AutoContrast class
keras_cv.layers.AutoContrast(value_range, **kwargs)
Performs the AutoContrast operation on an image.
Auto contrast stretches the values of an image across the entire available
value_range. This makes differences between pixels more obvious. An
example of this is if an image only has values [0, 1] out of the range
[0, 255], auto contrast will change the 1 values to be 255.
Arguments
- 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.
