tf.image.random_saturation
Adjust the saturation of RGB images by a random factor.
tf.image.random_saturation(
image, lower, upper, seed=None
)
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. |
