ZeniProcedure

class pyCGM2.Events.eventProcedures.ZeniProcedure

Gait event detection procedure based on the method described by Zeni et al., 2008.

This procedure implements a gait event detection algorithm that identifies foot strike and foot off events based on the motion of heel and toe markers relative to the pelvis.

description

Description of the event detection procedure.

Type:

str

footStrikeOffset

Systematic offset applied to each foot strike event.

Type:

int

footOffOffset

Systematic offset applied to each foot off event.

Type:

int

__init__()

Initializes the ZeniProcedure class.

Methods

__init__()	Initializes the ZeniProcedure class.
detect(acq)	Detect events using the Zeni method.
setFootOffOffset(value)	Set a systematic offset to each foot off event.
setFootStrikeOffset(value)	Set a systematic offset to each foot strike event.

detect(acq: btkAcquisition) → Tuple[int, int, int, int] | int

Detect events using the Zeni method.

Parameters:

acq (btk.btkAcquisition) – A BTK acquisition instance containing motion capture data.

Returns:

Union[Tuple[int, int, int, int], int] – Frames indicating the left foot strike, left foot off, right foot strike, and right foot off respectively. Returns 0 if detection fails.

setFootOffOffset(value: int)

Set a systematic offset to each foot off event.

Parameters:

value (int) – Frame offset to apply to each foot off event.

setFootStrikeOffset(value: int)

Set a systematic offset to each foot strike event.

Parameters:

value (int) – Frame offset to apply to each foot strike event.
