EUROGRAPHICS 2015: CGF 34-2 Frontmatter
(The Eurographics Association and John Wiley & Sons Ltd., 2015) -
General and Robust Error Estimation and Reconstruction for Monte Carlo Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Adaptive filtering techniques have proven successful in handling non-uniform noise in Monte-Carlo rendering approaches. A recent trend is to choose an optimal filter per pixel from a selection of non spatially-varying ... -
Generating Design Suggestions under Tight Constraints with Gradient-based Probabilistic Programming
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a system for generating suggestions from highly-constrained, continuous design spaces. We formulate suggestion as sampling from a probability distribution; constraints are represented as factors that concentrate ... -
Guiding Image Manipulations using Shape-appearance Subspaces from Co-alignment of Image Collections
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a system to restrict the manipulation of shape and appearance in an image to a valid subspace which we learn from a collection of exemplar images. To this end, we automatically co-align a collection of images ... -
Hallucinating Stereoscopy from a Single Image
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce a novel method for enabling stereoscopic viewing of a scene from a single pre-segmented image. Rather than attempting full 3D reconstruction or accurate depth map recovery, we hallucinate a rough approximation ... -
Hardware-Based Non-Photorealistic Rendering Using a Painting Robot
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We describe a painting machine and associated algorithms. Our modified industrial robot works with visual feedback and applies acrylic paint from a repository to a canvas until the created painting resembles a given input ... -
High Reliefs from 3D Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a method for synthesizing high reliefs, a sculpting technique that attaches 3D objects onto a 2D surface within a limited depth range. The main challenges are the preservation of distinct scene parts by preserving ... -
High-Order Recursive Filtering of Non-Uniformly Sampled Signals for Image and Video Processing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a discrete-time mathematical formulation for applying recursive digital filters to non-uniformly sampled signals. Our solution presents several desirable features: it preserves the stability of the original ... -
IlluminationCut
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel algorithm, IlluminationCut, for rendering images using the many-lights framework. It handles any light source that can be approximated with virtual point lights (VPLs) as well as highly glossy materials. ... -
Implicit Formulation for SPH-based Viscous Fluids
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a stable and efficient particle-based method for simulating highly viscous fluids that can generate coiling and buckling phenomena and handle variable viscosity. In contrast to previous methods that use explicit ... -
Improving Sampling-based Motion Control
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We address several limitations of the sampling-based motion control method of Liu et at. [LYvdP 10]. The key insight is to learn from the past control reconstruction trials through sample distribution adaptation. Coupled ... -
Interactive Dimensioning of Parametric Models
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a solution for the dimensioning of parametric and procedural models. Dimensioning has long been a staple of technical drawings, and we present the first solution for interactive dimensioning: a dimension line ... -
Interactive Disassembly Planning for Complex Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an approach for the automatic generation, interactive exploration and real-time modification of disassembly procedures for complex, multipartite CAD data sets. In order to lift the performance barriers prohibiting ... -
Interactive Generation of Realistic Facial Wrinkles from Sketchy Drawings
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Synthesizing facial wrinkles has been tackled either by a long process of manual sculpting on 3D models, or using automatic methods that do not allow for user interaction or artistic expression. In this paper, we propose ... -
IsoMatch: Creating Informative Grid Layouts
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Collections of objects such as images are often presented visually in a grid because it is a compact representation that lends itself well for search and exploration. Most grid layouts are sorted using very basic criteria, ... -
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 ...
