Robust Fetal Heart Beat Detection by Applying Stationary Wavelet Transform
نویسندگان
چکیده
Fetal electrocardiogram (fECG) analysis, i.e., the analysis of the heart rate (HR) and the fECG morphology, offers clinicians vital information about fetal health condition. The fECG can be acquired non-invasively by applying electrodes on maternal abdomen, but the recorded abdominal signal (ADS) contains not only the signal of interest, fECG, but also some physiological (e.g., maternal electrocardiogram) and non-physiological (e.g., power line interference (PLI)) signals, that prevent the direct fECG analysis. An algorithm is proposed for fetal HR extraction, based on stationary wavelet transform (SWT) and independent component analysis (ICA). It is evaluated on real ADS showing good results even for high noise levels.

Audio Analysis using the Discrete Wavelet Transform
The Discrete Wavelet Transform (DWT) is a transformation that can be used to analyze the temporal and spectral properties of non-stationary signals like audio. In this paper we describe some applications of the DWT to the problem of extracting information from non-speech audio. More specifically automatic classification of various types of audio using the DWT is described and compared with othe...

This manuscript addresses the problem of non-invasive fetal Electrocardiogram (ECG) signal acquisition with low power/low complexity sensors. A sensor architecture using the Compressive Sensing (CS) paradigm is compared to a standard compression scheme using wavelets in terms of energy consumption vs. reconstruction quality, and, more importantly, vs. performance of fetal heart beat detection i...
