Visual Perception of Music Notation: On-Line and Off-Line Recognition (Repost)

One of the initial challenges in any Optical Music Recognition (OMR) system is the treatment of the staves. For musicians, stavelines are required to facilitate reading the notes. For the machine, however, it becomes an obstacle for making the segmentation of the symbols very difficult. The task of separating
background from foreground figures is an unsolved problem in many machine pattern recognition systems in general.
