The Role of Similarity in the Re-unification, Re-assembly and Re-association of 3D ArtefactsMichela Spagnuolo and Bianca Falcidieno
Digital manipulation and analysis of tangible cultural objects has the potential to bring about a revolution in the way classification, stylistic analysis, or refitting of fragments is handled in the cultural heritage area: 3D modelling, processing and analysis are now mature enough to allow handling 3D digitized objects as if they were physical, and semantic models allow for a rich documentation of many different aspects of artefacts or assets of any complexity, as well as of contextual information about them.
In this context, the workshop was promoted by the recently started EC project GRAVITATE with the aim of bringing together researchers and professionals in Cultural Heritage contributing their perspective on the impact of digital techniques on re-unification, re-assembly and re-association of fragmented or dispersed cultural assets. Similarity evaluation is underlying most of these challenges. Comparative reasoning on artefacts and artifact's properties may relate to geometric attributes (e.g., spatial extent, aspect), to colorimetric properties (e.g., colour, texture), to specific traits that fragments exhibit (e.g., decorations), or to metadata documenting the artefacts. The workshop programme will give an overview of how computational similarity is addressed by ongoing research activities and European projects, and how it can be used at the geometric and semantic level for artefact and fragment analysis, supported by advanced digitalization techniques.
The workshop programme can be of interest for scientists and CH professionals and curators, who could learn about the recent developments in the field of shape analysis and semantic description of 3D digital artefacts and contribute to the discussion with their own experience.
