摘要：
Biopotential signal is an electric quantity (voltage or current or field strength), caused by chemical reactions of charged ions. In experimental data collection, a signal of data points does not represent a perfect theoretical expectation. It always contains some noise due to various consequences. Denoising of the ECG wave and MRI image based upon the discrete wavelet transform (DWT) and discrete stationary wavelet transform (SWT) with different threshold techniques has been applied and presented in this paper.
