【摘要】 本文提供了一个基于投影方法的印刷体五线谱识别系统.在系统处理过程中使用了投影方法,并适当使用了语法规则,乐谱句法知识和拆分结构等方法,本系统对噪声、轻度倾斜(八度以内)和弯曲有较好的容错能力.全过程用Borland C++(源程序约四千条)在PC 386微机上完成.文中以一段乐谱为例给出了文本输出数据,并对试验结果进行了分析.更多还原

【Abstract】 A system of automatic recognition of printed music based on projection is introduced. The method of projection has been used efficiently in the system. In some steps, projections on different directions are taken repeatly to handle the very subtle features of the symbols. Local and regional projections are used to identify music symbols in the recognition step. It should be noted that the system is allowable of slight inclination (within 8 degree), curvature, and local variation of thickness on staff lines. Examples and diagrams of music image processing has been shown in the paper. A text output is also given and experiments on three music scores are analysed to evaluate the system.更多还原
