Jointly Optimized Regressors for Image Super-resolution
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Learning regressors from low-resolution patches to high-resolution patches has shown promising results for image super-resolution. We observe that some regressors are better at dealing with certain cases, and others with ... -
Layer-Based Procedural Design of Façades
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel procedural framework for interactively modeling building façades. Common procedural approaches, such as shape grammars, assume that building façades are organized in a tree structure, while in practice ... -
Light Chisel: 6DOF Pen Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel interaction device tracked in 6 degrees of freedom by two commodity cameras. The inexpensive Light Chisel is statically illuminated with two LEDs, and uses no additional sensor (e.g. inertial or magnetic) ... -
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 ...
