SynthPS: a Benchmark for Evaluation of Photometric Stereo Algorithms for Cultural Heritage Applications
(The Eurographics Association, 2020)
Photometric Stereo (PS) is a technique for estimating surface normals from a collection of images captured from a fixed viewpoint and with variable lighting. Over the years, several methods have been proposed for the task, ...
Anatomy Changes and Virtual Restoration of Statues
(The Eurographics Association, 2020)
Restoration of archaeological artefacts is an important task for cultural heritage preservation. However traditional restoration processes are difficult, costly and sometimes risky for the artefact itself, due to poor ...
Another Brick in the Wall: Improving the Assisted Semantic Segmentation of Masonry Walls
(The Eurographics Association, 2020)
In Architectural Heritage, the masonry's interpretation is an essential instrument for analyzing the construction phases, the assessment of structural properties, and the monitoring of its state of conservation. This work ...
Semi-automated Annotation of Repetitive Ornaments on 3D Painted Pottery Surfaces
(The Eurographics Association, 2020)
The creation of drawings from the surface of painted pottery artifacts is an important practice in archaeological research and documentation. Traditional approaches include manual drawings using pen and paper, either ...
Interaction with 3D Models on Virtual Archaeological Sites
(The Eurographics Association, 2020)
The extraction of artifacts during the excavation of an archaeological site usually implies the loss of spatial references among the extracted vestiges. In this work we introduce a way to compute spatial relationships among ...
Traditional-based Visualization Methods for Archaeological 3D Data: an Evaluation
(The Eurographics Association, 2020)
3D archaeological visualization is an increasingly frequent and necessary practice, but it still faces application issues. Those are substantiated by the use of visualization tools that are not customized for the archaeological ...
GCH 2020: Frontmatter
(The Eurographics Association, 2020)
Automatic Segmentation of Archaeological Fragments with Relief Patterns using Convolutional Neural Networks
(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 ...
Exploiting Neighboring Pixels Similarity for Effective SV-BRDF Reconstruction from Sparse MLICs
(The Eurographics Association, 2021)
We present a practical solution to create a relightable model from Multi-light Image Collections (MLICs) acquired using standard acquisition pipelines. The approach targets the difficult but very common situation in which ...
Riedones3D: a Celtic Coin Dataset for Registration and Fine-grained Clustering
(The Eurographics Association, 2021)
Clustering coins with respect to their die is an important component of numismatic research and crucial for understanding the economic history of tribes (especially when literary production does not exist, in celtic culture). ...
