# Grayscale Augmentation

Probabilistically convert a percentage of your dataset's images to grayscale so your model relies less on color.

Probabilistically apply grayscale to a subset of your dataset.

* Percent: The percentage of images in your dataset that will be converted to grayscale. Higher values apply grayscale to more of your images.
