METHOD FOR REMOVING THE STAFF LINES FROM A MUSIC SCORE IMAGE

摘要

A method for removing staff lines from a music score image is provided to recognize a music score accurately by removing staff lines from a music score image photographed in a cellular phone without compensating the additional inclination of the staff lines that requires many calculations. It is detected that a region where staff lines exit from an image including a music score(100,200), and the staff lines which are extended continuously in their lengths are split into several regions by considering the inclination of the staff lines(300). The each line of the staff line included at the music score is estimated at the split regions by analyzing a histogram(400). Based on the estimated staff line, the each line of the staff line included the music score is extracted(500). The extracted each line of the staff line is removed from the music score(600). When detecting the region where the staff line exist, the histogram is calculated and the distribution of the histogram is checked.
