This paper describes a computer-aided method for the reconstruction and modelling of complex sites based on content-based indexing of images. A pose, distortion and composition robust descriptor is automatically generated for each image associated with a given site. These descriptors are subsequently placed in a database, to be used for future querying. The database is interrogated in real-time...

Can one of the most important Italian Renaissance frescoes reduced in hundreds of thousand fragments by a bombing during the Second World War be re-composed after more than 60 years from its damage? Can we reconstruct the missing parts and can we say something about their original color? In this short paper we want to exemplify, hopefully effectively by taking advantage of the seduction of art,...

This paper presents an original two-step procedure for estimating projective transformations between pairs of images: first, the transformation between the images is approximated as an affine transformation; second, this estimate is refined into that of a projective transformation. This strategy for matching projective views is computationally very efficient. The proposed method can be applied ...

BACKGROUND A microclimate monitoring study was conducted in 2008 aimed at assessing the conservation risks affecting the valuable wall paintings decorating Ariadne's House (Pompeii, Italy). It was found that thermohygrometric conditions were very unfavorable for the conservation of frescoes. As a result, it was decided to implement corrective measures, and the transparent polycarbonate sheets c...

A typo has been found in our paper [1]. It is stated on page 8698 that the range of acceptable temperature for the conservation of frescoes is 6–25 °C while in the case of RH, this range is 45%–60%, according to the Italian Standard UNI 10829 (1999). These recommended ranges of temperature (6–25 °C) and RH (45%–60%) correspond to the Standard DM 10/2001 [2], not to UNI 10829. The authors would ...

Microbial agents are among the major causes of deterioration of cultural heritage, strongly affecting our global cultural legacy, the stone, glass, wood and other sources used to fabricate millions of artworks and monuments around the world. However, it is not all about rotting and erosion! Microbial action has been harnessed to clean the surfaces of stone sculptures and buildings and frescoes....
