| 摘 要： | 表面肌电信号(surface EMG,sEMG)是一种复杂的非线性信号.近年来,分形分析常被用来揭示这种非线性特征.本文采用一种基于模糊自相似性的分数维计算方法,来获取前臂执行四种动作时所对应的动作sEMG的分数维.结果表明,通过这种方法获得的分数维能够聚集在各自特定的范围内,并且,通过分形维能够区分部分动作sEMG.

| Abstract: | Surface EMG is a complex nonlinear signal.In recent years,fractal analysis has been often used to disclose the nonlinear characteristics underlying the sEMG.A method based on the fuzzy self-similarity was employed to calculate the fractal dimension of four kinds of action sEMG.The results showed that the fractal dimensions calculated by the method could focus on their own special ranges,and some kinds of sEMG could be identified by the way of their fractal dimensions. |
