A Comparative Analysis of Methods for Evaluation of ECG Signal Quality after Compression
Table 5
Recommendations for compression. All the methods suitable for assessment of signal quality after compression are listed. These methods are separated into four groups according to the cluster analysis. Each group is separated by a horizontal line. The recommendations are determined in three ranges (min, max, and median case) according to Table 2. Using this table, the signals after compression can be divided into three groups of quality and the user does not have to know or set avL. The last column of this table informs us about the computational demand of the methods (1: low, 2: medium, 3: high). On the basis of five criteria, we recommend a total of eight methods for signal quality evaluation, which are highlighted in bold. The methods are diversified, which means that they come from all four clusters (which represent four different trends) and are based on various principles. The other methods from the table can be used as well since they are valid, while they are not the best.
