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

Table 3

Differences of methods tested on signals without and with subtraction of the DC component. The methods that are not sensitive to subtraction of the DC component are highlighted in italic, and slightly sensitive methods are highlighted in bold, while highly sensitive methods are highlighted in underline. The difference values are average differences for all samples of all curves for the given method. Differences are normalized on the range <0, 1> according to the range of their values on the not equally sampled interval of avL <0.1, 9>; the average may differ on different avL interval.
