Adjust the hue of RGB images by a random factor deterministically.
tf.image.stateless_random_hue(
image, max_delta, seed
)
Equivalent to adjust_hue()
but uses a delta
randomly picked in the
interval [-max_delta, max_delta)
.
Guarantees the same results given the same seed
independent of how many
times the function is called, and independent of global seed settings (e.g.
tf.random.set_seed
).
max_delta
must be in the interval [0, 0.5]
.
Usage Example:
x = [[[1.0, 2.0, 3.0],
[4.0, 5.0, 6.0]],
[[7.0, 8.0, 9.0],
[10.0, 11.0, 12.0]]]
seed = (1, 2)
tf.image.stateless_random_hue(x, 0.2, seed)
<tf.Tensor: shape=(2, 2, 3), dtype=float32, numpy=
array([[[ 1.6514902, 1. , 3. ],
[ 4.65149 , 4. , 6. ]],
[[ 7.65149 , 7. , 9. ],
[10.65149 , 10. , 12. ]]], dtype=float32)>
Args | |
---|---|
image
|
RGB image or images. The size of the last dimension must be 3. |
max_delta
|
float. The maximum value for the random delta. |
seed
|
A shape [2] Tensor, the seed to the random number generator. Must have
dtype int32 or int64 . (When using XLA, only int32 is allowed.)
|
Returns | |
---|---|
Adjusted image(s), same shape and DType as image .
|
Raises | |
---|---|
ValueError
|
if max_delta is invalid.
