Digits play an essential role in music scores and need to be reconstructed correctly by any Optical Music Recognition system. This challenge is frequently underestimated and can be a potential source of error if done incorrectly. Typical challenges come from the contextual nature of music notation, ambiguities and general computer-vision issues stemming from image acquisition. In this paper, we discuss the nature of this problem, how image-based methods can be used to tackle them and why they are not enough to fully solve this challenge.
