通过每行的小节线特征提取出简谱部分, 然后通过投影法和种子填充算法定位出简谱符号基元的位置, 并由此采用不同的识别算法识别出每个简谱符号基元的类型, 最后通过组装把各个简谱符号组装成音乐特征符, 形成数字化乐谱。-Through each line of the section line feature extraction part of the numbered musical notation, and then through the projection method and seed fill algorithm positioning a numbered musical notation symbols primitive position, and thus adopt different recognition algorithms to identify the numbered musical notation symbols for each element type, and finally through assembly of the various musical notation symbols assembled into the characteristics of Fu, the formation of digital music.
