自动音乐转录中的音符识别包括两个过程：同时分组和顺序分组。前者从频率分量生成音符，而后者生成音符的时间序列。他们的主要问题分别是音符组成和设计有效的音乐流创建功能的消歧。对于同时分组，为了科普该问题，基于频率分量的重叠检测来创建注意假设。对于顺序分组，音色相似性和方向接近性被集成。在消声室中录制的四重奏音乐的实验结果表明，所提出的方法提高了每一组的F-措施分别为0.10和0.14。
Note recognition in automatic music transcription consists of two processes: simultaneous grouping and sequential grouping. The former generates a note from frequency components, while the latter generates a temporal sequence of notes. Their main problem are disambiguation in note composition and design of features effective for music stream creation, respectively. For the simultaneous grouping, to cope with the problem note hypotheses are created based on overlap detection of frequency components. For the sequential grouping, timbre similarity and direction proximity are integrated. The result of experiments with quartet music recorded in an anechoic chamber showed that the proposed method improved the F-measure of each grouping by 0.10 and 0.14, respectively.
