Optimal Spline Approximation via l0-Minimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Splines are part of the standard toolbox for the approximation of functions and curves in Rd. Still, the problem of finding the spline that best approximates an input function or curve is ill-posed, since in general this ... -
Paint and Click: Unified Interactions for Image Boundaries
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Image boundaries are a fundamental component of many interactive digital photography techniques, enabling applications such as segmentation, panoramas, and seamless image composition. Interactions for image boundaries often ... -
Panoramic Video from Unstructured Camera Arrays
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We describe an algorithm for generating panoramic video from unstructured camera arrays. Artifact-free panorama stitching is impeded by parallax between input views. Common strategies such as multi-level blending or minimum ... -
Parallel, Realistic and Controllable Terrain Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2015)The challenge in terrain synthesis for virtual environments is to provide a combination of precise user control over landscape form, with interactive response and visually realistic results. We present a system that builds ... -
Partitioned Shadow Volumes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Real-time shadows remain a challenging problem in computer graphics. In this context, shadow algorithms generally rely either on shadow mapping or shadow volumes. This paper rediscovers an old class of algorithms that build ... -
Real-Time Subspace Integration for Example-Based Elastic Material
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Example-based material allows simulating complex material behaviors in an art-directed way. This paper presents a method for fast subspace integration for example-based elastic material, which is suitable for real-time ... -
Replaceable Substructures for Efficient Part-Based Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2015)A popular mode of shape synthesis involves mixing and matching parts from different objects to form a coherent whole. The key challenge is to efficiently synthesize shape variations that are plausible, both locally and ... -
Rich-VPLs for Improving the Versatility of Many-Light Methods
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Many-light methods approximate the light transport in a scene by computing the direct illumination from many virtual point light sources (VPLs), and render low-noise images covering a wide range of performance and quality ... -
Robust Statistical Pixel Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Robust statistical methods are employed to reduce the noise in Monte Carlo ray tracing. Through the use of resampling, the sample mean distribution is determined for each pixel. Because this distribution is uni-modal and ... -
Sample Elimination for Generating Poisson Disk Sample Sets
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper we describe sample elimination for generating Poisson disk sample sets with a desired size. We introduce a greedy sample elimination algorithm that assigns a weight to each sample in a given set and eliminates ... -
Scalable Partitioning for Parallel Position Based Dynamics
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce a practical partitioning technique designed for parallelizing Position Based Dynamics, and exploiting the ubiquitous multi-core processors present in current commodity GPUs. The input is a set of particles ... -
Selective Degree Elevation for Multi-Sided Bézier Patches
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper presents a method to selectively elevate the degree of an S-Patch of arbitrary dimension. We consider not only S-Patches with 2D domains but 3D and higher-dimensional domains as well, of which volumetric cage ... -
Self Tuning Texture Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)The goal of example-based texture synthesis methods is to generate arbitrarily large textures from limited exemplars in order to fit the exact dimensions and resolution required for a specific modeling task. The challenge ... -
Shape-from-Operator: Recovering Shapes from Intrinsic Operators
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We formulate the problem of shape-from-operator (SfO), recovering an embedding of a mesh from intrinsic operators defined through the discrete metric (edge lengths). Particularly interesting instances of our SfO problem ... -
Skeleton-Intrinsic Symmetrization of Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Enhancing the self-symmetry of a shape is of fundamental aesthetic virtue. In this paper, we are interested in recovering the aesthetics of intrinsic reflection symmetries, where an asymmetric shape is symmetrized while ... -
SmartAnnotator: An Interactive Tool for Annotating Indoor RGBD Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)RGBD images with high quality annotations, both in the form of geometric (i.e., segmentation) and structural (i.e., how do the segments mutually relate in 3D) information, provide valuable priors for a diverse range of ... -
Statics Aware Grid Shells
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce a framework for the generation of polygonal grid-shell architectural structures, whose topology is designed in order to excel in static performances. We start from the analysis of stress on the input surface ... -
T-SAH: Animation Optimized Bounding Volume Hierarchies
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a method for creating a bounding volume hierarchy (BVH) that is optimized for all frames of a given animated scene. The method is based on a novel extension of surface area heuristic to temporal domain (T-SAH). ... -
Template Assembly for Detailed Urban Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a new framework to reconstruct building details by automatically assembling 3D templates on coarse textured building models. In a preprocessing step, we generate an initial coarse model to approximate a point ... -
VDub: Modifying Face Video of Actors for Plausible Visual Alignment to a Dubbed Audio Track
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In many countries, foreign movies and TV productions are dubbed, i.e., the original voice of an actor is replaced with a translation that is spoken by a dubbing actor in the country's own language. Dubbing is a complex ...
