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 ...
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 ...
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. ...
Virtual Restoration of Wooden Artifacts by Non-Rigid 3D Shape Assembly: A Case of the First Solar Boat of King Khufu
(The Eurographics Association, 2018)
In this paper, we present a method to digitally reassemble an object to its original form given the 3D data of its component which are assumed to be non-rigidly deformed. Targeting wooden artifacts, we developed an algorithm ...
Visual Assessment of Vascular Torsion using Ellipse Fitting
(The Eurographics Association, 2018)
Blood vessels are well explored and researched in medicine and visualization. However, the investigation of vascular torsion has yet been unexplored. In order to understand the development and current state of a single ...
