summary: "Draw bounding boxes on a batch of images."
description: <<END
Outputs a copy of `images` but draws on top of the pixels zero or more bounding
boxes specified by the locations in `boxes`. The coordinates of the each
bounding box in `boxes` are encoded as `[y_min, x_min, y_max, x_max]`. The
bounding box coordinates are floats in `[0.0, 1.0]` relative to the width and
height of the underlying image.
For example, if an image is 100 x 200 pixels (height x width) and the bounding
box is `[0.1, 0.2, 0.5, 0.9]`, the upper-left and bottom-right coordinates of
the bounding box will be `(40, 10)` to `(180, 50)` (in (x,y) coordinates).
Parts of the bounding box may fall outside the image.
