Dispersion-based Color Projection using Masked Prisms
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a method for projecting arbitrary color images using a white light source and an optical device with no colored components - consisting solely of one or two prisms and two transparent masks. When illuminated, ... -
Contrast-Enhanced Black and White Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper investigates contrast enhancement as an approach to tone reduction, aiming to convert a photograph to black and white. Using a filter-based approach to strengthen contrast, we avoid making a hard decision about ... -
Ray Specialized Contraction on Bounding Volume Hierarchies
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper we propose a simple but effective method to modify a BVH based on ray distribution for improved ray tracing performance. Our method starts with an initial BVH generated by any state-of-the-art offline algorithm. ... -
Skeleton based Vertex Connection Resampling for Bidirectional Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Bidirectional path tracing is known to perform poorly for the rendering of highly occluded scenes. Indeed, the connection strategy between light and eye subpaths does not take into account the visibility factor, presenting ... -
Deformable Objects Collision Handling with Fast Convergence
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a stable and efficient simulator for deformable objects with collisions and contacts. For stability, an optimization derived from the implicit time integrator is solved in each timestep under the inequality ... -
An Efficient Feathering System with Collision Control
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an efficient interactive system for dressing a naked bird with feathers. In our system, a skeleton associated with guide feathers is used to describe the distribution of the body feathers. The special skeleton ... -
TightCCD: Efficient and Robust Continuous Collision Detection using Tight Error Bounds
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a realtime and reliable continuous collision detection (CCD) algorithm between triangulated models that exploits the floating point hardware capability of current CPUs and GPUs. Our formulation is based on ... -
Brushables: Example-based Edge-aware Directional Texture Painting
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper we present Brushables-a novel approach to example-based painting that respects user-specified shapes at the global level and preserves textural details of the source image at the local level. We formulate the ... -
Data-driven Handwriting Synthesis in a Conjoined Manner
(The Eurographics Association and John Wiley & Sons Ltd., 2015)A person's handwriting appears differently within a typical range of variations, and the shapes of handwriting characters also show complex interaction with their nearby neighbors. This makes automatic synthesis of handwriting ... -
FlexyFont: Learning Transferring Rules for Flexible Typeface Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Maintaining consistent styles across glyphs is an arduous task in typeface design. In this work we introduce Flexy- Font, a flexible tool for synthesizing a complete typeface that has a consistent style with a given small ... -
Tone- and Feature-Aware Circular Scribble Art
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Circular scribble art is a kind of line drawing where the seemingly random, noisy and shapeless circular scribbles at microscopic scale constitute astonishing grayscale images at macroscopic scale. Such a delicate skill ... -
Multiple Facial Image Editing Using Edge-Aware PDE Learning
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper introduces a novel facial editing tool, called edge-aware mask, to achieve multiple photo-realistic rendering effects in a unified framework. The edge-aware masks facilitate three basic operations for adaptive ... -
Evaluating the Quality of Face Alignment without Ground Truth
(The Eurographics Association and John Wiley & Sons Ltd., 2015)The study of face alignment has been an area of intense research in computer vision, with its achievements widely used in computer graphics applications. The performance of various face alignment methods is often imagedependent ... -
Efficient Variational Light Field View Synthesis For Making Stereoscopic 3D Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel approach for making stereoscopic images by variational view synthesis on the multi-perspective light field. With the intended disparities as constraints, we specialize the generative variational model ... -
DenseCut: Densely Connected CRFs for Realtime GrabCut
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Figure-ground segmentation from bounding box input, provided either automatically or manually, has been extremely popular in the last decade and influenced various applications. A lot of research has focused on highquality ... -
4D Model Flow: Precomputed Appearance Alignment for Real-time 4D Video Interpolation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce the concept of 4D model flow for the precomputed alignment of dynamic surface appearance across 4D video sequences of different motions reconstructed from multi-view video. Precomputed 4D model flow allows the ... -
An Efficient Boundary Handling with a Modified Density Calculation for SPH
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a new boundary handling method for smoothed particle hydrodynamics (SPH). Previous approaches required the use of boundary particles to prevent particles from sticking to the boundary. We address this issue by ... -
EasyXplorer: A Flexible Visual Exploration Approach for Multivariate Spatial Data
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Exploring multivariate spatial data attracts much attention in the visualization community. The main challenge lies in that automatic analysis techniques is insufficient in discovering complicated patterns with the perspective ... -
Geometrically Exact Simulation of Inextensible Ribbon
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Narrow, inextensible, and naturally flat ribbons have some special and interesting phenomena under isometric deformations. Although a ribbon has a shape between rod and shell, directly applying the geometric representation ... -
Interactive Rigging with Intuitive Tools
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Rigging is a core element in the process of bringing a 3D character to life. The rig defines and delimits the motions of the character and provides an interface for an animator with which to interact with the 3D character. ...
