Identifies the bounding box around the label, face, text, object of interest, 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.
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.
