Robust Identification of Motor Unit Discharges From High-Density Surface EMG in Dynamic Muscle Contractions of the Tibialis Anterior

数据如何分段

• The recorded signals were divided into 4 s long segments, which can be regarded as semi-isometric contraction, with 50 % overlapping and concatenated the segments from the five trials at a same timing.
• 怎么匹配不同区间上的mu？通过重叠部分。如果匹配程度＞90那么就说明是同一个mu
• 如何获取整个区间上的波形？通过插值来获取这个MUAP的动态变化，获得更高的分辨率
