Denoising ECG by a New Wavelet Threshold Function
2021 14th International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI)（2021）
Abstract
Electrocardiogram (ECG) signal is an important physiological signal which contains cardiac information and is the basis to diagnosis cardiac related diseases. The advantages of wavelet analysis are illustrated by results from denoising the ECG signals for its highly versatility. In this paper, an improved threshold function, erf function, is proposed to overcome the deficiency of the classic soft ...
