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

Figure 1

The graphs of the chosen methods (for evaluation of the ECG signal quality after compression) without diagnostic information. On the x-axis there are values of avL in bps; on the y-axis there are values of each method’s results. The algorithms were tested on all 15 leads of all 125 signals of the CSE database. The blue and the red curves represent signals where the DC component is present or is subtracted, respectively. One curve represents one averaged lead.
