数字图像净化在乐谱识别中的应用研究

Research and application of the purgation on musical note

本文针对电子音乐制作中扫描结果不理想而影响识别效果的问题,提出了对乐谱的初始扫描结果进行预处理的构思,借助专业知识分析了预处理.的工作原理,给出了具体的实现过程。实验结果表明,对乐谱的扫描结果进行必要的预处理能提高乐谱识别的准确率,并取得满意的演奏效果,从技术上对常用音乐制作软件的功能起到很好的补充、辅助作用。

Regarding to the problem that the unsatisfied scanning results during the musical creation influence identifying those results, putting forward to the preparing to conceive outline, which gives the scanning results a pre-handling, analyzing the principle of the pre-handling process with the help of professional knowledge, giving the detailed carrying out processes. The results of the testing shows that, providing the necessarily pre-handling process to the scanning results of music notes , which can improve the accuracy of identifying the music notes , obtain a satisfied performance result, and give a good complementary and assistant function to the common use musical creation software from the technical respect.
