Abstract

In this paper, a new watermarking algorithm to realize synchronous transmission of Gong-Che Notation musical score image and its MIDI information was been present. Firstly, it transforms the MIDI information to a sequence of 0 1 codes which is the watermarking data, then it embeds the watermarking data into the Gong-Che Notation musical score image by clockwise inward rotating order, finally, it judges whether the Gong-Che Notation musical score image need expand to avoid loss musical information by computing number of connected component labeling. Experiments shows that the expanded times are no more than Len(M(2))/(2H*W).
