A Comparative Analysis of Methods for Evaluation of ECG Signal Quality after Compression

Figure 3

The average curves of methods with diagnostic information based on WT. Two types of WT were tested: (a) discrete time dyadic wavelet transform with decimation; (b) stationary wavelet transform. In the case of SWT, methods MSEWPRD RMWSE (purple line) and MSEWPRD RWSE (green dashed line) have the same trend.
