tf.image.random_saturation
random_saturation( image, lower, upper, seed=None )
Defined in tensorflow/python/ops/image_ops_impl.py
.
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
: ifupper <= lower
or iflower < 0
