    A class for defining a polygon-shaped zone within a frame for detecting objects.

    Attributes:
        polygon (np.ndarray): A polygon represented by a numpy array of shape
            `(N, 2)`, containing the `x`, `y` coordinates of the points.
        frame_resolution_wh (Tuple[int, int]): The frame resolution (width, height)
        triggering_position (Position): The position within the bounding
            box that triggers the zone (default: Position.BOTTOM_CENTER)
        current_count (int): The current count of detected objects within the zone
        mask (np.ndarray): The 2D bool mask for the polygon zone

        Determines if the detections are within the polygon zone.

        Parameters:
            detections (Detections): The detections
                to be checked against the polygon zone

        Returns:
            np.ndarray: A boolean numpy array indicating
                if each detection is within the polygon zone

    A class for annotating a polygon-shaped zone within a
        frame with a count of detected objects.

    Attributes:
        zone (PolygonZone): The polygon zone to be annotated
        color (Color): The color to draw the polygon lines
        thickness (int): The thickness of the polygon lines, default is 2
        text_color (Color): The color of the text on the polygon, default is black
        text_scale (float): The scale of the text on the polygon, default is 0.5
        text_thickness (int): The thickness of the text on the polygon, default is 1
        text_padding (int): The padding around the text on the polygon, default is 10
        font (int): The font type for the text on the polygon,
            default is cv2.FONT_HERSHEY_SIMPLEX
        center (Tuple[int, int]): The center of the polygon for text placement
