An Automatic Approach for the Classification of Ancient Clay Statuettes Based on Heads Features Recognition
(The Eurographics Association, 2019)
In recent years, quantitative approaches based on mathematical theories and ICT tools, known under the terms of digital, computational, and virtual archaeology, are more and more involved in the traditional archaeological ...
Towards an Automatic 3D Patterns Classification: the GRAVITATE Use Case
(The Eurographics Association, 2018)
When cataloging archaeological fragments, decorative patterns are an indicator of the stylistic canon an object belongs to. In this paper we address a quantitative classification of the decorative pattern elements that ...
Shape Analysis Techniques for the Ayia Irini Case Study
(The Eurographics Association, 2018)
The typical approach for archaeological analysis is mainly qualitative and, as such, subjective. Even when some measures are reported in the documentation of artefacts, they are often approximate or ambiguous. Conversely, ...
Performing Image-like Convolution on Triangular Meshes
(The Eurographics Association, 2018)
Image convolution with a filtering mask is at the base of several image analysis operations. This is motivated by Mathematical foundations and by the straightforward way the discrete convolution can be computed on a grid-like ...
Pairwise Matching of Stone Tools Based on Flake-Surface Contour Points and Normals
(The Eurographics Association, 2017)
Stone tools constitute the main artifacts facilitating archaeological research of the Paleolithic era. The reassembly of stone tools is the most important research work for analyzing human activities of that period. In ...
Denoising of Point-clouds Based on Structured Dictionary Learning
(The Eurographics Association, 2018)
We formulate the problem of point-cloud denoising in terms of a dictionary learning framework over square surface patches. Assuming that many of the local patches (in the unknown noise-free point-cloud) contain redundancies ...
A Dashboard for the Analysis of Tangible Heritage Artefacts: a Case Study in Archaeology
(The Eurographics Association, 2017)
Digital manipulation and analysis of tangible cultural objects has the potential to bring about a revolution in the way classification, stylistic analysis, and refitting of fragments are handled in the cultural heritage ...
Exploiting Unbroken Surface Congruity for the Acceleration of Fragment Reassembly
(The Eurographics Association, 2017)
Virtual reassembly problems are often encountered in the cultural heritage domain. The reassembly or "puzzling" problem is typically described as the process for the identification of corresponding pieces within a part ...
Completion of Cultural Heritage Objects with Rotational Symmetry
(The Eurographics Association, 2018)
Archaeological artifacts are an important part of our cultural heritage. They help us understand how our ancestors used to live. Unfortunately, many of these objects are badly damaged by the passage of time and need repair. ...
Bone Fracture and Lesion Assessment using Shape-Adaptive Unfolding
(The Eurographics Association, 2017)
The assessment of rib bone fractures and lesions consists of many images that have to be thoroughly inspected slice-by-slice and rib-by-rib. Existing visualization methods, such as curved planar reformation (CPR), reduce ...
