Detailed Description

This is the multi-target tracker.

Parameters
----------
metric : nn_matching.NearestNeighborDistanceMetric
    A distance metric for measurement-to-track association.
max_age : int
    Maximum number of missed misses before a track is deleted.
n_init : int
    Number of consecutive detections before the track is confirmed. The
    track state is set to `Deleted` if a miss occurs within the first
    `n_init` frames.

Attributes
----------
metric : nn_matching.NearestNeighborDistanceMetric
    The distance metric used for measurement to track association.
max_age : int
    Maximum number of missed misses before a track is deleted.
n_init : int
    Number of frames that a track remains in initialization phase.
kf : kalman_filter.KalmanFilter
    A Kalman filter to filter target trajectories in image space.
tracks : List[Track]
    The list of active tracks at the current time step.

def deep_sort.tracker.Tracker.predict ( self )

Propagate track state distributions one time step forward.

This function should be called once every time step, before `update`.

def deep_sort.tracker.Tracker.update	(	self,
		detections
	)

Perform measurement update and track management.

Parameters
----------
detections : List[deep_sort.detection.Detection]
    A list of detections at the current time step.
