Figure 1From: An automated tool for localization of heart sound components S1, S2, S3 and S4 in pulmonary sounds using Hilbert transform and Heron’s formula Flow chart of the proposed method. Sub-figures (a)-(f) depict the outcomes of the different steps of the proposed method. The sound signal displayed in (a) corresponds to high flow mixed signal. The white arrowheads in (d) indicate the the events that correspond to HS and LS components.Back to article page
