vista.algorithms.trackers.kalman_tracker.run_kalman_tracker(detectors, config)

Run Kalman filter tracker on detections using a custom implementation.

Parameters:

• detectors (list of Detector) – List of Detector objects to use as input

• config (dict) –

  Dictionary containing tracker configuration:

  • tracker_name: Name for the resulting tracker

  • process_noise: Process noise for constant velocity model

  • measurement_noise: Measurement noise covariance

  • gating_distance: Mahalanobis distance threshold for gating

  • min_detections: Minimum detections required to initiate track

  • delete_threshold: Covariance trace threshold for track deletion

Returns:

List of track data dictionaries, each containing:

• ’frames’: numpy array of frame numbers

• ’rows’: numpy array of row coordinates

• ’columns’: numpy array of column coordinates

Return type:

list of dict
