AutoContrast layer

[source]

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 setup.
