    • Guided Capturing of Multi-view Stereo Datasets 

      Langguth, Fabian; Goesele, Michael (The Eurographics Association, 2013)
      We present an application for mobile devices, that allows any user, even without background in computer vision, to capture a complete set of images, that is suitable for a multi-view stereo reconstruction. Compared to ...

    • Automatic Modeling of Planar-Hinged Buildings 

      Garcia-Dorado, Ignacio; Aliaga, Daniel G. (The Eurographics Association, 2013)
      We present a framework to automatically model and reconstruct buildings in a dense urban area. Our method is robust to noise and recovers planar features and sharp edges, producing a water-tight triangulation suitable for ...

    • GPU Roof Grammars 

      Buron, Cyprien; Marvie, Jean-Eudes; Gautron, Pascal (The Eurographics Association, 2013)
      We extend GPU shape grammars [MBG12] to model highly detailed roofs. Starting from a consistent roof structure such as a straight skeleton computed from the building footprints, we decompose this information into local ...

    • Automatic Generation of Constructable Brick Sculptures 

      Testuz, Romain; Schwartzburg, Yuliy; Pauly, Mark (The Eurographics Association, 2013)
      Fabrication of LEGO R models in large scale requires careful pre-planning to produce constructable and stable models. We propose a system that, starting with a voxelization of a 3D mesh, merges voxels to form larger bricks, ...

    • Graph Abstraction for Simplified Proofreading of Slice-based Volume Segmentation 

      Sicat, Ronell B.; Hadwiger, Markus; Mitra, Niloy J. (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 ...

    • Size-Based Rendering for Lung Cancer Screening 

      Wiemker, Rafael; Bülow, Thomas; Klinder, Tobias (The Eurographics Association, 2013)
      We present two relevant clinical use cases for thoracic computed tomography data, where the recently introduced concept of size-based rendering can be beneficially applied to medical visualization in the context of screening ...

    • Real-Time Importance Sampling of Dynamic Environment Maps 

      Lu, Heqi; Pacanowski, Romain; Granier, Xavier (The Eurographics Association, 2013)
      We introduce a simple and effective technique for light-based importance sampling of dynamic environment maps based on the formalism of Multiple Importance Sampling (MIS). The core idea is to balance per pixel the number ...

    • Extraction and Visual Analysis of Seismic Horizon Ensembles 

      Höllt, Thomas; Chen, Guoning; Hansen, Charles D.; Hadwiger, Markus (The Eurographics Association, 2013)
      Seismic interpretation is an important step in building subsurface models, which are needed to efficiently exploit fossil fuel reservoirs. However, seismic features are seldom unambiguous, resulting in a high degree of ...

    • Perceptually Motivated Real-Time Compression of Motion Data Enhanced by Incremental Encoding and Parameter Tuning 

      Firouzmanesh, Amirhossein; Cheng, Irene; Basu, Anup (The Eurographics Association, 2013)
      We address the problem of efficient real-time motion data compression considering human perception. Using incremental encoding plus a database of motion primitives for each key point, our method achieves a higher or ...

    • Real-Time Image-Based Volume Lighting 

      Delalandre, Cyril; Gautron, Pascal; Marvie, Jean-Eudes (The Eurographics Association, 2013)
      The interaction of translucent objects with light creates complex effects such as scattering, absorption and volumetric shadows. While most accurate rendering approaches resort to heavy computations, recent needs in ...

    • Automatic Parameter Control for Metropolis Light Transport 

      Zsolnai, Károly; Szirmay-Kalos, László (The Eurographics Association, 2013)
      Sophisticated global illumination algorithms usually have several control parameters that need to be set appropriately in order to obtain high performance and accuracy. Unfortunately, the optimal values of these parameters ...

    • Seam-Driven Image Stitching 

      Gao, Junhong; Li, Yu; Chin, Tat-Jun; Brown, Michael S. (The Eurographics Association, 2013)
      Image stitching computes geometric transforms to align images based on the best fit of feature correspondences between overlapping images. Seam-cutting is used afterwards to to hide misalignment artifacts. Interestingly ...

    • Generating Pseudo-3D Painting Based on Visual Saliency and Composition Rules 

      Zheng, Zhibin; Zhang, Yan; Sun, Zhengxing (The Eurographics Association, 2013)
      Pseudo-3D painting shows stereoscopic artistic effect in the 2D plane and displays artistic conception as the known verse "Far, near, high, low-no two parts alike", it brings a true feeling of stereo space to observers. ...

    • Accelerating kd-tree Searches for all k-nearest Neighbours 

      Merry, Bruce; Gain, James; Marais, Patrick (The Eurographics Association, 2013)
      Finding the k nearest neighbours of each point in a point cloud forms an integral part of many point-cloud processing tasks. One common approach is to build a kd-tree over the points and then iteratively query the k nearest ...

    • Real-time Collision Detection for Dynamic Hardware Tessellated Objects 

      Nießner, Matthias; Siegl, Christian; Schäfer, Henry; Loop, Charles (The Eurographics Association, 2013)
      We present a novel method for real-time collision detection of patch based, displacement mapped objects using hardware tessellation. Our method supports fully animated, dynamically tessellated objects and runs entirely on ...
