Symmetry in 3D Geometry: Extraction and Applications
(The Eurographics Association, 2012)
The concept of symmetry has received significant attention in computer graphics and computer vision research in recent years. Numerous methods have been proposed to find and extract geometric symmetries and exploit such ...
Interactive Facades - Analysis and Synthesis of Semi-Regular Facades
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Urban facades regularly contain interesting variations due to allowed deformations of repeated elements (e.g., windows in different open or close positions) posing challenges to state-of-the-art facade analysis algorithms. ...
Graph Abstraction for Simplified Proofreading of Slice-based Volume Segmentation
(The Eurographics Association, 2013)
Volume segmentation is an integral data analysis tool in experimental science. For example, in neuroscience, analysis of 3D volumes of neural structures from electron microscopy data is a key analysis step. Despite advances ...
3D Timeline: Reverse Engineering of a Part-based Provenance from Consecutive 3D Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We present a novel tool for reverse engineering of modeling histories from consecutive 3D files based on a timeline abstraction. Although a timeline interface is commonly used in 3D modeling packages for animations, it has ...
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 ...
Structure-Aware Shape Processing
(The Eurographics Association, 2013)
Shape structure is about the arrangement and relations between shape parts. Structure-aware shape processing goes beyond local geometry and low level processing, and analyzes and processes shapes at a high level. It focuses ...
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 ...
Deep Learning for Graphics
(The Eurographics Association, 2018)
In computer graphics, many traditional problems are now better handled by deep-learning based data-driven methods. In applications that operate on regular 2D domains, like image processing and computational photography, ...
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 ...
Repetition Maximization based Texture Rectification
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
Many photographs are taken in perspective. Techniques for rectifying resulting perspective distortions typically rely on the existence of parallel lines in the scene. In scenarios where such parallel lines are hard to ...
