description: Adjust the brightness of images by a random factor.

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.
