    • Unsupervised Three-dimensional Reconstruction of Small Rocks from a Single Two-dimensional Image 

      Gilardi, Marco; Watten, Phil L.; Newbury, Paul (The Eurographics Association, 2014)
      Surfaces covered with pebbles and small rocks can often be found in nature or in human-shaped environments. Generating an accurate three-dimensional model of these kind of surfaces from a reference image can be challenging, ...

    • HDR Reconstruction for Alternating Gain (ISO) Sensor Readout 

      Hajisharif, Saghi; Kronander, Joel; Unger, Jonas (The Eurographics Association, 2014)
      Modern image sensors are becoming more and more flexible in the way an image is captured. In this paper, we focus on sensors that allow the per pixel gain to be varied over the sensor and develop a new technique for efficient ...

    • Unified Skeletal Animation Reconstruction with Multiple Kinects 

      Ahmed, Naveed (The Eurographics Association, 2014)
      We present a new method for reconstructing a unified skeletal animation with multiple Kinects. Our method is able to reconstruct the unified skeletal animation from Kinect data over 360 degrees. We make use of all three ...

    • Depth Sensor-Based Realtime Tumor Tracking for Accurate Radiation Therapy 

      Nutti, Björn; Kronander, Åsa; Nilsing, Mattias; Maad, Kristofer; Svensson, Cristina; Li, Hao (The Eurographics Association, 2014)
      We present an image guided radiation therapy (IGRT) system for tracking tumors in realtime based on continuous structured light imaging. While an accurate positioning of the radiation isocenter to pre-imaged cancer cells ...

    • Reconstructing Complex Indoor Environments with Arbitrary Wall Orientations 

      Mura, Claudio; Villanueva, Alberto Jaspe; Mattausch, Oliver; Gobbetti, Enrico; Pajarola, Renato (The Eurographics Association, 2014)
      Reconstructing the architectural shape of interiors is a problem that is gaining increasing attention in the field of computer graphics. Some solutions have been proposed in recent years, but cluttered environments with ...

    • Skeleton-based Joints Position Detection 

      Madaras, Martin; Piovarci, Michal; Kovacovský, Tomás (The Eurographics Association, 2014)
      We present a system for detection of joint positions in scans of articulated models. Our method is based purely on skeletons extracted from scanned point clouds of input models. First, skeletons are extracted from scans ...

    • Hexahedral Mesh Adaptation to Imprint Geometric Details: Application to CAD Models 

      Goff, Nicolas Le; Ledoux, Franck; Weill, Jean-Christophe (The Eurographics Association, 2014)
      A novel algorithm is proposed to modify any unstructured hexahedral mesh in order to diminish the global time of numerical simulation processes, like optimization process and parametric studies. It consists in an imprinting ...

    • The Split Grid - A Hierarchical 1D-Grid-based Acceleration Data Structure for Ray Tracing 

      Bauszat, Pablo; Kastner, Marc Aurel; Eisemann, Martin; Magnor, Marcus (The Eurographics Association, 2014)
      We present a new acceleration structure for ray tracing called the Split Grid. Combining concepts of hierarchical grids, kd-trees and Bounding Volume Hierarchies (BVHs), our approach is based on the idea of nesting 1D-grids. ...
