Box and whisker plot of the AUC of PR curves of the original signal and the 8 techniques for several SNRs are displayed. Generally, all methods show better results when the SNR increases except the ZSOI. All methods exhibit poor performances for SNRs below 5dB without having one method being significantly better than another one. In most cases, the ERSP, the Zbaseline and ZH0 methods exhibit the best results. It is noteworthy that ZH0 is the only method which does not require to define a baseline.
