I applied the techniques You are not allowed to view links. Register or Login to view.. This is research specifically designed to try to identify corrections and overlapping writing in manuscripts.
The dense mark has a distinguishable spectral response, but it isn't clear if it is a different ink or simply different deposition or more pressure was applied when writing. A simple non-linear deposition model (i.e. applying different pressure) could explain most of the spectral differences.
The 'i' in vix mentioned earlier in the thread, as well as the 'x' in poxleber also lights up using the same spectral shape reference map.
The thin 'p' marks are also supported by individual image bands, particularly the UV-filtered images. I found two papers on restoring faded manuscript text, i'm evaluating them to see if they can recover anything in more detail.
