2023 13th Workshop on Hyperspectral Imaging and Signal Processing: Evolution in Remote Sensing (WHISPERS) 10.1109/WHISPERS61460.2023.10430960Sammendrag
The map collection, Kartsenteret, of the National Library of Norway is conducting a pilot study of its collection of approximately 150,000 maps. This collection covers a 500-year map and color history. Aiming to study the colors of the historical maps and their relationship, hyperspectral imaging is chosen as the first step where rapid screening and testing of the potential pigments or colorants can be carried out. The estimation is performed by means of spectral distance or similarity measures, tested against an available public dataset of pigments which also contains historical pigments. Finally, we are able to provide a list of pigments as estimated by a spectral distance function, to be validated in further analytical tests.
