Biomedical Signal Reconstruction Using Gabor Spectral Tracking Technique

One of the ECG signal processing aims is to smooth the data to reduce high-frequency artifacts and to retain features within the waves. Conventional techniques may cause reduction on R-wave peaks such that the reduced ratio of R to T wave may cause misdiagnosis. In the study, the Gabor spectral tracking technique is first proposed and implemented to cope with this drawback without missing tiny significant information after noisy interferences are removed. Using the proposed technique to obtain smoothed ECG signals can be an effective tool for clinic or diagnostic purpose.
