Method Pros and cons
Complex
Continuous
Wavelet
Transform
-Computationally fast and the accuracy of the method is high.
-Algorithm’s parameters increase the system’s efficacy.
Wavelet
Transform
-More Flexible and efficient tool for FHR detection and denoising the noise components than the traditional filtering techniques.
Artificial
Neural
Networks
-Very fast and computer categorization can be done.
-Sometimes it fails to estimate the exact base line value.
-Relatively SNR is high.
Independent
Component
Analysis
-Overall performance is medium.
-Priori information is not required.
-Relatively high SNR.
Kalman Filtering -Real time implementation is possible but complex.
-Efficiency is high.
SVD,PCA -Overall performance is low.
-Relatively SNR is low.
-Real time implementation is possible and simple.
