本文利用多重分形去趋势波动分析(MFDFA)对人体步态时间序列进行了研究。据观察,长程相关是主要负责的多重分形的起源。研究表明,正常集的多重分形程度大于患病集。然而,该方法无法区分两个患病组。
In this paper multifractal detrended fluctuation analysis (MFDFA) is used to study the human gait time series for normal and diseased sets. It is observed that long range correlation is primarily responsible for the origin of multifractality. The study reveals that the degree of multifractality is more for normal set compared to diseased set. However, the method fails to distinguish between the two diseased sets.
