Acquisition strategies for in-situ hyperspectral imaging of stained-glass windows: case studies from the Swiss National Museum
(Peer reviewed; Journal article, 2023)Over the last decade, hyperspectral imaging has become a popular technique for the non-invasive identification and mapping of painting materials in many typologies of artworks, thanks to the possibility of obtaining spectral ... -
Appearance-based evaluation of varnish removal methods in gilded surfaces
(Peer reviewed; Journal article, 2023)This paper outlines the use of bidirectional reflectance measurements for the characterisation and evaluation of appearance changes in gilded surfaces caused by varnishing and cleaning. Oil and water gilding mock-ups ... -
But aren’t all soaps metal soaps? A review of applications, physico-chemical properties of metal soaps and their occurrence in cultural heritage studies
(Peer reviewed; Journal article, 2023)Metal soaps, the organic salts resulting from the interaction of fatty acids and metal cations, arouse interest in the scientific field because of their versatility in a great range of chemical applications as well as ... -
Computational techniques for virtual reconstruction of fragmented archaeological textiles
(Peer reviewed; Journal article, 2023)Archaeological artifacts play important role in understanding the past developments of the humanity. However, the artifacts are often highly fragmented and degraded, with many details and parts missing due to centuries’ ... -
Multi-analytical investigation into painting materials and techniques: the wall paintings of Abuna Yemata Guh church
(Peer reviewed; Journal article, 2016)Abuna Yemata Guh is one of the nine Saints who are traditionally claimed to have come to Northern Ethiopia in the beginning of the sixth century and established monasteries in the Tigray region. The church, named after ... -
Salt efflorescence in historic wooden buildings
(Peer reviewed; Journal article, 2016)Efflorescence and subflorescence are frequent phenomena occurring in buildings of porous inorganic materials such as bricks, stone, and concrete. Since the above phenomena have detrimental effects, they were the subject ... -
Standardization of Digitized Heritage: A Review of Implementations of 3D in Cultural Heritage
(Peer reviewed; Journal article, 2023)The value of three-dimensional virtual objects are proven in a great variety of applications; their flexibility allowing for a substantial amount of utilization purposes. In cultural heritage this has been used for many ... -
Tensor decomposition for painting analysis. Part 1: pigment characterization
(Journal article; Peer reviewed, 2023)Photo-sensitive materials tend to change with exposure to light. Often, this change is visible when it affects the reflectance of the material in the visible range of the electromagnetic spectrum. In order to understand ... -
Tensor decomposition for painting analysis. Part 2: spatio-temporal simulation
(Journal article; Peer reviewed, 2023)In a previous article, we modelled the spectral and temporal dimensions of the photodegradation behaviour of pigments in the painting “A Japanese Lantern” by Oda Krohg. In particular, we extracted the endmembers and spectral ...
