# tf.image.stateless_random_contrast

Adjust the contrast of images by a random factor deterministically.

### Used in the notebooks

Used in the tutorials

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`).

`image` An image tensor with 3 or more dimensions.
`lower` float. Lower bound for the random contrast factor.
`upper` float. Upper bound for the random contrast factor.
`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.)

#### 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_contrast(x, 0.2, 0.5, seed)`
`<tf.Tensor: shape=(2, 2, 3), dtype=float32, numpy=`
`array([[[3.4605184, 4.4605184, 5.4605184],`
`        [4.820173 , 5.820173 , 6.820173 ]],`
`       [[6.179827 , 7.179827 , 8.179828 ],`
`        [7.5394816, 8.539482 , 9.539482 ]]], dtype=float32)>`
```

The contrast-adjusted image(s).

`ValueError` if `upper <= lower` or if `lower < 0`.
