Double tree decomposition of lung sounds

The analysis of respiratory sounds highlights the limits of commonly used techniques as a huge variety of sounds can be observed (stationary or nonstationary and of different durations) which can have themselves a great variability. New approaches have been developed in order to associate the acoust...

More Information
Summary:The analysis of respiratory sounds highlights the limits of commonly used techniques as a huge variety of sounds can be observed (stationary or nonstationary and of different durations) which can have themselves a great variability. New approaches have been developed in order to associate the acoustic phenomena to the respiratory flow and volume. We present here another approach only based on the wavelet packet decomposition to segment respiratory sounds.
