Ink discrimination based on co-occurrence analysis of visible and infrared images

By Vassiliki Kokla, Alexandra Psarrou and Vassilis Konstantinou


Inks found in Byzantine manuscripts are semitransparent\ud pigments and their examination and analysis\ud provide an invaluable source of information on the authenticity\ud and dating of manuscripts and the number of\ud authors involved. However, inks are difficult to characterize\ud because their intensity depends on the amount of liquid\ud spread during scripting and the reflective properties of\ud the support. Most existing methods for the analysis of\ud ink materials are based on destructive testing techniques\ud that require the physicochemical sampling of data. Such\ud methods cannot be widely used because of the historical\ud and cultural value of the manuscripts. In this work we\ud show that manuscript inks can be represented through a\ud mixture of Gaussian functions and can be characterised\ud using co-occurrence matrices
