Randomly changes jpeg encoding quality for inducing jpeg noise.
tf.image.random_jpeg_quality(
image, min_jpeg_quality, max_jpeg_quality, seed=None
)
min_jpeg_quality
must be in the interval [0, 100]
and less than
max_jpeg_quality
.
max_jpeg_quality
must be in the interval [0, 100]
.
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]]]
tf.image.random_jpeg_quality(x, 75, 95)
<tf.Tensor: shape=(2, 2, 3), dtype=float32, numpy=...>
For producing deterministic results given a seed
value, use
tf.image.stateless_random_jpeg_quality
. Unlike using the seed
param
with tf.image.random_*
ops, tf.image.stateless_random_*
ops guarantee 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).

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

if min_jpeg_quality or max_jpeg_quality is invalid.
