| 摘 要： | 计算机光学乐谱识别(OpticalMusicRecognition,OMR)利用扫描仪等数码设备,对已有的纸质乐谱进行扫描,形成数字乐谱图像,再利用专用的软件系统进行处理与识别,提取出音乐信息.文章根据乐谱中音乐符号的统计与结构特征,提出了方向数的概念,并构造出方向数探测法,利用此方法对倾斜数字乐谱图像进行谱线、小节线和符干的识别,通过对50例乐谱的试验,取得较好的效果.

| Abstract: | Optical Music Recognition (OMR) is the automatic recognition of a scanned page of printed music notation by computer. A new approach to this pattern recognition problem is presented in this paper. The concept of direction number has been defined according to the musical notation's statistic and structural characteristic, specialized algorithms are recognition staves, making use of our proposed algorithms, which can process oblique musical score. At last, about 50 musical score image which are downloaded from the websites have been used to demonstrate the efficiency and accuracy of the system. |
