Read [here](https://supervision.roboflow.com/trackers/) to learn how to plug tracking into your inference pipeline. Attributes: in_count (int): The number of objects that have crossed the line from outside to inside. out_count (int): The number of objects that have crossed the line from inside to outside. startendcCs$t||d|_i|_d|_d|_dS)z Args: start (Point): The starting point of the line. end (Point): The ending point of the line. )r r rN)r vector tracker_statein_count out_count)selfr r rQ/var/www/myenv/lib/python3.10/site-packages/supervision/detection/line_counter.py__init__s zLineZone.__init__ detectionsreturncstt|d}tt|d}t|D]r\}\}}}}} | dur"q|\} } } } t| | dt| | dt| | dt| | dg}fdd|D}tt|dkrPq|d}| jvr_|j| <qj| |krhq|j| <|r{jd7_d ||<qj d7_ d ||<q||fS) a Update the `in_count` and `out_count` based on the objects that cross the line. Args: detections (Detections): A list of detections for which to update the counts. Returns: A tuple of two boolean NumPy arrays. The first array indicates which detections have crossed the line from outside to inside. The second array indicates which detections have crossed the line from inside to outside.
