    • Automatic Reconstruction of Virtual Heritage Sites 

      Rodrigues, Nuno; Magalhães, Luís Gonzaga; Moura, João Paulo; Chalmers, Alan (The Eurographics Association, 2008)
      The virtual reconstruction of heritage sites has been the focus of many projects. These typically involve significant use of manual reconstruction techniques, and thus a great deal of human effort to create the virtual ...

    • Automatic Registration and Calibration for Efficient Surface Light Field Acquisition 

      Larue, Frédéric; Dischler, Jean-Michel (The Eurographics Association, 2006)
      This paper presents a novel protocol for the acquisition of surface light fields which is designed to deal with delicate objects that might not be touched or moved. This constraint is particularly important when art pieces ...

    • Automatic Registration for Articulated Shapes 

      Chang, Will; Zwicker, Matthias (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an unsupervised algorithm for aligning a pair of shapes in the presence of significant articulated motion and missing data, while assuming no knowledge of a template, user-placed markers, segmentation, or the ...

    • Automatic Registration of Multi-Projector Domes Using a Single Uncalibrated Camera

      In this paper we present a novel technique for easily calibrating multiple casually aligned projectors on spherical domes using a single uncalibrated camera. Using the prior knowledge of the display surface being a dome, ...

    • Automatic Segmentation of Archaeological Fragments with Relief Patterns using Convolutional Neural Networks 

      Thompson, Elia Moscoso; Ranieri, Andrea; Biasotti, Silvia (The Eurographics Association, 2021)
      The recent commodification of high-quality 3D scanners is leading to the possibility of capturing models of archaeological finds and automatically recognizing their surface reliefs. We present our advancements in this field ...

    • Automatic Segmentation of the Pelvic Bones from CT Data Based on a Statistical Shape Model 

      Seim, Heiko; Kainmueller, Dagmar; Heller, Markus; Lamecker, Hans; Zachow, Stefan; Hege, Hans-Christian (The Eurographics Association, 2008)
      We present an algorithm for automatic segmentation of the human pelvic bones from CT datasets that is based on the application of a statistical shape model. The proposed method is divided into three steps: 1) The averaged ...

    • Automatic Segmentation of Tooth Images: Optimization of Multi-parameter Image Processing Workflow 

      Bressan Fogalli, Giovani; Line, Sérgio Roberto Peres; Baum, Daniel (The Eurographics Association, 2022)
      The development of specific algorithms in image processing are usually related to dataset characteristics. Those characteristics will influence the number of instructions required to solve a problem. Normally, the more ...

    • Automatic Selection of Video Frames for Path Regularization and 3D Reconstruction 

      Pavoni, Gaia; Dellepiane, Matteo; Callieri, Marco; Scopigno, Roberto (The Eurographics Association, 2016)
      Video sequences can be a valuable source to document the state of objects and sites. They are easy to acquire and they usually ensure a complete coverage of the object of interest. One of their possible uses is to recover ...

    • Automatic Semantic-preserving Conversion Between OBJ and CityGML 

      Biljecki, Filip; Arroyo Ohori, Ken (The Eurographics Association, 2015)
      We investigate the automatic conversion between two substantially different formats used in 3D city models: the ubiquitous but semantically poor Wavefront OBJ and the semantically rich but less used OGC standard CityGML. ...

    • Automatic Shader Level of Detail 

      Olano, Marc; Kuehne, Bob; Simmons, Maryann (The Eurographics Association, 2003)
      Current graphics hardware can render procedurally shaded objects in real-time. However, due to resource and performance limitations, interactive shaders can not yet approach the complexity of shaders written for film ...

    • Automatic Shape Expansion with Verification to Improve 3D Retrieval, Classification and Matching 

      Knopp, Jan; Prasad, Mukta; Gool, Luc Van (The Eurographics Association, 2013)
      The goal of this paper is to retrieve 3D object models from a database, that are similar to a single 3D object model, given as a query. The system has no prior models of any object class and is class-generic. The approach ...

    • Automatic Single-View Character Model Reconstruction 

      Buchanan, Philip; Mukundany, R.; Doggett, Michael (ACM, 2013)
      In this paper we present a new method for automatically constructing 3D meshes from a single input image. With the increasing content demands of modern digital entertainment and the expectation of involvement from users, ...

    • Automatic Splicing for Hand and Body Animations 

      Majkowska, Anna; Zordan, Victor B.; Faloutsos, Petros (The Eurographics Association, 2006)
