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.
Args | |
---|---|
images | A Tensor . Must be one of the following types: float32 , half . 4-D with shape [batch, height, width, depth] . A batch of images. |
boxes | A Tensor of type float32 . 3-D with shape [batch, num_bounding_boxes, 4] containing bounding boxes. |
name | A name for the operation (optional). |
Returns | |
---|---|
A Tensor . Has the same type as images . |
