Table 2 The integrated profile method utilized for muscle activation onset detection [29]
From: A muscle synergies-based movements detection approach for recognition of the wrist movements
Steps | Description |
|---|---|
\( 1-\mathrm{IP}\left(\mathrm{t}\right)={\sum}_{i=1}^t\mid x(i)\mid \) | Obtaining the integrated profile (x is the EMG signal) |
\( 2-L(t)=\mathrm{IP}(M)\frac{t}{N} \) | Defining a reference line L(t) represents the integral of a signal |
3 − D(t) = ∣ IP(t) − L(t)| | Computing the absolute value of the difference between L(t) and IP(t). (the time point at which D(t) reaches its maximum value, is defined as muscle activation onset time) |
