UCL Multispectral Processed Images of Parchment Damage Dataset

The data presented here is a set of 2,800 multispectral images of an actual parchment, taken before and after a set of degradation procedures that were designed to match the most likely types of damage which may occur over the lifetime of parchment documents. It is presented here as a source for the digitisation and digital imaging community to allow others to use the dataset for their own research. The image files include various images including raw, white corrected, set registered, and calibration images, and the data set is 72GB in total. The data is available from https://utilities.rd.ucl.ac.uk/published/multispectral.7z The capture, preparation, and structure of this data is described in Giacometti, A., Campagnolo, A., MacDonald, L., Mahony,S., Robson, S., Weyrich, T., Terras, M., Gibson, A.

This article is available in open access and those wishing to use the dataset should make themselves familiar with how the data was created and is organised, which is covered in the article, and also in the Notes section, below
