Background A new framework for heart sound analysis is proposed. One of the most difficult
processes in heart sound analysis is segmentation, due to interference form murmurs …

This paper presents a multi-centroid diastolic duration model for the hidden semi-Markov
model (HSMM) based heart sound segmentation. The centroids are calculated by …

A multi-channel wearable heart sound visualization system based on novel heart sound
sensors for imaging cardiac acoustic maps was developed and designed. The cardiac …

Developing countries have a large population of children living with undiagnosed heart
murmurs. As a result of an accompanying skills shortage, most of these children will not get …

This paper describes a system for discriminating innocent from pathologic systolic heart
murmurs in children based on auscultation recordings. For sound signal analysis the use of …

One of the major current limitations in the diagnosis derived from auscultation remains the
ambient noise surrounding the subject, which prevents successful auscultation. Therefore, it …

The purpose of computer-aided diagnosis (CAD) systems is to improve the detection of
diseases in a shorter time and with reduced subjectivity. A robust system frequently requires …

Respiratory infections in children increase the risk of fatal lung disease, making effective
identification and analysis of breath sounds essential. However, most studies have focused …

The research and application of heart sound (HS) analysis for cardiovascular disease (CVD)
diagnosis has attracted more attention recently. Unlike other relevant HS analysis research …

The present paper investigates the ability of a chirplet model to be considered as a pattern
generating a mother wavelet for time–scale analysis of heart sounds. The choice of the …
