tf.image.random_brightness
Adjust the brightness of images by a random factor.
tf.image.random_brightness(
image, max_delta, seed=None
)
Equivalent to adjust_brightness() using a delta randomly picked in the interval [-max_delta, max_delta).
| Args | |
|---|---|
image |
An image or images to adjust. |
max_delta |
float, must be non-negative. |
seed |
A Python integer. Used to create a random seed. See tf.compat.v1.set_random_seed for behavior. |
Usage Example:
x = [[[1.0, 2.0, 3.0],
[4.0, 5.0, 6.0]],
[[7.0, 8.0, 9.0],
[10.0, 11.0, 12.0]]]
tf.image.random_brightness(x, 0.2)
<tf.Tensor: shape=(2, 2, 3), dtype=float32, numpy=...>
| Returns | |
|---|---|
| The brightness-adjusted image(s). |
| Raises | |
|---|---|
ValueError |
if max_delta is negative. |
