- Abstract:
- Abstract: The noise of heart sound signals was removed and the envelope curve of the heart sound segment was extracted based on the features of the heart sound signal in the time domain. Subsequently, the feature point screening of the heart sound signal is performed on the envelope curve, and the start and end points of the S1 and S2 signal segments are filtered. The heart sound signal is segmented and the relevant parameters are calculated for the classification of different heart sound signals. Finally, the experimental results are summarized for providing a diagnostic basis for the study on heart sound signals.
