独立分量分析在表面肌电信号分解中的应用
The Application of Independent Component Analysis for Decomposition Surface EMG
【摘要】 采用独立分量分析中的信息极大化快速算法初步探讨了表面肌电信号的分解问题。研究结果表明 ,独立分量分析对肌肉轻度收缩力水平下 (<10 %MVC)表面肌电信号的分解有较好的效果 ,可以作为表面肌电信号分解的一种预处理手段
【Abstract】 The surface EMG(SEMG) signals decomposition algorithm based on independent component analysis(ICA) were exploned. A preliminary experiment was studied. The results show that this method can decompose the SEMG signal efficiently when the muscle contract level up to 10% of maximal voluntary contraction (MVC). It can be concluded that ICA is a promising method of preprocessing for SEMG decomposition.
