摘要
•We propose a novel method for recognition of pulse wave feature points based on angle mapping, which can amplify the changes in pulse waveform and provide better noise immunity.•The accuracy of this method is discussed by using approximate pulse wave and mathematical model.•This method is an efficient choice for the identification of unobvious feature points.•This method can provide threshold standard for existence of unobvious feature points.
