PROJECT TITLE :
Fetal heart beat detection by Hilbert transform and non-linear state-space projections
This study describes an integrated approach for fetal heart beat detection from abdominal ECG signals. The signal is initial processed by the primary-order distinction operation, and then, the envelope of the differentiated signal is given by the Hilbert transform, which indicates both the maternal and fetal heart beats. When that, the non-linear state-area projections is applied to the envelope signal to get rid of the maternal heart beats, obtaining the fetal heart beats envelope. The validity and performance of the described technique are confirmed through experiments on real ECG knowledge. A comparison with the well-known independent part analysis method has also been presented.
