The wavelet transform has emerged over recent years as a powerful time–frequency
analysis and signal coding tool favoured for the interrogation of complex nonstationary …

The automatic and accurate P phase arrival identification is a fundamental problem for
seismologists worldwide. Several approaches have been reported in the literature, but most …

Auscultation of the lung sound is a simple and noninvasive method to obtain some instant
but useful informations to detect various respiratory diseases. However, one of the main …

Abnormal breath sounds like wheezes are observed in patients with obstructive pulmonary
diseases. The aim of this study was to construct an automatic technique for wheeze …

Respiratory sounds are always contaminated by heart sound interference. An essential
preprocessing step in some of the heart sound cancellation methods is localizing primary …

Pneumonia is the cause of death for over a million children each year around the world,
largely in resource poor regions such as sub-Saharan Africa and remote Asia. One of the …

Abstract Computerized analysis of Lung Sound (LS) is a promising method for assessing
pulmonary function. However, the LS signal is severely contaminated by background noise …

Abstract Background: The World Health Organization (WHO) establishes as a top priority the
early detection of respiratory diseases. This detection could be performed by means of …

An efficient technique for detecting explosive lung sounds (LS)(fine/coarse crackles and
squawks) or bowel sounds (BS) in clinical auscultative recordings is presented. The …

In this work, we propose a novel denoising method based on evaluation of higher-order
statistics at different Wavelet bands for an electrocardiogram (ECG) signal. Higher-order …
