Using 3D Scanning to Analyze a Proposal for the Attribution of a Bronze Horse to Leonardo da Vinci
(The Eurographics Association, 2007)
In this paper we present how technologies developed in the context of 3D graphics (3D scanning and image-to- 3D-model mapping) have been used to evaluate in a metrically objective way the plausibility of an attribution ...
Artifacts Removal for Color Projection on 3D Models using Flash Light
(The Eurographics Association, 2009)
Abstract Lighting artifacts are one of the main issues in digital photography: complex light setups are needed to attenuate or remove them. Flash light is a very easy way to illuminate an object or an environment, but it ...
Alchemy in 3D - A Digitization for a Journey Through Matter
(IEEE, 2015)
In this work, we will present the outcomes of the 3D diagnostic investigations carried out on the painting Alchemy by Jackson Pollock. Thanks to an accurate digitization and a careful processing, we were able to generate ...
Documentation and Interpretation of an Archeological Excavation: an Experience with Dense Stereo Reconstruction Tools
(The Eurographics Association, 2011)
An archeological excavation is usually a rapidly evolving environment: several factors (weather, costs, permissions) force the work to be concentrated in a few weeks. Moreover, excavating is essentially a mono-directional ...
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 ...
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, ...
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 ...
Digital Fabrication Technologies for Cultural Heritage (STAR)
(The Eurographics Association, 2014)
Digital Fabrication technologies exploit a variety of basic technologies to create tangible reproductions of 3D digital models. Even though current 3D printing pipelines still suffer of several restrictions, the reproduction ...
