BoundingBox class
Identifies the bounding box around the label, face, text or personal
protective equipment. 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.
