Pick-up the Musical Information from Digital Musical Score Based on Mathematical Morphology and Music Notation

The basic rule of musical notation for image processing is analyzed, in this paper. Using the structuring elements of musical notation and the basic algorithms of mathematical morphology, a new recognizing for the musical information of digital musical score is presented, and then the musical information is transformed to MIDI file for the communication and restoration of musical score. The results of experiment show that the statistic average value of recognition rate for musical information from digital musical score is 94.4%, and can be satisfied the practical applied demand, and it is a new way for applications of digital library, musical education, musical theory analysis and so on.
