VPL FOR CULTURAL HERITAGE MONITORING: SAMPLING AND COMPARISON OF PHOTOGRAPHIC IMAGES

Abstract

In the last decades, ICT strongly support cultural heritage conservation, management, valorisation and communication activities. Digital systems record series of data in real time, facilitating the automation of comparison, control and preventive evaluation activities aimed at the conscious management of the phenomenal reality based on the interrelationship between different information. According to these premises, this contribution presents first results of a research activity aimed at testing VPL parametric tools aimed at mapping environmental data and phenomena involving architectural surfaces and explicitating the comparison between data by graphical alert system. VPL tools are designed for a thematic image colour sampling. The main goal is monitoring the state of conservation of decorated architectural surfaces or artworks placed in unfavourable environmental conditions to facilitate preventive and intervention activities. The case study chosen to test this approach and digital tools is the fresco preserved in the Filangieri Hall of the State Archives in Naples.
