“…This procedure is the most frequently used (Merletti et al, 2003;Beretta Piccoli et al, 2014;GuzmanVenegas et al, 2014), although some more objective and automated methods have been proposed (Cescon, 2006;Ullah et al, 2014). The visual method has been considered as the gold standard to give validity to other procedures (Ullah et al, 2014). Nevertheless, this method has some drawbacks.…”

“…The matched filter method proposed by Mesin et al [19] had an average error of 0.3 IED (ratio) reaching values higher than 1 IED for the simulated sEMG signals with up to two IZs in each frame and SNR value of 20 dB [20]. This method is in fact the first step (i.e., template matching) of the sEMG decomposition method proposed by Gazzoni et al [62].…”

“…This method is in fact the first step (i.e., template matching) of the sEMG decomposition method proposed by Gazzoni et al [62]. Since the approach proposed by Gazzoni et al relied on MUAP segmentation in each recording channel, it failed in not only very high-SNR data to some extent [20], but in low-SNR data more frequently. Image processing methods are preferred because no detection threshold is required for the MUAPs and the whole image frame is analyzed, compared with each signal.…”
