Digital Heritage 2015

INSIDDE: Integration of Technological Solutions for Imaging, Detection, and Digitisation of hidden Elements in Artworks
Marta Flórez Igual and Hamdi Dibeklioğlu

This workshop is intended to give an overview about the capabilities of terahertz (THz) waves in the field of cultural heritage and make a comparison with other technologies such as infrared (IR) reflectography or optical coherence tomography (OCT). In this workshop, different cases dealing with 2D and 3D artworks will be presented.

The target audience of this workshop covers a wide range of profiles, from art experts to scientific researchers in different areas. Although an overview of the technologies will be given, speakers will mainly concentrate on the applications in the field of cultural heritage and the requirements to take advantage of the latest developments.

The workshop is also understood as a co-operative environment to foster collaborations between end-users and researchers. Therefore, a close interaction with the attendees is expected during the discussions but also during the presentations. This will limit the number of attendees to 20-25 people.

 Agenda
