【摘要】 该文主要是脉搏波极值点识别的研究,提出一种新的算法即基于二阶导数的极值点来对应原始脉搏波的拐点,阐述算法原理,将其与传统的针对原始波形的极值法进行对比,实践证明,基于二阶导数的极值点识别法更准确且稳定性较好。更多还原

【Abstract】 This paper is mainly talking about the recognition of the pulse wave’s extreme point,and puts forward a new algo rithm based on the extreme point of the second derivative which corresponds to the inflection point of the original pulse wave,It elaborates the algorithm principle and compares the new algorithm and the traditional extreme value method for the original wave.The practice has proved that the new is more accurate and its error is smaller.更多还原
