      The creation of 3D models of heritage and architectural sites requires proper technologies able to capture a wide area at fine geometric and appearance detail. In this paper we address the acquisition and digitization of ...

    • An Image Recognition System of Aboriginal Artefact for Knowledge Sharing using Machine Learning 

      Ma, Yajun; Karim, Asif; Haque, A. S. M. Farhan Al (The Eurographics Association, 2022)
      Acquiring knowledge about indigenous artefacts is difficult without prior experience. Due to the scarcity of digitally preserved artefacts, the new online generations are not exposed to even the most basic concepts. This ...

    • Scan2FEM: From Point Clouds to Structured 3D Models Suitable for Simulation 

      Selman, Zain; Musto, Juan; Kobbelt, Leif (The Eurographics Association, 2022)
      Preservation of cultural heritage is important to prevent singular objects or sites of cultural importance to decay. One aspect of preservation is the creation of a digital twin. In case of a catastrophic event, this twin ...

    • A Concept for Reconstructing Stucco Statues from historic Sketches using synthetic Data only 

      Pöllabauer, Thomas; Kühn, Julius (The Eurographics Association, 2022)
      In medieval times, stuccoworkers used a red color, called sinopia, to first create a sketch of the to-be-made statue on the wall. Today, many of these statues are destroyed, but using the original drawings, deriving from ...

    • GCH 2022: Frontmatter 

      Ponchio, Federico; Pintus, Ruggero (The Eurographics Association, 2022)

    • A Course on the Digital Humanities for the Premodern World 

      Rushmeier, Holly; Chen, Anne (The Eurographics Association, 2022)
      With the roots of digital humanities in text-centric disciplines, coursework has traditionally focused on instruction in skills of relevance for text-based resources, while digital methods for non-textual sources have ...

    • Context-based Surface Pattern Completion of Ancient Pottery 

      Lengauer, Stefan; Preiner, Reinhold; Sipiran, Ivan; Karl, Stephan; Trinkl, Elisabeth; Bustos, Benjamin; Schreck, Tobias (The Eurographics Association, 2022)
      Among various ancient cultures it was common practice to adorn pottery artifacts with lavish surface decoration. While the applied painting styles, color schemes and displayed mythological content may vary greatly, the ...
