ABSTRACT
An electrocardiogram (ECG) system deals with several challenges related with noise sources. The denoising process is a challenge due to ECG signal amplitude with respect to noise amplitude. The filtering process can be executed by analogue filters or digital filters, however, modern systems uses digital filters mainly because their flexibility, efficiency and hardware costs reduction. This paper compares the ability of two digital techniques used in ECG denoising, namely Adaptive Filter (AF) and Singular Value Decomposition (SVD). The techniques were applied to real ECG signals contaminated with the most common noise sources; artefacts caused by electromyography (EMG) and power line noise (Hum).

Single-channel fetal ECG extraction method based on extended Kalman filtering with singular value decomposition algorithm
AbstractIn this paper, an approach based on extended Kalman filtering (EKF) combined with singular value decomposition (SVD) was proposed to extract fetal electrocardiogram (fECG) from single-channel abdominal ECG recording. First, on the basis of dynamic ...
Impulse noise reduction in medical images with the use of switch mode fuzzy adaptive median filter
In this paper, a novel fuzzy adaptive median filter is presented for the noise reduction in MR images corrupted with heavy impulse (salt&pepper) noise. We propose a switch mode fuzzy adaptive median filter (SMFAMF) for removing highly corrupted salt&...

MUSP'08: Proceedings of the 8th WSEAS International Conference on Multimedia systems and signal processingThe electrocardiogram has considerable diagnostic significance, and application of ECG monitoring are diverse and in wide use. For diagnostic- quality ECG recordings, signal acquisition must be noise free. The signal acquisition is susceptible to the ...
