    ECG signal performance de-noising assessment based on threshold tuning of dual-tree wavelet transform

    Since the electrocardiogram (ECG) signal has a low frequency and a weak amplitude, it is sensitive to miscellaneous mixed noises, which may reduce the diagnostic accuracy and hinder the physician’s correct dec...

    Exploiting temporal and nonstationary features in breathing sound analysis for multiple obstructive sleep apnea severity classification

    Polysomnography (PSG) is the gold standard test for obstructive sleep apnea (OSA), but it incurs high costs, requires inconvenient measurements, and is limited by a one-night test. Thus, a repetitive OSA scree...
