tf.keras.layers.RandomColorDegeneration

Randomly performs the color degeneration operation on given images.

Inherits From: Layer, Operation

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
)

input Retrieves the input tensor(s) of a symbolic operation.

Only returns the tensor(s) corresponding to the first time the operation was called.

output Retrieves the output tensor(s) of a layer.

Only returns the tensor(s) corresponding to the first time the operation was called.

Methods

convert_weight

View source

Convert the weight if it is from the a different backend.

from_config

View source

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.
