摘要:
 脉搏波特征反映着人体生理病理状态,本文基于高斯混合模型提出一种脉搏波特征提取方法。该方法利用脉搏波的一、二阶差分信号的零点确定脉搏波特征点的数目及类型,并采用泰勒级数展开简化特征点位置估计的复杂度。仿真及实际数据的处理结果表明,本文所提出的方法相对经典算法能更精确地实现脉搏波特征点的定位及信息获取,是一种有效的脉搏波特征提取方法。
Abstract:
 Abstract: The features of pulse wave reflect the physiological and pathological states of human body. A method based on Gaussian mixture model was proposed for the feature extraction of pulse wave. In this method, the number and type of pulse wave feature points were determined by the zero point of the first difference signal and the second difference signal of pulse wave, and the complexity of the location estimation of the feature point was simplified by Taylor series expansion. The simulated and actual data processing results showed that the proposed method acquired the location and information of pulse wave feature points more accurately as comparison with classic algorithms. The proposed method is an effective method for the feature extraction of pulse wave.
