3D Material Style Transfer
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This work proposes a technique to transfer the material style or mood from a guide source such as an image or video onto a target 3D scene. It formulates the problem as a combinatorial optimization of assigning discrete ... -
Light-Field Retargeting
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a first approach to light-field retargeting using z-stack seam carving, which allows light-field compression and extension while retaining angular consistency. Our algorithm first converts an input light field ... -
Multitouch Gestures for Constrained Transformation of 3D Objects
(The Eurographics Association and John Wiley and Sons Ltd., 2012)3D transformation widgets allow constrained manipulations of 3D objects and are commonly used in many 3D applications for fine-grained manipulations. Since traditional transformation widgets have been mainly designed for ... -
Perceptually Linear Parameter Variations
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Most visual analysis tasks require interactive adjustment of parameter values. In general, a linear variation of a parameter, using for instance a GUI slider, changes the visual result in a perceptually non-linear way. ... -
Automatically Rigging Multi-component Characters
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Rigging an arbitrary 3D character by creating an animation skeleton is a time-consuming process even for experienced animators. In this paper, we present an algorithm that automatically creates animation rigs for multicomponent ... -
Data-Driven Estimation of Cloth Simulation Models
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Progress in cloth simulation for computer animation and apparel design has led to a multitude of deformation models, each with its own way of relating geometry, deformation, and forces. As simulators improve, differences ... -
Procedural Interpolation of Historical City Maps
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose a novel approach for the temporal interpolation of city maps. The input to our algorithm is a sparse set of historical city maps plus optional additional knowledge about construction or destruction events. The ... -
Interactive Multi-perspective Imagery from Photos and Videos
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Photographs usually show a scene from a single perspective. However, as commonly seen in art, scenes and objects can be visualized from multiple perspectives. Making such images manually is time consuming and tedious. We ... -
Computational Design of Rubber Balloons
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This paper presents an automatic process for fabrication-oriented design of custom-shaped rubber balloons. We cast computational balloon design as an inverse problem: given a target shape, we compute an optimal balloon ... -
NoRM: No-Reference Image Quality Metric for Realistic Image Synthesis
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Synthetically generating images and video frames of complex 3D scenes using some photo-realistic rendering software is often prone to artifacts and requires expert knowledge to tune the parameters. The manual work required ... -
SimpleFlow: A Non-iterative, Sublinear Optical Flow Algorithm
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Optical flow is a critical component of video editing applications, e.g. for tasks such as object tracking, segmentation, and selection. In this paper, we propose an optical flow algorithm called SimpleFlow whose running ... -
Real-time Rendering of Dynamic Scenes under All-frequency Lighting using Integral Spherical Gaussian
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose an efficient rendering method for dynamic scenes under all-frequency environmental lighting. To render the surfaces of objects illuminated by distant environmental lighting, the triple product of the lighting, ... -
Interactive Coherence-Based Façade Modeling
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose a novel interactive framework for modeling building façades from images. Our method is based on the notion of coherence-based editing which allows exploiting partial symmetries across the façade at any level of ... -
Data Driven Surface Reflectance from Sparse and Irregular Samples
(The Eurographics Association and John Wiley and Sons Ltd., 2012)In recent years, measuring surface reflectance has become an established method for high quality renderings. In this context, especially non-parametric representations got a lot of attention as they allow for a very accurate ... -
Creating Picture Legends for Group Photos
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Group photos are one of the most common types of digital images found in personal image collections and on social networks. One typical post-processing task for group photos is to produce a key or legend to identify the ... -
A GPU-based Approach for Massive Model Rendering with Frame-to-Frame Coherence
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Rendering massive 3D models in real-time has long been recognized as a very challenging problem because of the limited computational power and memory space available in a workstation. Most existing rendering techniques, ... -
Factored Facade Acquisition using Symmetric Line Arrangements
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce a novel framework for image-based 3D reconstruction of urban buildings based on symmetry priors. Starting from image-level edges, we generate a sparse and approximate set of consistent 3D lines. These lines ... -
Advected Tangent Curves: A General Scheme for Characteristic Curves of Flow Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present the first general scheme to describe all four types of characteristic curves of flow fields - stream, path, streak, and time lines - as tangent curves of a derived vector field. Thus, all these lines can be ... -
A Computational Model of Afterimages
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Afterimages are optical illusions, particularly well perceived when fixating an image for an extended period of time and then looking at a neutral background, where an inverted copy of the original stimulus appears. The ... -
