提出了一种数字乐谱图像识别与匹配方法，采用光学乐谱识别(OMR)技术识别数字乐谱图像建立对应的MIDI 文件，利用一一对

应算法进行匹配，根据相似度来判断同一音乐作品的不同数字版本的乐谱图像，并在理论上就此算法的有效性进行了论证。同时，仿真实

验结果表明这一方法能有效地实现对不同数字版本的同一音乐作品的乐谱图像的识别、归类与校正。-A digital music identification and matching images, the use of optical music recognition (OMR) technology to identify digital music images corresponding MIDI file, using one-to-one matching algorithm, in accordance with the same similarity to determine the number of musical versions of the different scores of images, and in theory, the effectiveness of this algorithm were demonstrated. At the same time, simulation results show that this method can effectively achieve the number of different versions of the same musical scores of images to identify, classify and correction.
