Comparison of onset detection performance using different methods (mean ± standard error).

<p>AMP: the conventional amplitude thresholding method; TKEO: the method based on TKE operation conditioning; Bonato: the double threshold algorithm developed by Bonato et al. [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0127990#pone.0127990.ref006" target="_blank">6</a>]; SGMM: the sequential GMM based unsupervised learning method. For each SNR level, the mean latency was averaged over 60 trials of simulated surface EMG signals.
