Digital Study and Web-based Documentation of the Colour and Gilding on Ancient Marble Artworks
(IEEE, 2015)
Greek and Roman marble artworks have been deeply studied from a typological and stylistic point of view, while there is still a limited knowledge on the pigments, dyes, binders and technical expedients used by Roman artists. ...
Pushing Time-of-Flight Scanners to the Limit
(The Eurographics Association, 2009)
The paper describes a pipeline for 3D scanning acquisition and processing that allow to exploit the utmost precision and quality out of ToF scanners. The proposed approach capitalize on the knowledge of the distribution ...
Interactive Remote Exploration of Massive Cityscapes
(The Eurographics Association, 2009)
We focus on developing a simple and efficient unified level-of-detail structure for networked urban model viewers. At the core of our approach is a revisitation of the BlockMap [CDG*07] data structure, originally introduced ...
From Paper to Web: Automatic Generation of a Web-Accessible 3D Repository of Pottery Types
(The Eurographics Association, 2017)
3D web repositories are a hot topic for the research community in general. In the Cultural Heritage (CH) context, 3D repositories pose a difficult challenge due to the complexity and variability of models and to the need ...
High Quality PTM Acquisition: Reflection Transformation Imaging for Large Objects
(The Eurographics Association, 2006)
Reflection Transformation Imaging has proved to be a powerful method to acquire and represent the 3D reflectance properties of an object, displaying them as a 2D image. Recently, Polynomial Texture Maps (PTM), which are ...
Removing Shadows for Color Projection Using Sun Position Estimation
(The Eurographics Association, 2010)
The result of an outdoors 3D scanning acquisition campaign is usually an accurate 3D model of the site, but in most of the cases the quality of the color acquired by the scanner is not satisfying. Alternative solutions, ...
Verification and Acceptance Tests for High Definition 3D Surface Scanners
(The Eurographics Association, 2010)
High definition three-dimensional (3D) surface scanners, based on structured light or laser light section techniques, have found a wide range of applications, especially for technical and industrial applications (mostly ...
A computer-assisted constraint-based system for assembling fragmented objects
(The Eurographics Association, 2013)
We propose a computer-assisted constraint-based methodology for virtual reassembly of Cultural Heritage (CH) artworks. Instead than focusing on automatic, unassisted reassembly, we targeted the scenarios where the ...
Surface Light Field from Video Acquired in Uncontrolled Settings
(The Eurographics Association, 2013)
This paper presents an algorithm for the estimation of the Surface Light Field using video sequences acquired moving the camera around the object. Unlike other state of the art methods, it does not require a uniform sampling ...
Global refinement of image-to-geometry registration for color projection on 3D models
(The Eurographics Association, 2013)
The management, processing and visualization of color information is a critical subject in the context of the acquisition and visualization of real objects. Especially in the context of Cultural Heritage, artifacts are so ...
