-Front-of Cars Transparent: Sharing First-Person-Views via Dashcam
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Visual obstruction caused by a preceding vehicle is one of the key factors threatening driving safety. One possible solution is to share the first-person-view of the preceding vehicle to unveil the blocked field-of-view ... -
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 ... -
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 ... -
Realistic Road Path Reconstruction from GIS Data
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We introduce a new approach to construct smooth piecewise curves representing realistic road paths. Given a GIS database of road networks in which sampled points are organized in 3D polylines, our method creates horizontal, ... -
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 ... -
Sparse Localized Decomposition of Deformation Gradients
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Sparse localized decomposition is a useful technique to extract meaningful deformation components out of a training set of mesh data. However, existing methods cannot capture large rotational motion in the given mesh ... -
Real-Time Symmetry-Preserving Deformation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we address the problem of structure-aware shape deformation: We specifically consider deformations that preserve symmetries of the shape being edited. While this is an elegant approach for obtaining plausible ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
