Randomly performs the color degeneration operation on given images.
Inherits From: Layer, Operation
tf.keras.layers.RandomColorDegeneration(
factor, value_range=(0, 255), data_format=None, seed=None, **kwargs
)
The sharpness operation first converts an image to gray scale, then back to
color. It then takes a weighted average between original image and the
degenerated image. This makes colors appear more dull.
Note: This layer is safe to use inside a <a href="../../../tf/data"><code>tf.data</code></a> or `grain` pipeline
(independently of which backend you're using).
Args:
factor: A tuple of two floats or a single float.
`factor` controls the extent to which the
image sharpness is impacted. `factor=0.0` makes this layer perform a
no-op operation, while a value of 1.0 uses the degenerated result
entirely. Values between 0 and 1 result in linear interpolation
between the original image and the sharpened image.
Values should be between `0.0` and `1.0`. If a tuple is used, a
`factor` is sampled between the two values for every image
augmented. If a single float is used, a value between `0.0` and the
passed float is sampled. In order to ensure the value is always the
same, please pass a tuple with two identical floats: `(0.5, 0.5)`.
seed: Integer. Used to create a random seed.
Example:
layer = keras.layers.RandomColorDegeneration(value_range=(0, 255))
images = np.random.randint(0, 255, (8, 224, 224, 3), dtype="uint8")
labels = keras.ops.one_hot(
np.array([0, 1, 2, 0, 1, 2, 0, 1]),
num_classes=3
)
segmentation_masks = np.random.randint(0, 3, (8, 224, 224, 1), dtype="uint8")
output = layer(
{
"images": images,
"labels": labels,
"segmentation_masks": segmentation_masks
},
training=True
)
Methods
convert_weight
convert_weight(
weight
)
Convert the weight if it is from the a different backend.
from_config
@classmethodfrom_config( config )
Creates an operation from its config.
This method is the reverse of get_config, capable of instantiating the
same operation from the config dictionary.
if "dtype" in config and isinstance(config["dtype"], dict):
policy = dtype_policies.deserialize(config["dtype"])
| Args | |
|---|---|
config
|
A Python dictionary, typically the output of get_config.

| Returns | |
|---|---|
| An operation instance. |
