tf.keras.preprocessing.image.random_brightness(
    x,
    brightness_range
)

Defined in tensorflow/python/keras/_impl/keras/preprocessing/image.py.

Performs a random adjustment of brightness of a Numpy image tensor.

Arguments:

  • x: Input tensor. Must be 3D.
  • brightness_range: Tuple of floats; range to pick a brightness value from.

Returns:

Brightness adjusted Numpy image tensor.

Raises:

  • ValueError: if brightness_range isn't a tuple.
