 Computing the onset of an EMG signal can be quite tricky. In this example, we describe a pipeline for a straightforward estimation of EMG onset based on the EMG envelope and [[Visual3D:Documentation:Pipeline:Event_Commands:Event_Threshold|Event Threshold]]. This is not a definitive definition, but simply a starting point for the user. Two events should be created at the start and beginning of the rest period. Three event labels are identified on this figure. The yellow and red events specify the "rest period". This is arbitrary and is specified by the user explicitly. The blue event label is the first threshold crossing above the "median + 3*standard deviation". Computing the onset of an EMG signal can be quite tricky.

 Computing the onset of an EMG signal can be quite tricky. In this example, we describe a pipeline for a straightforward estimation of EMG onset based on the the [[Visual3D:Documentation:Pipeline:Signal_Commands:Teager_Kaiser_Energy|Teager-Kaiser Energy Operator]] and [[Visual3D:Documentation:Pipeline:Event_Commands:Event_Threshold|Event_Threshold]]. This is not a definitive definition, but simply a starting point for the user. The following figure shows an EMG signal before and after the Teager Kaiser Energy Operator is implemented. Computing the onset of an EMG signal can be quite tricky.
