`tf.compat.v1.keras.preprocessing.image.random_brightness`
tf.keras.preprocessing.image.random_brightness(
x, brightness_range, scale=True
)
Args |
|---|
x
|
Input tensor. Must be 3D.
|
brightness_range
|
Tuple of floats; brightness range.
|
scale
|
Whether to rescale the image such that minimum and maximum values
are 0 and 255 respectively. Default: True.
|
Returns |
|---|
|
Numpy image tensor.
|
Raises |
|---|
ValueError if brightness_range isn't a tuple.
