乐谱识别中音符分割技术的研究

Researches on music segmentation technology of OMR

对乐谱识别中的音符图像分割技术进行了研究,采用游程分析与二次投影技术对乐谱图像进行处理。文中结合乐谱的语法特征对乐谱图像进行分析,先对图像中的音乐音符进行初步分类,对每一类的音符采用不同的处理方法,从而解决了乐符分割的难题。

In this paper an image segment technique of OMR system is proposed. The proposed method is based on analysis of the width of every pixel block and re-projecting the image to segment the music image. To analyze the music notation, music grammar characteristics are combined. Then the music notations are classified roughly. Finally the proposed method take different approaches to different classes of music notation. Experimental results show that the proposed method shed some lights on the difficult OMR problem.
