Draw bounding boxes on a batch of images.
tf.image.draw_bounding_boxes(
images, boxes, name=None, colors=None
)
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.
