ABSTRACT

A system of automatic recognition of printed music based on projection is introduced. The method of projection has been used efficiently in the system. In some steps, projections on different directions are taken repeatedly to handle the very subtle features of the symbols. Local and regional projections are used to identify music symbols in the recognition step. It should be noted that the system is allowable of slight inclination (within 8 degrees), curvature and location variation of thickness on staff lines. Examples and diagrams of music image processing has been shown in the paper. A text output is also given and experiments on three music scores are analyzed to evaluate the system.

Key words:Music staff, Music recognition, Projection.
