tf.image.random_saturation(image, lower, upper, seed=None)

tf.image.random_saturation(image, lower, upper, seed=None)

See the guide: Images > Image Adjustments

Adjust the saturation of an RGB image by a random factor.

Equivalent to adjust_saturation() but uses a saturation_factor randomly picked in the interval [lower, upper].

Args:

• image: RGB image or images. Size of the last dimension must be 3.
• lower: float. Lower bound for the random saturation factor.
• upper: float. Upper bound for the random saturation factor.
• seed: An operation-specific seed. It will be used in conjunction with the graph-level seed to determine the real seeds that will be used in this operation. Please see the documentation of set_random_seed for its interaction with the graph-level random seed.

Returns:

Adjusted image(s), same shape and DType as image.

Raises:

• ValueError: if upper <= lower or if lower < 0.
