The Nationaal Archief (National Archives of the Netherlands, The Hague) is conducting an applicability study on the use of QHSI for detecting, measuring and visualizing optical changes in historical documents caused by aging process and conservation treatments. Repeated hyperspectral measurements of a document, taken for example before and after an exhibition, can be used to detect, map and classify subtle changes of the document condition with very high spatial resolution. Due to small differences in the position and deformation of the document during a storage or exhibition period, the measurement data first need to be spatially aligned. Mathematical transformations have to be applied to the hyperspectral image data in order to ensure that any particular pixel coordina...
