Adaptive Non-Linear Bayesian Filter for ECG Denoising
Journal Title: The International Journal of Technological Exploration and Learning - Year 2014, Vol 3, Issue 3
Abstract
The cycles of an electrocardiogram (ECG) signal contain three components P-wave, QRS complex and the T-wave. Noise is present in cardiograph as signals being measured in which biological resources (muscle contraction, base line drift, motion noise) and environmental resources (power line interference, electrode contact noise, instrumentation noise) are normally pollute ECG signal detected at the electrode. Visu-Shrink thresholding and Bayesian thresholding are the two filters based technique on wavelet method which is denoising the PLI noisy ECG signal. So thresholding techniques are applied for the effectiveness of ECG interval and compared the results with the wavelet soft and hard thresholding methods. The outputs are evaluated by calculating the root mean square (RMS), signal to noise ratio (SNR), correlation coefficient (CC) and power spectral density (PSD) using MATLAB software. The clean ECG signal shows Bayesian thresholding technique is more powerful algorithm for denoising.
