This paper proposes extraction composed of the following four processes to accurately extract the position of a stave, including inclination, break, and flexion: (1) Find stave candidate points on a scanning line when an image is scanned vertically at equally spaced intervals. (2) Use DP matching to link stave candidate points. (3) Use labeling to separate them into a group for each stave. (4) Extract end points of a stave and correct their positions. When this extraction was applied to 104 printed music scores, it accurately extracted 99.52% of stave positions.
