Blur-Aware Image Downsampling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Resizing to a lower resolution can alter the appearance of an image. In particular, downsampling an image causes blurred regions to appear sharper. It is useful at times to create a downsampled version of the image that ... -
BSSRDF Estimation from Single Images
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a novel method to estimate an approximation of the reflectance characteristics of optically thick, homogeneous translucent materials using only a single photograph as input. First, we approximate the diffusion ... -
Combinatorial Bidirectional Path-Tracing for Efficient Hybrid CPU/GPU Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents a reformulation of bidirectional path-tracing that adequately divides the algorithm into processes efficiently executed in parallel on both the CPU and the GPU. We thus benefit from high-level optimization ... -
Component-wise Controllers for Structure-Preserving Shape Manipulation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Recent shape editing techniques, especially for man-made models, have gradually shifted focus from maintaining local, low-level geometric features to preserving structural, high-level characteristics like symmetry and ... -
Comprehensive Facial Performance Capture
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a system for recording a live dynamic facial performance, capturing highly detailed geometry and spatially varying diffuse and specular reflectance information for each frame of the performance. The result is a ... -
Computer-Suggested Facial Makeup
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Finding the best makeup for a given human face is an art in its own right. Experienced makeup artists train for years to be skilled enough to propose a best-fit makeup for an individual. In this work we propose a system ... -
Contouring Discrete Indicator Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a method for calculating the boundary of objects from Discrete Indicator Functions that store 2- material volume fractions with a high degree of accuracy. Although Marching Cubes and its derivatives are effective ... -
Deformable Motion: Squeezing into Cluttered Environments
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present an interactive method that allows animated characters to navigate through cluttered environments. Our characters are equipped with a variety of motion skills to clear obstacles, narrow passages, and highly ... -
Discovery of Intrinsic Primitives on Triangle Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The discovery of meaningful parts of a shape is required for many geometry processing applications, such as parameterization, shape correspondence, and animation. It is natural to consider primitives such as spheres, ... -
Dynamic Display of BRDFs
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper deals with the challenge of physically displaying reflectance, i.e., the appearance of a surface and its variation with the observer position and the illuminating environment. This is commonly described by the ... -
Estimating Color and Texture Parameters for Vector Graphics
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Diffusion curves are a powerful vector graphic representation that stores an image as a set of 2D Bezier curves with colors defined on either side. These colors are diffused over the image plane, resulting in smooth color ... -
Freehand HDR Imaging of Moving Scenes with Simultaneous Resolution Enhancement
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Despite their high popularity, common high dynamic range (HDR) methods are still limited in their practical applicability: They assume that the input images are perfectly aligned, which is often violated in practise. Our ... -
Fruit Senescence and Decay Simulation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Aging and imperfections provide important visual cues for realism. We present a novel physically-based approach for simulating the biological aging and decay process in fruits. This method simulates interactions between ... -
Generalized Helicoids for Modeling Hair Geometry
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In computer graphics, modeling the geometry of hair and hair-like patterns such as grass and fur remains a significant challenge. Hair strands can exist in an extensive variety of arrangements and the choice of an appropriate ... -
GeoBrush: Interactive Mesh Geometry Cloning
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We propose a method for interactive cloning of 3D surface geometry using a paintbrush interface, similar to the continuous cloning brush popular in image editing. Existing interactive mesh composition tools focus on atomic ... -
Global Structure Optimization of Quadrilateral Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We introduce a fully automatic algorithm which optimizes the high-level structure of a given quadrilateral mesh to achieve a coarser quadrangular base complex. Such a topological optimization is highly desirable, since ... -
Goal-based Caustics
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We propose a novel system for designing and manufacturing surfaces that produce desired caustic images when illuminated by a light source. Our system is based on a nonnegative image decomposition using a set of possibly ... -
Guided ProceduralModeling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Procedural methods present one of the most powerful techniques for authoring a vast variety of computer graphics models. However, their massive applicability is hindered by the lack of control and a low predictability of ... -
Hatching for Motion Picture Production
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents a hatching algorithm which - while also allows for an implementation in real-time - is integrated into the production pipeline of computer generated motion picture. Motion picture production pipelines ... -
Image and Video Abstraction by Coherence-Enhancing Filtering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In this work, we present a non-photorealistic rendering technique to create stylized abstractions from color images and videos. Our approach is based on adaptive line integral convolution in combination with directional ...
