There's a project that does exactly this at Nijmegen based Radboud
University (The Netherlands). Info (didn't check if there's an English translation) and links at http://www.ru.nl/wetenschapsagenda/editie_19_-_17_juni/vm/jaargang_3/beeld_o...
Thank you!
I don't see any transcriptions here, however. Or was the original manuscript in Dutch?
