ThresholdAnnotation

Bases: SignalAnnotation

Annotate the locations in a signal where a threshold value is crossed. Only crossings exceeding the threshold value are considered. This means a signal going from a lower value to a higher value than the threshold.

Attributes:

Name	Type	Description
signals	ndarray	an array of the signals to find peaks in
threshold	number	a threshold value that must be crossed

fs = int(1000 / signals.fs) instance-attribute

threshold = signals.threshold instance-attribute

__init__(signals)

annotate()

Annotate the indices in a signal where a threshold value is crossed.

The returning array will be of shape (len(signals), max_number_of_crossings)

Returns:

Type	Description
ndarray	np.ndarray: an array of the crossing indices
