Biometric Identification Method for Heart Sound Based on Multimodal Multiscale Dispersion Entropy
Entropy, 2020 In this paper, a new method of biometric characterization of heart sounds based on multimodal multiscale dispersion entropy is proposed. Firstly, the heart sound is periodically segmented, and then each single-cycle heart sound is decomposed into a group
