Object Detection and Classification from Large-Scale Cluttered Indoor Scans
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a method to automatically segment indoor scenes by detecting repeated objects. Our algorithm scales to datasets with 198 million points and does not require any training data. We propose a trivially parallelizable ... -
On-line Real-time Physics-based Predictive Motion Control with Balance Recovery
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present an on-line real-time physics-based approach to motion control with contact repositioning based on a low-dimensional dynamics model using example motion data. Our approach first generates a reference ... -
On-the-fly Generation and Rendering of Infinite Cities on the GPU
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present a new approach for shape-grammar-based generation and rendering of huge cities in real-time on the graphics processing unit (GPU). Traditional approaches rely on evaluating a shape grammar and ... -
Optimizing BRDF Orientations for the Manipulation of Anisotropic Highlights
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper introduces a system for the direct editing of highlights produced by anisotropic BRDFs, which we call anisotropic highlights. We first provide a comprehensive analysis of the link between the direction of ... -
Optimizing Stereo-to-Multiview Conversion for Autostereoscopic Displays
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel stereo-to-multiview video conversion method for glasses-free multiview displays. Different from previous stereo-to-multiview approaches, our mapping algorithm utilizes the limited depth range of ... -
Panorama Light-Field Imaging
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel approach to recording and computing panorama light fields. In contrast to previous methods that estimate panorama light fields from focal stacks or naive multi-perspective image stitching, our approach ... -
Parallel Generation of Architecture on the GPU
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present a novel approach for the parallel evaluation of procedural shape grammars on the graphics processing unit (GPU). Unlike previous approaches that are either limited in the kind of shapes they allow, ... -
Parameter Estimation and Comparative Evaluation of Crowd Simulations
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel framework to evaluate multi-agent crowd simulation algorithms based on real-world observations of crowd movements. A key aspect of our approach is to enable fair comparisons by automatically estimating ... -
Pathline Glyphs
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Visualization of pathlines is common and highly relevant for the analysis of unsteady flow. However, pathlines can intersect, leading to visual clutter and perceptual issues. This makes it intrinsically difficult to provide ... -
Perceptual Depth Compression for Stereo Applications
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Conventional depth video compression uses video codecs designed for color images. Given the performance of current encoding standards, this solution seems efficient. However, such an approach suffers from many issues ... -
Pose Partitioning for Multi-resolution Segmentation of Arbitrary Mesh Animations
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a complete approach to efficiently deriving a varying level-of-detail segmentation of arbitrary animated objects. An over-segmentation is built by combining sets of initial segments computed for each input pose, ... -

A Randomized Algorithm for Natural Object Colorization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Natural objects often contain vivid color distribution with wide variety of colors. Conventional colorization techniques, on the other hand, produce colors that are relatively flat with little color variation. In this ... -
Rate-distortion Optimized Compression of Motion Capture Data
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Lossy compression of motion capture data can alleviate the problems of efficient storage and transmission by exploiting the redundancy and the superfluous precision of the data. When considering the acceptable amount of ... -
Recurring Part Arrangements in Shape Collections
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Extracting semantically related parts across models remains challenging, especially without supervision. The common approach is to co-analyze a model collection, while assuming the existence of descriptive geometric features ... -
SAFE: Structure-aware Facade Editing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Many man-made objects, in particular building facades, exhibit dominant structural relations such as symmetry and regularity. When editing these shapes, a common objective is to preserve these relations. However, often ... -
Self-similarity for Accurate Compression of Point Sampled Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Most surfaces, be it from a fine-art artifact or a mechanical object, are characterized by a strong self-similarity. This property finds its source in the natural structures of objects but also in the fabrication processes: ... -
ShapeSynth: Parameterizing Model Collections for Coupled Shape Exploration and Synthesis
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Recent advances in modeling tools enable non-expert users to synthesize novel shapes by assembling parts extracted from model databases. A major challenge for these tools is to provide users with relevant parts, which is ... -
SimSelect: Similarity-based Selection for 3D Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Surface selection is one of the fundamental interactions in shape modeling. In the case of complex models, this task is often tedious for at least two reasons: firstly the local geometry of a given region may be hard to ... -
Spatio-Temporal Geometry Fusion for Multiple Hybrid Cameras using Moving Least Squares Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Multi-view reconstruction aims at computing the geometry of a scene observed by a set of cameras. Accurate 3D reconstruction of dynamic scenes is a key component for a large variety of applications, ranging from special ...
