    # have an estimated range of 4-8.

    # Identifies the bounding box around the object or face. The `left`
    # (x-coordinate) and `top` (y-coordinate) are coordinates representing
    # the top and left sides of the bounding box. Note that the upper-left
    # corner of the image is the origin (0,0).
    #
    # The `top` and `left` values returned are ratios of the overall image
    # size. For example, if the input image is 700x200 pixels, and the
    # top-left coordinate of the bounding box is 350x50 pixels, the API
    # returns a `left` value of 0.5 (350/700) and a `top` value of 0.25
    # (50/200).
    #
    # The `width` and `height` values represent the dimensions of the
    # bounding box as a ratio of the overall image dimension. For example,
    # if the input image is 700x200 pixels, and the bounding box width is 70
    # pixels, the width returned is 0.1.
    #
    # <note markdown="1"> The bounding box coordinates can have negative values. For example, if
    # Amazon Rekognition is able to detect a face that is at the image edge
    # and is only partially visible, the service can return coordinates that
    # are outside the image bounds and, depending on the image edge, you
    # might get negative values or values greater than 1 for the `left` or
    # `top` values.
