“…The fiducial-based methods extract time domain characteristic, amplitude, area, and angle from an ECG signal. An example of feature points that can be extracted are such as the amplitudes of the P, R, and T waves, the temporal distance between wave boundaries (onset and offset of the P, Q, R, S, and T waves), the area of the waves, and the slope information [11]. The non fiducial-based methods do not use the characteristic point as features, instead it dwells on features like wavelet coefficients and power spectral density.…”
