Our goal is to use computer vision to find commonalities in how faces are painted in late medieval illustrated manuscripts on the example of the Wenceslas Bible. Specifically, for the master illustrator referred to as Frana we want to find out how many illustrators from his workshop contributed to the Bible. We will limit ourselves to depictions of Wenceslas and use face recognition methods to attempt to find stylistic differences which can identify individual illustrators. Further, there are a number of images that might be depictions of Wenceslas, but the actual association is tenuous. We will attempt to use the same face recognition methods to try and answer the question whether or not the images in dispute are actually of Wenceslas.
