Recognition musical symbols are very important in music score system and they depend on these methods of researchers. Most of existing approaches for OMR (optical music recognition) removes staff lines before symbols are detected, therefore the symbols can get damaged easily. Another method recognizes symbols without staff line removal but all of them have a low accuracy rate and high processing time for recognizing symbols. In this paper, none staff removal and staff removal are suggested and these new methods are proposed to improve appreciation result of symbols. A lot of symbols are detected before deleted staff line as vertical lines, note head, pitch, beam, tail and then these staff lines are removed to identify other symbols using connected component. The proposed method is applied to the Samsung smart phone which embeds a high resolution camera. Experimental results show that the recognition rate is higher than existing methods and the computation time is reduced significantly.
