RandomSharpness class
keras_cv.layers.RandomSharpness(factor, value_range, seed=None, **kwargs)
Randomly performs the sharpness operation on given images.
The sharpness operation first performs a blur operation, then blends between the original image and the blurred image. This operation makes the edges of an image less sharp than they were in the original image.

Arguments
- factor: A tuple of two floats, a single float or
keras_cv.FactorSampler.factorcontrols the extent to which the image sharpness is impacted.factor=0.0makes this layer perform a no-op operation, while a value of 1.0 uses the sharpened result entirely. Values between 0 and 1 result in linear interpolation between the original image and the sharpened image. Values should be between0.0and1.0. If a tuple is used, afactoris sampled between the two values for every image augmented. If a single float is used, a value between0.0and 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). - value_range: the range of values the incoming images will have.
Represented as a two number tuple written [low, high].
This is typically either
[0, 1]or[0, 255]depending on how your preprocessing pipeline is set up.
